i need a trials uni with splined cranks, 2.5 tire , yuni frame ,miyata seat.
i think your being a bit to picky:)
Unicycle.com has several unicycles that may fit that condition, but they put KH seats on all trials unicycles. You may be able to order one from them with a torker LX seat on it instead, but I don’t know if they have the same bolt patterns…
