KR-1S.co.uk Forum

O.K. daft question but when i take out my rear wheel can the rear brake caliper be left in place or does it have to be removed first

after you pulled out the spindle, you need to drop the caliper so it's no more on the disc, and then you take out the wheel

Now i have a 520 pitch chain on my bike and is this standard for a KR1S ?

I want to fit a larger rear sprocket for a bit more oomph and looking at a 42/43 rear but needs to be 520 pitch so is this a problem

520 ist standard KR1S and 42/43 rear is not a problem.

Do you have a link for the sprockets Charles as a renthal one is over £30 as thay will have to make a one off

What is a standard rear for the KR1S ?

Standard is 41

sorry, only just seen "while stocks last"

go one thetth down on the front, has about the same result, but saves you a new chain

It's for my Marmite Hybrid and it has an expensive offset front sprocket fitted
The chain adjustment is right at the back of the adjusters and i checked today and reckon there is enough room for 3 up on the back
