isitafox Posted July 19, 2013 Report Share Posted July 19, 2013 Quick geometry based question, how does the chainstay length affect the way a bike rides? Quote Link to comment Share on other sites More sharing options...
Azarathal Posted July 19, 2013 Report Share Posted July 19, 2013 Short Cs = flicky, long Cs = tgs barge Quote Link to comment Share on other sites More sharing options...
bing Posted July 19, 2013 Report Share Posted July 19, 2013 Shorter chain stays, CoG is closer the back wheel, makes it easier to hop about when up on the rear, but less able to do spinney stuff. Longer, the opposite. Quote Link to comment Share on other sites More sharing options...
Ali C Posted July 19, 2013 Report Share Posted July 19, 2013 Shorter chain stays, CoG is closer the back wheel, makes it easier to hop about when up on the rear, but less able to do spinney stuff. Longer, the opposite. not true, shorter stays = more spinny happiness. They also make hops easier but potentially sacrifice max height by a little.

bing Posted July 19, 2013 Report Share Posted July 19, 2013 I thought having the cog as close to the middle as possible would have made spinny stuff easier, as it would be on the central axis so to speak. I'm probably wrong though Quote Link to comment Share on other sites More sharing options...
Ali C Posted July 19, 2013 Report Share Posted July 19, 2013 Spins are driven from the rear wheel in proper hops (IE non english hops) so the closer the bb is the rear hub the faster the bike reacts and the easier spins will be. There is a compromise though as too close and the bike becomes really nervous and harder to control. Quote Link to comment Share on other sites More sharing options...
isitafox Posted July 19, 2013 Author Report Share Posted July 19, 2013 Cheers for the info lads, was for the Marino so no need for spinny ability, wheel is now set at 368mm as opposed to 357mm Quote Link to comment Share on other sites More sharing options...
LEON Posted July 19, 2013 Report Share Posted July 19, 2013 I don't think long stays are good for anything but hill climbing or drag racing. But you can go TOO short, mine are about 369 & it feels about right. Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted July 19, 2013 Report Share Posted July 19, 2013 (edited) 358 here,pretty good.but to be fair,reach and bb height play together with cs lenght and shouldnt be looked at as an isolated measurement old frame had 4mm longer cs (barely noticable for me)and the rest of the geo was totally different,so that took a larger part of the feeling the new one had...

isitafox Posted July 19, 2013 Author Report Share Posted July 19, 2013 Was just asking as I could have butchered my JAF rotor to get my wheel sat where it originally should have been (357) but I didn't fancy that so wanted to see what the effect would be with me moving further back down the dropout.
