What is the difference between street & trials uni?

KH drilled rims and the Nimbus trials rim (old KH) are the same strength. I think most street riders use a trials, mostly w/ shorter cranks. Those who want a stronger wheel can use 13G or even 12 Gauge spokes or a solid Try-All rim (I’d do the stronger spokes).

Some street riders prefer larger wheels 24, 26 or even 36" (check out Brian O’s 36er street/Muni vid).

Check the trading post forum.
New, you are looking at $300 (other colors are a bit more $), although I’d recomend ubgrading the cranks for $25.
