Greasing a roller brake in a difficult spot!

I have used Lucas "Red & Tacky" which is the same grease I used in my BBSHD Main gears. It is great with heat and so far 1118km is working well.

What is the model of this bike?

Is it possible to change chainrings to bigger on Shimano FC-MT500-B2 (2x10, 36T-26T)?

Maybe It’s a 96mm BCD chainring so you might be able to purchase a compatible part e.g Shimano XT M782 40t 96mm 10-Speed. A third party 96mm ring will also be fine. You will be looking for 2x10 96BCD ...

Chain broke after link removal - what to blame (with photos)

HELP with derailleur upgrade question

You'll need any 8 speed derailleur from Shimano or another manufacturer. As a rule of thumb, the differences between road and MTB, and differnet maker's designs only start to become an issue at 10 ...

Claris crankset compatibility with 105 components

If you mean to say you're putting on an 11-speed STI, no, it will not work with your 8-speed FD. Not even a little bit. Shimano road 11 front derailleur cable pull is too different from previous ...

I think you could give it a try. Check to see how the 11-speed chain engages the Claris chainrings. Also check to see if the 11-speed chain will slip between the two chainrings. If it engages well and ...
