I can't say accurately on tt length as I'm 6'4" and so what works for me may not work for you. My Brisa runs about 22in centre to centre and that's pretty sweet.

Gearing is pretty important so I reckon the best way of choosing is to pick your crank length (either 165 or 170, both work well in my experience) and run a road cluster with a 22t or 24t granny ring. That way you can check out how you like different gears for different stuff i.e big rear wheel moves, precise stuff etc. Pick the gear you like best and then run it SS with a tensioner.

Stem length between 90-120mm works for most stock bikes in my experience, I run 90mm but it comes down to personal taste.

You can get away with standard 1.5in rise risers, well I do and I've never found anything I couldn't ride because I didn't have the "right" sort of bars.

The only brake to choose for trials in my mind is a Magura Hydro with some decent pads (Spanish Fly's, Plazmatics or the Koxx pad, whatever it's called). I reckon Magura's are so far ahead of any other brake for trials use, although some people do prefer the feel of a boosted V. Jeff Lenosky rode for years on basic Shimano V's with good pads and a booster. Now he uses Avid mech discs, but he's got freaky levels of skill so maybe don't go on what a pro uses.

The rigid fork you have should be fine to start out on, as long as it's not some suspension corrected one. Nice and low is the way to go for a trials fork.
When you are great, people often mistake candor for arrogance.

try www.observedtrials.net

you want 22-20 for gearing maybe 22-21 or 22-22, unless you get front freewheel cranks. Top tube length? Long. Depending on your style. Trials bikes are measured in WB and bb rise though. (all rear ends are as short as possible)

the type of brakes you use depends on the frame you get.... if it comes with v-brake mounts use v-brakes, just make sure to set them up properly. if your frame has 4 bolt mag mounts use the hydro's. A disc on the front if you want, prolly not the best idea for the rear.

bars- whatever... wide

tt doesnt really matter- find a trials specific frame to learn on, people say longwr wheelbases make things easier (1080, 1100) i duno


and lenoski still uses v's on his trials bike i think
