Smooth

Bought a pair of 10 teeth cogs to replace jockey wheels on a 1990's long cage sachs derailleur. Selection of bushes meant that I could match the wheel width.However, I had to gently ream out bush to fit locating pips on the back face of cage. Cogs run smoothly but seem to have more rolling resistance than the old cogs. Perhaps this will improve as the drive train beds in. Tredz delivery performance impeccable as ever.

Smooth

Have only had these a short time, but so far my transmission is running nice and smooth. Bearings appear to be of a high quality, much better than the stock Shimano ones. I opened them up and packed them with a bit of extra greece before fitting, as you do.

New life into old derailleur

These were easy to fit and seem pretty robust. I've fitted them on a friend's bike. Time will tell how well they last. Fitting them did mean she got to keep here classic suntour vgt. At £8 you cannae got far wrong.

Derailleur/Mech Guide

What are derailleurs and mechs?

Derailleurs and mechs are two names for the same thing – the parts of your drive train that move the chain between chainrings for the front derailleur/mech and between the cassette cogs for the rear derailleur/mech.

Who needs a derailleur or mech?

Not all bikes have derailleurs, but if your bike has conventional gearing rather than singlespeed or hub gears, you will have at least a rear derailleur. These parts are exposed and somewhat vulnerable to damage, so you may need to replace them if this happens.

What are the choices?

Your choice will largely depend on what is compatible with the rest of your drivetrain, but there are different options for road and mountain bike, by the big three manufacturers, Shimano, SRAM and Campagnolo.

What should I buy with them?

If you’re replacing a front or rear mech, you may need to replace some other parts of your drivetrain as well, for compatibility or because you want them to wear together. These might include the chainrings, rear cassette or chain.

Anything else?

It’s not just compatibility with your other components you need to consider with a mech replacement. Derailleurs also have different fittings for various frame compatibilities, including braze-on fittings and a bolt-on collar.
