BBN Posted March 18, 2010 Share Two questions; What are jockey wheels? How do you work out the gear ratio? I see a lot of talk about 32/44 etc and do not have clue, is it the numbe rof teeth? Link to comment Share on other sites More sharing options...
Greg Squires Posted March 18, 2010 Share Jockey wheels are the little wheels in your deraileur. What you are talking about are blades. They don't kill vampires. Blades are the gears at the front. 32/44 are the teeth they have. Once again not for vampires. The less teeth the easier the gear. The more teeth the harder the gear.

Sammajoor Posted March 18, 2010 Share Jockey wheels are the little wheels inside your rear Derailleur, Your rear cassette has 9-10 or 11 sets of gears, depending on your choice of groupset. Each of those gears has a number of teeth. Your crank in the front has two chain rings also with teeth on them. You also get two types of cranks a compact and a standard crank. A compact crank normally has a 34 - 50 chainring and a standard has a 39 - 53 chainring, but people have been known to fit a 54 or even a 55 as the big chainring. A ratio of 23 - 39 will then mean that the rider is riding a ratio of 23 teeth on the back cassette and a 39 chainring on the front. A 32 - 44, will most likely be a MTB ratio as MTB's have different ratios. I hope this answers your question When they then Link to comment Share on other sites More sharing options...
Thumper Posted March 18, 2010 Share They are the 2 "cogs" in your rear derailleur that guide the chain. They dont affact your gear ratio, that is determined by the number of teeth on your front balde and rear cassette Link to comment Share on other sites More sharing options...

Greg Squires Posted March 18, 2010 Share The easiest way to learn is to ask. Remember to state if it is for MTB or Road. They are pretty dofferent. Everyone who does their own work on their own bikes had to learn someway. Me mostly by expensive mistakes. Link to comment Share on other sites More sharing options...
BBN Posted March 18, 2010 Share And it seems to be easy to make expensive mistakes. My god, some of this stuff is expensive! 23K for a set of MTB wheels, not mine unfortunately! Link to comment Share on other sites More sharing options...
