Chain stay

[just.trials]

what does a chain stay do?


Thx

It's the part of the frame that the red thing is covering.

keeps the rear wheel connected to the rest of hte bike.

Ifyour talking about what it actually is the guys above have got it right.
But im pretty sure hes asking what likw a 380 or 400 'stay length means.
Essentially the longer the chain stay the farther the rear wheel is from the bottom bracket.
Shorter chain stays make the bike more responsive so you can gap farther and stuff. But they also make it more twitchy and therefor less stable on the rearwheel.
Hope this helps,
Ian

im about 99% sure youve got that backwards.

Longer better? longer worse?:wtf:

[Elan]

longer= less stable on rear wheel
shorter=more stable


from my experience, having a longer cs meant that i could gap further, im guessing due to leverage. but it wasnt as easy to land gaps, due to stability.

380mm is the accepted standard for trials. the BT ninja was 365mm iirc, which is ridiculously short. it isnt all that popular of a frame, so way short isnt necessarily better. but you never see a trials bike with a 400mm cs, because that is way too long, way too unstable, for rear wheel moves anyways.
manualing is a completely different subject, and everyone know how much harder it is to not loop out when you manual your short cs trials bike versus your regular mtn bike. im not sure what your average mtn bike chainstay length is, im assuming about 410mm, but obviously you want a more compact rear triangle than an average mtn bike.

a longer chainstay in theory would give you more leverage for LARGER gaps. In theory

and a shorter chainstay is easier to control on the rear clearly cuz u are closer to the balance point.

Think about it and its pretty obvious

thanks for the input, in THEORY :ugh:

i say this because there are tons of other factors....bb height being one of them. the stays on the frame im riding now are like 390 or 395 or something but with the bb height they feel pretty dope

Thanks;)
So I would assume that the long and short versions of frames have the same CS length and that it is the bb to head tube length that changes?

thats right.

[nikkocholo]

the shorter the better it is to balance on the rear...easy to manual hehehe
