My chainring is aligned with my 6th gear. Honestly though, I wouldn't worry about it... 9/10spd chains have a pretty wide range of lateral movement so it's more or less a a non-issue.

yea it bolts right on the crank arm, but adding or removing spacers to the cranks move the ring inner or further out, that is what im referring to

all right but, what im supposed to align the chainring with?
I think you're overthinking it... it's really not that hard on a single ring DH bike. Back in the day when some DH bikes had 73mm BB and 150mm rear ends it was a problem but now that everything is running an 83mm BB with a 150mm rear end you'd almost have to try to screw it up.

ok, im asking because i have never built a bike from scratch, i always bought complete bikes that came built (im not saying that pre-built bikes have a correct chainline) but i never cared, now that im building mine, i dont want to mess up in anything Smile

right i think this needs discussion!
sram made 9 speed which was good then up to 10 speed which is alright but then monster specialized ran an awesome micro gearing 6 speed thing that would be awesome to have!
i hate my 10 speed that i upgraded to ghosts all the time and have the best cables etc and setup and maintained at the shop often

i think the market needs a 6 speed drivetrain just for dh and ds type usage, which will allow solid shifts each time, design of stronger chains not these skinny arsed 10sp ones,
less is more i think!Salute

I still like a good old fashion 9 speed system, haven't tried 10 speed though so can't really say, but I think 6 speed would be too little.

i mean for a racing point of view, racing products for racers,
don't know about you but i have been racing dh for 6 years so far and i think there is a need for it at the high level we now are at for dh racing

limit screw. spacers, if need be, back plate. there's literally nothing wrong with a skinny chain. They can make them stronger for sure, but that adds weight...

now that i went from a 38 to a 34 ring i think i will be going from 9V to 7V or 6V as im getting clearance and i dont use the highest gears often
