i have a 2001 Sugar 1 that i love. problem is the first owner didnt love it quite as much as i do and never maintained it even though he was racing it and riding it like a downhill bike. the cassette was really loud so i figured it needed a little lubrication before it trashed the internals. so i got the thing apart and its not like any other engagement system i've ever seen. rather ingenious actually. two identical peices (idk what they are called so i'll call them thingers) nest together and one splines into the gear cluster and the other splines into the hub. there is a spring between the hub bearing and the thinger. that causes the thinger to reciprocate as the teeth slide along the teeth of the other thinger in the cluster.
i'll get pics if i can. so i took it all apart and checked all the bearings for wear and some are a little wobbly but no huge problems. i also cleaned the whole gear cluster cuz it had obviously never been cleaned. i put it all back together and now when i turn the driver back its really tough and i can tell its from the cluster going side to side rather than the thinger in the hub reciprocating. i have mostly figured its because they are pushed together too close and the spacer that goes in between the hub bearing and the driver bearings seems too short by only a little bit. i put a rubber band on the axle in between the spacer and the bearing to move it out a little and hopefully fix the problem. now the thingers aren't mashing too close together and it sounds right but when i put the wheel back in the dropouts and tighten the skewer it completely locks the cassette and does not coast.
does anybody with this wheelset and this bike have experiance with this problem? how do i fix it because spring is crawling up quick and i cant afford a new hub.
