So an update on the frame/bike. I tried it with a 130mm fox fork but didnt like it when riding fast cross-country tracks, its too light upfront making it over-steer and loosing traction easy. So I went back to my 100mm SID XX. Also changed the Next SL cranks (they had started to delaminate) and basially the whole drivetrain to Sram GX except rear deraullier and shifter (still XX1) . Been playing around with the front/rear suspension settings alot and finally feel that its tuned as I want it, using the whole travel if needed but firm enough to pedal well without locking. Changed the tires from Rocket Ron to Maxxis Ikon 3C EXO 2.9 * 2-2 since the Rocket Rons sidewalls are way to fragile for my rocky trails. Had some issues with a creaking BB (I thought) and after removing and reinstalling it I finally realized it was actually where the seat connected to the seatpost that made the noise!
Been riding many many hours on the bike and I really love it, best bike I had. Handling is superb and its fast as any hardtail on the flats!
