What kinds of derailleurs/cassettes work best?
Trials rarely require gear shifting. Usually, most of stock riders ride with 22t in the front and 18 or 19t in the back. That’s why completely specialized trials machines (ie. mods) are single speed (they use other chainwheel sizes, but same ratio). So basically, you wouldn’t need a derailleur at all, if there wasn’t for a fact that it’s: a) simpler to have it on a stock, b) it comes in handy when cruising the town (uphills/downhills), c) you can fine adjust your power when trying different moves. So, now that you know the story behind it, I’ll tell you how most of the trials bikes are configured: we use 22t chainwheel on the crankset (bigger wheels removed), and usually have a 5-9 speed cassettes. Those are usually road cassettes, because they have smaller gear range (e.g. 12-22, or 11-23) comparing to MTB (biggest gear has more that 30t); why smaller range is a good thing, I’ll tell you in a second. If you use Shimano mtb cassette, you probably won’t have any trouble switching to a r
