OK, before you blast me, I have done a search and I have looked all thru the manual and can't find the answer.
What size nuts are holding the rear tire? They are different size on each side. They are bigger than a 19 mm. I think maybe a 23 and a 29???
Need to adjust the chain tension.
Thanks

 

It never occured to you to take a caliper and measure them?

The answer is 22 & 27 mm wrenches...

 

If I had one I could have, but I don't.

Thanks Tweety for the info. I didn't want to have to go buy sockets or wrenches from 20mm up to 30mm just for two nuts.

 

one nut, one bolt
