@13wavell Yeah...I don't "Get" track bikes. Do they not use derailleurs because of weight and "aero" reasons? I know track bikes don't have brakes for those reasons.
@marcoss92 This is not a top speed comparison for road but a measure of how well you can spin in circles because in track racing you need to be able to get your legs to at least 170 if you want to survive any sort of point score. because you only have one gear and if you go much bigger the a 48X14 you will pay for it with all the surges. some races have you pushing close to the 200 rpm mark. you will do more damage riding at 60 rpm then at 180 if you have good technique.
@pcfxer yeah coz you have only 1 gear and it is a fixed gear then there is no need for a rear derailluer. its not because its more aero. the only reason you have a rear derailluer is so that you can change gears. plus a derailluer does not work on a fixed gear. any way. im not going to try and explain it any more google it if you are so lost!
You would go faster on a larger rollers because the larger roller has lower friction in its bearings than the smaller one in the same speed. Because the difference in the radius...
If your RPM is 188, you must use 48T front and 15T back.. On a compact crank with 50/34 and 12-27 casette with 188 RPM the top speed is 101.6km/h.. I doubt your RPM cannot be 188... breaking 80km/h with the same gears require 148RPM.. (80.4km/h using 50/12) with 172.5mm CrankArm
@13wavell I know what a SS is. Why would you NOT want to change gears on a track bike? I've never track raced...I'm just a curious roadie. You can be single speed with a freewheel too...not nearly as manly as a SS with breaking by your feet.

@pcfxer its a track bike. (fixed gear) so you dont run a derailuer etc... only 1 gear

the crank is spinning like a wheel of cae
@annonumousviewer THANK YOU! I never thought about rules; thank you for clarifying.
PS, cool triple post ;P

not sure. i dont think so. you can get larger ones but i am not sure if it would make you go faster.

@marcoss92 oh yeah coz i hell do this training every day!!!!!
plenty of times spent on the rollers? you're pretty stable while "sprinting"; just got a kreitler, still trying to perfect my balance :/

@13wavell
haha you shut him down good
Big question here? Is that an internal gear hub if it isn't why did you remove your cassette and derailleur?
Would you be able to go faster on bigger rollers?

are the rollers fixed (another stupid question to ponder)
What ratio are you using? i use i 48/14 and just hit 78
@marcoss92 You are more likely to injure your knees sitting down wrong than you are doing short sprints on rollers. Don't be stupid.
I do 93 km/h with 52/14
Loooooserrrr ! haha
