A Guide To Gears

[Joey Shabadoo]

Anyone written one? Although I've been cycling for a wee while now, I get totally confused when folk go on about 105's, Campagnolas, SRAMs, Soras etc. What difference does the toothing on rear cassettes make? What advantages do you gain by trading up - indeed which way is up?

I did a forum search and came up blank - am I just being dimmer than usual? Is there a thread on this already?

Sheldon Brown has more information than you could possibly want on this (and indeed, just about any other) topic:

Shimano, SRAM and Campagnolo are different component manufacturers.

105 and Sora are two of Shimanos product ranges, used to classify differences in weight and performance. The hierarchy generally goes Sora->Tiagra->105->Ultegra->Dura-Ace
