Changing from 12-36 to 11-32 : Chain or mech adjustment

tbikeradar

Hi everyone,

Just wanted a bit advice on the above.

I am riding a lot of flat stuff and dont need a 12-36 rear cassette:

My current setup is 39/26 at front and 12-36 rear.

I want to go 39/36 front and 11-32 rear.

Should I shorten my chain accordingly or can I adjust the rear mech to take up the slack?

Thanks,

tBike..

Remeasure the chain. Though ideally you should use a new one.

You can't go 39/36 front.

Hi, I meant 39/26 up front.

Ok I will re-measure. Chain is hardly used so should not impact on wear.

thanks Sonic

Rear mech will need some adjustment, indexing may need tweaking (unlikely) but you will need to adjust the b-screw to move the upper jockey closer to the largest sprocket.

Thanks for all your advice, one quick last question...

Is it ok to use my existing Sram XX long cage mech with this setup:

39/26 front and 11-32 rear?

Thanks

Yes..... Although a medium would be slightly better in terms of lower chain run angle and ground clearance.
