Sugino RD2 chainline
so here's a new one for ya'll... and yes that is sarcasm you detect...
i recently bought a track frame with a sugino RD2 touring crank (has bolts on the inside for the granny gear) attached to what i believe to be a sugino 103 BB. this combination is reported to give one a 45mm chainline when the chain ring is on the outside of the spider (as it currently is). i'm running this with a formula track hub, dura ace cog + lock ring which i assume to give me a chain line of ~42mm. 3mm difference is not something i'm really into, and while the chain line is pretty quiet, it's not that morbid silence i demand. so for starters, i tried moving the chain ring (48t, 1/8") to the inside of the spider, but no such luck: the chain ring rubs against the chain stays. Ideally, i'd like a perfectly straight chain line, but i'm willing to settle for 1-2mm difference between the ring and the cog. options for achieving this include a 107mm BB with the chainring on the inside of the spider, redishing the wheel to change the chainline (would really rather avoid this), spacing the rear sprocket (is that a terrible idea?), or perhaps just a smaller chainring (44t? 42t? will this provide enough chain stay clearance?) I'm willing to shell out some $$ to make this happen (perhaps for a new BB) but i'd like to keep the process relatively inexpensive. So! What do ya'll think is the best option? anything i've overlooked that could solve this easily? thoughts? opinions? **** talking cause it's moronic for the RD2 to have a 45mm chain line? thanks for your help!:D |
RD = road double. It's not supposed to have a 42mm chainline.
I started a similar thread asking similar questions that is still active. |
Has anyone really been far as decided to use even go want to do look more like?

Ha!

Don't listen to that troll, Scrodzilla. He was just trying to make fun of your post. Your post was a legitimate question.

That seems like a lot of effort just to make fun of my post. Some people must really not have better things to do. I guess I fell for it, huh?
ADSR - blowing my mind. |
damn my head hurts :)
