I had an 08 Sx Trail with 2.35 Hi Rollers Soft Compound, VAn 36s and a twin ring, had to up the chainring as was spinning pout too much otherwise. Changed forks to 66s and that was that. Thought it was great till i tried a 140mm Lapierre, I always wondered why I was soo slow on the SX, get a Heckler, or Intense SS, or Lapierre Spicy? Orange Alpine 160?
