long time trials rider here
(unfortunatelly it doesnt reflect my riding)
At first. forget 32 t chainring.
In ninetees there were not trials specific brands for components.
and those few that were made for trials sucked
So basically it was up for anybody to choose the mix of mtb and DH components that worked for him.
Monty and maybe Megamo (the only companies serious about trials bitd) made trials rims that were wider. 39mm for the rear one. But im afraid Pace wouldnt accept it. In that case those first CD Mavic dh rims were popular (forgot the number 521??).
In the back you need road derailleur and cassette. anything you like.
Up front: small chainring 22t and bashguare instead of the big one.
at that time there were some companies making bashguards..or homemede stuff like i did.
rear hub: the only one criterion: number of clicks.
Since 97 there has been one standard: Chris king
before that: anything you found that was better than shimanos 16 clics..
saddle: your choice. Smaller and lighter the better.
Tires: everybodys call. Big in the back but not too heavy. soft compound prefered. upfront: standard xc tire.
Bars: 68-72cm wide dh risers
pedals: bmx/DH platforms or VP double cage if you were more BIU type
What year that PACE frame is exactly?
here are my trials bikes from the past up till now.
in last decade trials has made a big departure from all bike disciplines in terms of bike geomery and parts.
PACE was my dream frame. cool, radical, different..
Its a pitty that (unlike with MTB) once you try modern trial frame, old ones r unridable
