Chainring teeth numbers

[Rusty 73]

Currently running a 44t, if I were to change to a 45 or 46 do l ave to change anything else like the chain. Sorry to ask, answer is probably obvious, but not sure

What are you running on the rear buddy?

What frame is it?

How much room do you have in the rear drops?

It should be just a case of adding 3 or four links to the chain. If your axle sits near the end of the drops, you may only need a couple if you have the room to slam it. You will need to ensure your calliper is suitable for that too, arm length wise.

All depends where your wheel is in the dropouts, normally get away with the same chain with 1 tooth larger providing the wheel is in the middle of the dropout
