First of all I need to give credit to my friend Danny his Instagram is instagram.com/dannyswellchasers/ I would not be able to product this kind of product without him, if you are looking for any kind of professional production. dm him, his video skills and editing skills are top notch!!! Now for this video, This video I had so much fun filming and mainly I filmed this just because the stars lined up and had 2 top tier demo bikes in my store at the same time and was able to have some fun on top tier bikes. I wanted to make a visually cool video that was enjoyable content, the results at the end I would love to know your feedback on the case because there was a clear winner on paper, but is that really the truth. Please let me know if you want me to continue doing more videos like this in the future :). Thank you to everyone who is always around always messaging me and emailing me. I just like to have fun on bikes and ride in some beautiful weather
bruh, I was just about to say wind could have been a factor. Sometimes winds may me moving in the same direction but there are times when the wind dies down a little or you might get a few small gusts here and there. If you had all the time in the world it would be nice to test each bike 3x each and take the average of both to compare. Great video regardless~ I'd still take the BMC over the SL8 tho haha
first video from a long timre with hdr turned off so I can easily watch without switching a display profile! So from my perspective huge upgrade! 😀 and ofc very nice video, at the end we most of the time buy just a nicer color anyways ;)
From living in a windy area I know it doesn’t take much of a difference in wind speed/direction to have a massive difference in bike speed.. you need to do the test again and: Pick a non-windy day Do a circuit (not a straight road) Do two rides on each bike and take the average
You have to repeat the test many times and average it out to come to an accurate conclusion. You would also have to alternate the order as winds pick up from morning to late afternoon more times than not (especially around the east coast). As little as 1 mph of tailwind/headwind can explain the difference.
I don't think you need apologise for any deficiencies in the test, it's pretty good, and if you want to do more of them this is a learning experience. 1W difference between runs is on par or better than some of the GCN efforts, and they're ex pros! You can't do anything about the wind, but maybe you can use a gadget to log the wind changes between runs and estimate the effect? Does Peak Torque so something like that? Traffic is a PITA and those vehicle blocking the lane could easily account for unexpected time differences. All I can suggest there is go out at 4:30am - 5:00am before the traffic builds up, but I think everyone understands that's not necessarily possible with family and job commitments. Power meter pedals swapped between bikes would be useful, run them in parallel with the Quarq meters you would see the difference, it probably won't be much though. Probably the toughest challenge is getting the bike setups identical, and holding an identical body position for the duration of the run. Slight changes in you body will affect the result quite a bit, but you're not Dan Bigham and you don't have access to a wind tunnel, so I wouldn't worry about being perfectly optimised. Maybe one of those phone apps could help? What matters is being consistent, but if that sucks the fun out of it then just don't worry about it. Most important thing is just to enjoy it, and just share your thoughts on the experience of each bike. Anyone complaining the test isn't perfect is in the wrong place.
The video is great content, very nice to see your opinions and facts about the bikes. As far as the science it’s not accurate, not because the power meter, but because in south Florida the wind is never flat or perfectly from the side; perhaps if you did 2.5 miles each way it would be closer. But again, your opinion and description of the bikes is very good content.
BTW, I used to live there, and rode A1A all the time. The wind.. if you know, you know. The difference in the result could simply be because the wind, as you know, is stronger later in the afternoon.
Cool foortage! Is this recorded from a drone or someone with a motor bike? In terms of the test, yes it's uncontrolled environment + diff pwr meter. I think it would have been better if you do a back and forth route. I am not surprised SL8 is gonna be faster than that BMC, but the 1mph avg speed is quite massive. In a race, that's almost like between 1st and last place
it was filmed from a guy on a super 73 and a nice camera, it was awesome, and yes I tried my best and I was happpy with the results of staying within 1 watt on my computer and doing what I was suppose to do
I suspect the gearing being different on each bike may have created a difference too. I agree narrower handlebars are way more comfortable. I am bias to the SL8 myself. Great Vid
Gearing shouldn’t change anything when power is controlled. Power (Watts) = Torque (Pedal Force) x RPM (Cadence)/9.55 You can put out 220 watts with higher torque, and lower cadence, but also with higher cadence, and lower torque. Given the drivetrain losses should be identical, 220w should be good for x speed provided all other conditions are the same.
This is good.. However you should run that test with the same exact tyre/width. And maybe run 2 or 3 times for avg time and then up the wattage and do it again and get an avg. Weight does not matter much on flats. You couldve encountered some more winds and that's the only reason sl8 could be faster.
they killed the design and riide fel of the new sl8 just it got the bad rap for the speed sniffer but it is 100 percent such an amazing ride quality for comfort but stil has that snapy feel
Forget the bikes....what color were those socks GC? If Chris from the Nero show (the resident cycling fashionista) does not roast you for these you will have gotten off too easy!
I would (maybe will) definitely go for the BMC, but one honest comment that I already hate: Testing aero bikes with overweight and sitting straight and only pusing slightly over 200 watts? Sorry, but this is far from a serious test. Bikes like this, you test fully trained, in aero position and at 45 kmh at least.
He's testing it off the shelf like most consumers would do when they buy it. Let's be honest the average consumer is not going to be pushing 45kmh... They just want to turn up to group ride looking the part.
@@ZwiftDude if you test it like this, I honestly think you do not understand a think about aerodynamics, nor the forces that apply when riding a bike.... A test like this is worth... nothing. Test it 10 times like this and you will find 10 different results.
Sure you might. But that's being Scientific. Only a small fraction of people think like that or the science behind aerodynamics. If they want an S Works off the shelf, they'll buy it. @@max551982
This video had so much potential but it all went down the drain when you had a 42 vs 36 cm bars and complimentary different wheels tires. You could have least used the rival wheels for both. This test is pretty useless this way.
If you do another test, you should ride both directions so it sort of cancels out the wind. And yes, use the same power meter. Look forward to the next video.
it is what it is, Im one guy trying to control the elements, the winds were a tailwind and guests were up to 16mph that day, people perform speed tests in wind tunnels and say that data is not real because of cross winds and other elements and then when people are on the bike in the real world people ocmplain they need more control, I controlled everything I possibly could and stayed within 1 watt on my computer with the equipment I had to deal with
@@GCPerformance18 not a critic of your test at all, for me it was great entertainment. But I find it funny to imagine that Jesse is probably fuming that the SL8 won again 🤣
yea of course, but honestly to swap out an integrated bar is costly for a dealer, to eat a 600 dolar bar and swap out seats the margins go down real quick on top of a 300 fit
If you’re a recreational cyclist who can afford a $15,000 luxury bike, you can afford a bike fit. If you can afford a $15,000 bike fit, and ask for a free bike fit, you’re an a**hole. Pay people for their labor. You can clearly afford to.
@@NoahStephens it's not about the Bike fit, lul. It's about swapping out parts Like stem/bar, cranks etc they aint cheap. Not to mention the labor. Which I dont need, cause I do everything on my own.
Good to know but performance is a general term. I m interested to know in which aspect SLR performed better? Aero speed, climbing speed, handling, comfort…
@brunomiguelgomes700 lol..knock it off..they're just bikes at the end of the day..I have no loyalty to brand..just quality..I own several bikes from trek , cervelo, specialized..they're basically all the same w a little tweak to each one..
@Questioneverything72 the SL7 sworks is quicker but the SLR madone is faster..the madone holds speeds better at 25mph..even though the madone weighs 16.6lbs with tpu inner tubes and a pair of roval CLX2 wheels(I don't like bontrager) i find myself slightly faster going up hills..maybe because of the aero properties??? Who knows..lol
Very cool comparison. You are in the envious position of being able to ride amazing bikes. The weather is wonderful, though I would find the flat terrain and constant traffic to be tiresome. Keep up the great work. Bikes are cool.
@charlesmansplaining lol..believe it or not it's cheaper to buy the frames and build them..I guess they look at me as being rich too...most folks don't know I cut corners..I always buy brand new frames a year later(cheaper) and then add sram red or shimano di2 ultegra with my wheels(roval rapide CLX2)..lol
it comes stock like that and literally 5 years ago this use to be the norm, the whole industry back in 5 years were winning the tour de france with 42 bars
It’s a great point. Just bought an SL8 and was shocked the Rival bar didn’t come in a 130/38 never mind 36. It’s 2024. WT guys have been turning in the hoods for 3 years now. BMC can do it, so can Specialized.
1w is not even .5 mph You in in the slop of the measurement .. the bikes are very even . The differences likely due to wind and traffic 1 mph with all thing equal is gonna require ~20w … so data is fishy but thanks for trying 😮 and no way SL8 is 20w faster then BMC
By the way, the weight of sl8 is 7,28. How come this weight? I have got a Scott addict rc pro 2020 with dt swiss arc 1400 with a weight of 7,1 for less than half the price... (also with pedels)
I really like the comparison of how it rides. I would love more comparisons, on you riding different bikes. you can find specs on any of these bikes, but how it rides/feels that’s what riders wanna know. Madone next?
Love the side by side this is awesome content. Please do more side by side contents of these super bikes. I guess the time and speeds would be better to have a few more runs to be averaged but i love how you go after those points at the end. Still just being able to experience what you are feeling on those bikes is awesome and something that no other youtuber is doing. Ty so much!!!
To have any meaningful data you would have needed to do runs in BOTH directions, at least 3 times each. i.e. 30km on each bike, with 6 x 5k results for each bike. Out and back with BMC, out and back with SL8, out and back with BMC, out and back with SL8, etc...
An exaggerated performance difference in this "TT-test", although the 2 different power meters reported only 1 watt, a negligible value even over such a short distance. Yes, the wind could be an acceptable reason of this massive difference, as well the smoothness of the roadway surface. Btw, I totally agree about the quality of these 2 bike: the best bike out there. As well the 🇮🇹 Colnago 🇮🇹 (C68 o V4Rs).
I respect but you don't need a video for that because the conclusion is: both are awesome!!!! pick the best for you and ship the other one for me. #noregret
2yea I do not know why the elevation was like that, doesnt make any sense, but also this happens on my 30 mile rides and 60 miles rides I run the exact same routes all the time, and the elevation always comes back different I do not know why unless hammerhead is just reading it not consistent
The BMC looks better for sure :) But MVDP results proves that Canyon makes the best bikes ahah :) Oh no sorry Colnago bikes with Pogacar ! Or Cervelo maybe with Vingegaard... ? Hmm Remco is on a Tarmac right ? Sorry I'm lost now, lol :)
Your position is one of the biggest factors in this test. There could be a significant difference if your stack and reach values vary. I’d say the variance in these result has more to do with your position and wind changes rather than the bikes.
Yea I tried to stay in the hoods the whole time and both bikes had same stem length and also lowered the exact same. The only thing was bmc had the 36 bars. But that’s there own winning formula. I tried my best to stay true to
It's sad to see a video like this. I am pretty sure that you could make a low budget bike go faster than the SL8 in the same comparison test. What is the point of this, if not marketing of specialized bikes hidden as real world test.
I live on the coast, Huntington Beach Ca. where there is onshore wind mostly all the time, the wind is low in the morning and builds during the the day. Chances are the wind velocity is more of a factor than it is likely the specialized is 29 watts more slippery. Just saying. BTW fan of your channel, keep up the good work AND I am a few days away from getting my own BMC Teammachine R 01 Mod. :) @@GCPerformance18
Thorough testing takes bloody ages. You'd have needed to do 4-5 runs in both directions on both bikes to get a representative result. For the sake of a RU-vid video, this was interesting enough from an experience POV. You can't say there's a difference between the two though; the standard deviations would most likely overlap over several runs. It's scary how many 'testing' videos (not just in cycling, golf is one of the worst for it) completely ignore standard deviation. It's one of the most vital bits of context when comparing anything.
Enjoyed your comparison. How tall are you? Approximately how much do you weigh? Do you get concerned about the seat stays getting damaged? I am sure at that price, you would recommend getting bike insurance? Would like to see a comparison of bike insurance. Would also like to see a review on the new Factor Ostro VAM. Thanks.
Great tests. And this shows how hard and time consuming it is to do comparison tests. I guess a way to make the test more comparable is to do it with a buddy and pedal powermeters. Then both ride the same distance (as much straight line as possible like you did) about 100m behind each other with same wattage. Then switch powermeters and ride again for the same distance (in the same direction - not back - so any differences cancel out). And I also think that using the same tires would make it more comparable. They are really responsible for a measurable part of friction and can actually vary a lot. (Switching tires is not comparable to switching wheels or steering bar as those changes would be way more costly.)
Your kit is 🔥🔥🔥. My team is currently looking for a company to do our jersey. May I ask which company you used… right now we’re using Jackaroo but the guys are complaining they need a better looking kit.
Tough to do these comparisons given the variables it needs more runs to try to average them out. Obviously the wind, but also how you sit on the bike, slight fit changes - saddle height etc, being warmed up & a bit looser vs earlier on in a ride, riding over slightly different parts of the road, tyre differences if tge wheels aren't swapped, any change from vehicles or parked cars you pass etc etc. The powermeter differences can be reasonably large all mine measure differently. Even using an aerosensor to help you need to be strict on your testing protocol.
yea I know I was trying to get a test data for real world use, those roads I ride everyday up and down so I want to see how the numbers perform on that road
Are the bikes geometries different ...so if I ride a 56 Tarmac, and just make the 56 clip level, would I buy a 54 or 56 BMC as their configurator keeps giving me a size 54 ...getting the smaller size makes me nervous. The actual measurements look fine (comparing websites), was just wondering what your opinion is on this matter ?
“Is it 1mph faster?” How is that even a question? You pointed most of it out yourself; 1. No control of the environment, wind speed, wind direction, traffic conditions. 2. Different power meters on different bikes. (Did you even bother with a zero offset?) 3. How well controlled was the starting and stopping of the segment? was it GPS controlled? or simple lap function? 4. 5 mile pan flat ride? This is barely a step above a parking lot test ride. If you want to “get to know” what each of these bikes likes/dislikes, you’ll probably want to do some climbing and descending as well. If I’m the BMC rep watching this I’d be pretty pissed, watching someone’s completely unscientific test throw shade at their latest release. Now, all that said, had the results been the other way around, I’d probably want to point out the specialized is at a disadvantage with a shallower wheel, and wider bars. Anyhow, cool to see some different types of content, but this type of content may be better left to the more techy channels if you want to make a prescriptive statement of performance. (Peak Torque, etc) What I would be interested in, is more about how they feel to ride in different conditions. (Apologies if this came across harsh, I don’t mean it that way.)
Yea I mentioned in this video that it wasn’t dead on data, I did everything. I could to control the variables I could. And put these bikes to real world tests. If you watched the video. I tried running this test where everyone would be riding bikes. I ride that route everyday so I would like data on where I ride at. 2, yes literally at the end of the video I told everyone I zero offset both cranks. 3, I mentioned in video I started both rides at the same spot and ended the ride both times myself on the hammerhead. No lap function, just start stop and recorded the ride. 5 mile is a great test subject. But also if you heard me I had the bmc for a week and recorded a 60 mile ride on the Saturday, and a 30 mile ride on Thursday which is on my Strava, that you can see. Which the bmc bike is one of the fastest bikes I ever road. This is not hard data that everyone has to follow. I made this video for fun. Next time I will use pedals to control it even more
Not just the wind would have had a huge impact, also the different tyres/tubes and therefore the rolling resistance. Put the same wheels on both bikes and the assioma pedals, try hitting a day with no wind, and repeat if you have the time.
Lost my only client today. Glad i didn't make that bike purchase yet. I think I've been chasing cycling marginal gains too much be ause they couldn't pay me enough
