[rh.plus.peter]

Hallo everyone! I am new to retrobike.co.uk but since it is getting harder to find old school parts I have registered today!

I am looking for Roox ChainDog chain guide (the upper one, clamp style). Same like this one: https://products.mtbr.com/product/drivetrain/chain-accessories/roox/chaindog.html

Cheers,
Peter
