1x9. What size chainring?

Grannygrinder · Mar 12, 2011

I'm thinking 32?
I have 32 and 36 unramped rings, so sods law dictates that i'll be needing a 34 :?

All help greatfully recieved

Why not run a 32 and a 38, no front mech and just change manually? :?

Seeing as you're running a 9 speed block it's not going to make a huge difference in normal riding.. as the block should give you a good range of ratios

IMHO, if you're doing more climbing go for the 32, and if you're doing more downhilling go for the 38.... simples

what ratio cassette? if low like 11-28 the go for a 32 if a big ol 11-34 then try a 36

On my 1 x 7 I run a 34 at the front and 11-23 at the back. I do spin out occasionally downhill but manage fine in terms of climbing etc. Though in truth I find my self not changing gear too often and think of it as a single speed with a safety clause in case of hills.

36 front with 12-31/2 (?) works fine on the North Downs. Dunno bout Wales though...

I've got an 11-34 cassette.
So 32 front and 34 rear is slightly better than 1-1 which is good for the uphills

and 32 front and 11 rear should be fine downhill unless its steep, in which case i'll have the brakes on anyway

Sound about right? I'm thinking 36 front will make the uphill much harder

:?

36!

i run 36x12-26
works lovely
if you find it hard to begin with, you will get used to it

Will stick with 36 for the time being, seeing as thats what i fitted first as i couldn't find the 32 at the time
