I street race my Bmx Bike against road bikers and other bmx bikers and mountain bikers but I have a 30t sprocket in the front and 9t cassette in the back with odyssey Tom Dugan 100 psi max tires and I run 175mm cranks to and I've reached 31.9 mph on flat Road in a short distance sprint and I've smoked so many road bikers it's crazy and funny too because I'm 6 ft 1 and 187lbs and riding a Bmx beating road bikers on flat Roads and downhills lol it's so much Fun
In the 80s and 90s, 20" bike gears were something like 45 - 16. 170 -175 crank arms off the shelf. My indoor gear was 44 - 16. Crank arm 180. My out door big track was 46 - 16. 180 crank arm. My cruiser gear ( if I can remember was 42 -18. I was tall. 6ft 3. 190 lbs. Big guys couldn't spin like little guys. So we ran bigger gears. Have you ever seen a giraffe spin? Very awkward lol. I miss racing. I don't understand these tiny gears you guys run today.
May I know what is the different between big chainring with big cog vs small chainring with small cog. Example: 44t:16= 2.75 & 25t : 9= 2.77 . Is it big chainring/cog can last longer and small chainring/cog give more space to perform stunt?
I'm torn. I LOVE 28 in the bowls. It gives you that one useful crank when you need it. But riding small obstacles and using pedal pressure, 25 gives you so much more control. I need two bikes is the answer, lol.
My friend had a 28t sprocket in the front and 9t cassette in the back with odyssey psi max tires and he accelerated very quickly and his top speed was around 28 mph to 30 mph in a short distance sprint he beat many Road bikers and also beat my road bike too
@@johnduke4120 and my friend has great endurance he did bmx racing for years growing up so he built up that endurance and hes just crazy fast and super light like only 140 to 150 lbs that's it and he doesn't smoke either and never did just like me! We both have very strong legs and strong core and excellent Endurance
I did 34 mph on a flat road recently on my road race bike and it felt amazing and that's because I train almost every day and go fast all the time and on my bmx I went 31.9 mph on a flat Road a few months back and that's very fast for a bmx Freestyle bike to go you know but that's because my legs put out over 1,880 watts of power when sprinting because I street race all the time and no one where I live wants to race me because I'm that fast and I've done 40 to 41 mph on the bmx freestyle bike before down hill thats probably the max it will go too and the road bike has gone over 42 mph downhill before but that road isn't close to being maxed out Because it's got a 58t chainring and 11t cassette so it's big gearing!
I don’t know much about bikes but my son wants his 20 inch mongoose to roll faster because he rides his bike to school. He want less pedaling and more speed. What sprocket and chain set is best for his application?
Depends on the rear sprocket but yeah a 28 is good maybe a 30 biggest I would go is 32 see what’s on the bike and the go from there normally the bigger the front sprocket I’ll be harder to pedal, but you’ll get up to speed quicker the smaller the sprocket it’ll make it feel like you’re not peddling at all and barely going anywhere🎉
A little bit of course question, are the free coasters much louder over a freewheel hub, when coasting? And when faking on a free coaster, when you do pedal is it a fluid motion forward or a second pause? Thanks
Hi I have a question and I hope you could help me with it, I would like to know what size sprocket should I use for just bike riding long distances for example 3 miles one way but I don't want to get my legs tired out, I have a (Nice) Schwinn BMX but it's hard at first to pedal because it has a 44 teeth sprocket with a 18 teeth back tire, I just want a well balanced gear ratios for bike riding short trips or even 5 mile trips.
Good lord… finally! Thank you for explaining in real life terms and not in chain inches and ratios and just explaining what does what and what to expect.
Marketing technique IMHO. Your sprocket still flexes when you pedal hard from the start, meaning wear and tear sets in more if you ride hardcore daily. Smaller sizes really dosen't matter, but with ample amount of pressure each day gives it more probability of cracking or chipping on the metal. I always run 39 or 40T to 16 FC, so if I torque for speed it'll be a speed I can handle, or at least something enough to clear a jump at full adrenaline to make me cautious and think WTF am I doing.
I had a question I have and SE big quadrangle I only use it on bike path on the beach but I want it to go faster without peddling as much what should I do to make it faster ?
29in takes more effort to get rolling. I’d say 25t and you should add more teeth in the back (like 10 or 11t). Otherwise you would have to go smaller on the front sprocket like 23t. My 24in at 25x10 feels the same as my 20in with 25x9.
You'd need legs like Roberto Carlos to accelerate with gearing that high😅the top speed would be insane but starting on a hill would likely be impossible. 30/9 will give you 30+mph when you max out. Anything higher is going into overkill territory imo
5'11" long torso. Haha I'm running 28/9 on my 20" with 165 cranks. Was fine until I built a 22" bike with 23/9 with 170 cranks. I wonder if 170's would make the 28/9 20" bike feel better than the 165's. Thanks!
I got an old mongoose layin around with 40 on it. I think im gonna put 9 in the rear for ridin around the neighborhood and see what happens . Worst case i just swat it back.
you didnt say how many teeth in the back. is it 9t? what are the effects of a 9t in the back vs a 16t in the back. What is a good ratio if i want to become the wheelie master?
@@officialtdogg 25/16 I'm imagining a hamster on a wheel lol. You'd probably be faster jogging😂 Ive got a bunch of sprockets. Running 30/9 currently. My daughters bike came with 32/16 and she isn't very strong yet but still maxed out way too easy and couldn't keep up. I changed hers to a 36t sprocket and now it's more like my original 25/9 gearing and she's much happier being able to go faster.
