You would assume a hardtail MTB would be more efficient compared to a big enduro beast right? Surely the rear suspension of a big travel bike would soak up some of your hill-climbing efforts? Join Neil Donoghue as he runs a series of MTB tests to see whether or not this is true, and if so, just how much of a difference it makes to you when out riding!

Now do the same test in reverse order and present the averages of both days...so you're not comparing your tired run on a slower climber to a fresh run on the fast climber....otherwise the data mainly shows fatigue in time.

Why should he? If you understand the data and what he said, in terms of efficiency the full sus was nearly exactly the same as the ht. Its just a bit more heavy. What do you expect in your test? The full sus magically get lighter?

I would agree more if the difference between the bikes was bigger and the videos conclusion was that enduro bikes still suck for climbs. If he did the video with a propper rest and control tyres, it would likely only prove the same point but with two or three seconds taken off, which is not worth it for an overly commercialised channel like GMBN where this video was likely just subliminal marketing for a sponsor anyway.

@markyp1965 Год назад

I ride a carbon Transition Patrol, 170mm up front, 160mm rear with a coil shock. I never bother using the lock out and I don’t worry too much about how quickly I can climb. The Patrol pedals well, and as a steady climber, I’m happy to stick it in a comfortable gear and just spin my way up the hill. All about the fun of descents for me, with some chilled pedalling in between.

@dinunclv Год назад

I like how my Slash climbes too, but the idea is that you will not win an xc race with it.

@JAvellino669 5 месяцев назад

Fantastic video! Honestly wish I saw this before getting my second hardtail. I do some road to get to the trails, so I went hardtail for the efficiency. Turns out I'm not gaining much of that, while also losing the comfort and traction that comes with full sus. Lesson learned!

@glennward2436 Год назад

Interesting stuff. Lately the difference in climb times between bikes seems to come down to the tires. Love to see the 170mm Canyon in control test with different tires.

@gmbn Год назад

Thanks, Glenn! It was so interesting to see how the stats compared between the bikes! 👍

@PiloMegaTron Год назад

Nice work! But more of a casual comparison with some stats involved, then real science ;) Interesting though. Thanks for the upload! :) I run my BMC TE01 (hardtail) for max efficiency on xc type surface/distance, and my Santacruz 5010 for technical stuff (up AND down). Used to do it all on the BMC before i had the SC though; also crazy fun, maybe even a bit more adrenalin (= less confidence/comfort?) on the same 'downhills'! :D

@blindspotclinic Год назад

You should do this again, using the same wheel/tire combo. Just for science sake.

@jeskli11 Год назад

If he were on the same tires, the bikes were the same weight, had the same drivetrains, same CdA etc., he would get absolutely same times regardless of what bike he's riding or what suspension mode he's on had he ridden at the same power. If the lockout totally stiffens the suspension and his riding position was set exactly the same on both bikes, there would be no difference between a hardtail and any full sus. The efficiency difference would first be seen with the suspension open (the run he threw away) - then the precieved exertion (and with that also heart rate) would be higher depending on how effective is the power transfer of that particular bike as part of your effort is put towards compressing the shock, therefore he would either not be able to put down the same power or hold it for the same time. There have been already some experiments done on this topic, if you're interested check out for example Dylan Jawnson here on RU-vid.

@pikymalvo Год назад

Very interesting topic! It would have been more comparable with both 29er and air shock. I hope that you will do it in the future

@jeskli11 Год назад

If the bikes weighed the same, had the same tires and drivetrains, the position was set the same, he would achieve exactly same times regardless of suspension settings as long as he kept the same power output. The difference comes with the suspension open (suspecting the lockout stiffens in totally), as that in that moment you are putting your energy not only to the pedals, but also to the compression of the suspension. That results in higher precieved exertion (and with that usually higher heart rate) and therefore you are either not able to hold the same power or you can't hold it for the same time. But even with the suspension open, at the same power output he would get the same time.

@blurglide Год назад

It'd be interesting to see how much is suspension and how much is weight by weighting down the hardtail. I'd also like to see a technical climb. On a lot of tech climbs I'll actually open up my shock. Letting the bike absorb the bumps is less work than doing it with my body

@gmbn Год назад

@condek92 Год назад

@thebikehub7421 Год назад

I have to say long travel bikes plus how long they sit at a slack point really makes them harder to point around flat corners - I’ve found I can go fast on my short travel bikes in certain spots cause of how much energy it takes to get around obstacles on the extra long bikes / the shorter travel just snaps through corners like a champ - yes they’re efficient but I think the sweet spot is 140-150 to keep that snappy feel if you go any higher you better hit the big stuff!

@mlee6050 7 месяцев назад

I guess be fun, advised 150 or 160 rear travel and 150 to 170 front forks but wanted to get 180 so unsure if drop to just 170 instead, but in future was planning to take on london to brighton

@madched Год назад

The GCN team did a similar experiment where they matched the same power range across different bikes to show the difference in weight /performance has on output speed. This would be interestring to see against hardtail, short travel bikes and longer travel bikes.

@shrinkingshrimp Год назад

I tought I will keep my upgraded budget hardtail for more climbing intense sessions, then when I recently invested in a full sus, I was amazed how much better I can climb with the new bike, so long story short: waiting for the season to kick in to sell my HT for a better price. My theory is a HT is only measurably efficient when sprinting or when standing up, thats when the shock absorbs your effort the most. But I'm not a pro racer (yet), I do not sprint to the finish line, I usually do my climbing seated. Even then a remote lock/climb mode for the shock would be my choice. And when some rocks are introduced to the wheels the more traction of the full sus is usually more efficient.

@leftaroundabout Год назад

Agree: as long as you're seated, modern rear suspension only makes a marginal efficiency difference. However, one thing I like about a hardtail is that it actually encourages making an effort, putting in sprints and trials-ing up technical hurdles. A full-sus encourages staying in the saddle, the climbs are slow and _feel_ even slower, and when you do get out of the saddle then it really does seep power.

@theprofitmohamhead1268 Год назад

The full suspension bike is a mullet. Was the hardball as well? If not he travel rotation circumference difference might explain the quicker time, etc. What say you?

@PeakTorque Год назад

Not sure what youre trying to prove if you dont keep the power consistent? The thing you really need for this test is gas analysis, because output power on the bike doesn't measure the input cost on your body.

@endianAphones Год назад

Thinking about getting a new bike. I'm a bit undecided between something like the Spectral (Trail/All Mountain'ish) vs the Torque (enduro'ish). I want it just for having fun, which is a bit relative, so I don't really care about pedaling efficient, but I also suck and I'm not getting any younger, and getting the Torque is defenitely overbiking a bit... Not sure if I still should go for it just because, or if it will be too bad at more mellow stuff... Any thoughts on this would be appreciated.

I've been hoping we'd see Fox Live Valve on the 38 this year. I think that tech is the possible future with the geo changes and technology I bet in a few years its going to get harder and harder to pick a modern geo trail bike over an enduro trail bike.

I did a 40 miler last summer on my 180/170mm Evil Insurgent with coil. On a long ride like that the weight does catch up with you, the XC bikes and even lighter enduro bikes pulled way ahead with similarly fit riders. There is a reason XC racers aren't all on big enduro/freeride bikes. ;)

Does the nukeproof have 140mm of travel? Plus has a fairly slack headtube angle.

It is interesting. My 2019 capra has 180mm travel and it climbs ok seated but the front end wanders and you certainly lose more effort when standing. Compared to a nukeproof scout it felt way less efficient but i dont know if it was wheel size, 5mm shorter cranks or the fact that it was hardtail. I think the big travel bikes are phasing out the middle ground 150mm travel bikes leave lower travel xc and 150 to 180 "all mountain"

What tires are on the bikes. I’ve learnt that the carcasses on enduro tires really are slowing you down. I’m not sure how strong that effect is on the way up since you’re quiet slow, but I’m sure there is an influence.

@no1cr500racer Год назад

I would like to see the same test done, but! To be fair, add weight to the hardtail so it weighs the same as the full suspension bike, that would eliminate the advantage of a lighter bike, and then focus in on evenly matched weight bikes, one full suspension, one hardtail, which one climbs better.

@elirocha8548 11 месяцев назад

Is the suspension adjustable?

@DjDolHaus86 Год назад

It can't really be argued that compressing the shocks with every pedal stroke isn't losing efficiency but this could be balanced out by improved traction on rough surfaces in certain situations. Ultimately, like most things, it's a compromise

Last time I started building a bike with "less travel for more XC" I ended up with a 180/178mm Nomad :O The shortest travel bike I own is a 160/140 Shuttle ... and a 150/150 Bronson... Well, the shuttle is an e-bike ... but the Bronson doesn't climb any worse or better than the 170-180mm travel bikes. That said, I climb sitting down and barely stand up.

climbing with a set power that could have been repeatable (around 150W) would have provided some clarity. using your perceived effort as the common denominator just created a lot of gray areas. noteworthy that the KJ totals were opposite from what you might expect. total work on the hardtail was 20KJ more than the last run with damper wide open?

what does the travel on the suspension to do with how good it is at climbing? it is just suspension, if you have done the sag then it should climb as good as a mtb with less suspension travel, it is the geo and design of the frame/chassis that decides how well a bike climbs and the suspension is there to swallow the terrain.

@HavokTheorem Год назад

You are ignoring the meaning of the words you are using. Acceleration is change in velocity, or in this case, a change in rotational velocity. A smaller wheel with a lower moment of inertia does indeed accelerate faster when spun. However, it also deccelerates faster. When you hit an obstacle, your wheel will slow down more easily. There is no free energy to be had here. On the other hand, a smaller wheel loses energy through rolling resistance over chunky terrain. Imagine riding a bike over a curb with a wheel that has a radius of double the curb's height. The curb will strike the tyre at 1/4 of its full height, which corresponds to about a 45 degree angle of contact. This means that half the force of the impact will work to slow the bike down, while the other half will work to raise the tyre above the curb. Now imagine you halve the size of the wheel so that the curb reaches halfway up the tyre. Now, it's a head-on collision between two faces. 100% of the force goes into resisting the forward motion of the bike. This is based on trigonometry and vectors, but it's pretty simple to intuitively see and test, and it corresponds strongly with the efficiency of rolling. So no, you're not right. Acceleration has nothing to do with efficiency over an extended period of climbing. It is surely beneficial to have light wheels for their benefits: lower unsprung mass gives improved handling and suspension behavior, and being able to quickly accelerate is useful on technical climbs.

What 180mm travel,i have a 80mm travel

@TheButlerNZ Год назад

#AskGMBN So now go and try pushing the bike up the steepest track to the top vs riding the rideable way up and give us the result. I am extremely Mediocre (hence mediocre videos) and on my local track it takes just over an hour to ride my 18kg bike, 3kg pack and 80 kg bod to the top. The other day I was so exhausted I rode 1/2 the way then pushed up the barely rideable firebreak to the top... stopping a couple of times to overcome the odd stroke... I made it to the top in 50 minutes... better than even when I was (lets not say fit, lets say... less unfit).

Its like comparing apples and oranges, would have been better comparing a long travel fs vs 120/130 travel fs

@dit4963 Год назад

And your comparison is like comparing oranges with mandarins :) The point of this comparison was to see how big the difference is, not to see if there is a difference. D'oh...

Big travel, bad climber? Nah not for me, if you don't make excuses and get on with it. It gets done. 😅

True they are awesome for commuting then hitting the trails on the way home.

@@HavokTheorem have you tried a modern hardtail, before making this comment?

@rickywoods3101 Год назад

@@jeffreydzialo I have both and still like full suspension by far for what I usually do.. I only use hard tail for really light trail and riding on the road or in town .

@markdance574 Год назад

As much as I love the channel I do feel you guys are rather brand loyal and also brand disrespect- Scott make fantastic bikes with systems that allow the suspension to be modified on the fly which greatly improves both efficiency and the riding experience yet these bikes are almost never reviewed. I have a Scott strike eride 930 and it’s a great all round bike for my riding needs

@colincoulthard3021 Год назад

GMBN isn’t really a bike review channel? Bike Radar, Guy Kesteven are more about reviews.

@Pienimusta Год назад

You must have zero idea how business works. They are not doing this for charity.

@edgarm2036 Год назад

What are you talking about? They are not reviewing bikes. They have sponsors and they are proving a point, it shows you have no idea what GMBN is all about 🤦🏽‍♂️

@MrSupermugen Год назад

The funny thing about scott bikes, they are not very efficient even with the lock outs. Scott bikes generally ride like rubbish and the new "genius" is better but still lacks alot of things and they keep ruining their bikes with integration. Scott is not a brand you consider when you want a "proper mtb"

@markdance574 Год назад

@@MrSupermugen that’s odd as when you look at rider and bikes who have been winning championships Scott bikes are topping lists

@jasonrodwell5316 Год назад

Am I the only one who sees the flaw in the logic here? How does pitting a full sus with 170mm travel against a hardtail tell you anything other than the difference between a full sus with 170mm travel.. And a hardtail! Those apples look nothing like those oranges.

@jasonrodwell5316 Год назад

Its interesting in it's self especially that they were so close given the difference but not very scientific at all.

@RCKING1 Год назад

This is a terribly done test tbh. You should ideally use the same tires and pedal at the exact same watts. Even better would be to add be to also add weight to the hardtail to make it comparable

@High_Octane Год назад

for crying out loud you guys.... PUT THE DATA BESIDE SO WE CAN COMPARE! do you want me to take a freaking picture so i can compare numbers, neil dose not even go into enough detail to get a proper comparison, just lists a bunch off. you always do this and makes these comparisons frustrating to watch.
