Can someone remind me what the point of E-stay was? Is it just to stop chain bashing chainstay and/or stop chain suck?

A mate of mine has an E-stay Al-Mega with early Rock Shox... the frame has cracked, just like everyone else's Al-Mega as far as I can tell. Don't rate 'em myself.


Chainsuck would be one of the reasons.
An e-stay also allows you to remove the chain without having to take it apart (very handy if you're considering belt drive).
Also, normal bikes need to have a certain chainstay length (distance between BB and rear axle) because the chainstay tubes need to clear both the tyre and the crankset. An e-stay doesn't have this problem, so you can shorten the chainstay length up to the point where the tyre nearly touches the seat tube. That makes for quicker handling and better climbing capability.

I think the latter point regarding shortened wheelbase was the main reason. Some types such as Alpinestars have the lower portion of the seat tube kinked forward to increase clearance.

I believe the main reasons were to eliminate chainsuck and to allow much greater tyre clearance....


Hmm you would think so but in the case of Alpinestar the front mech put paid to any tyre clearance i thought it was to enable the rear wheel to sit closer to the frame to aid hill climbing or was that just a happy coincidence ?? :)

whatever the reason was, to eliminate chainsuck + shorter wheelbase, both is correct, ecs bikes still have the special " look "... :D

It was to give you something to bank your ankles on.
