Hey!
Total newb here. I've had my GT Avalanche for about a year, but have been using mainly on the road with road tyres or through the local woods. Decided to chuck my chunky tyres on and have a go off road. Anyway I've been up Rivington the last couple of weekends to try some real montain biking, what a difference! Last week was a real eye opener. Killed me getting up to the Pike , nearly coughed my lungs out! Anyway on the way back down my arms were nearly shaken off, felt like I'd been on a pneumatic drill. My tyres say 40-65 psi, probably were on about 50. This week I dropped it down to 40, but was still pretty rough coming down. Should I try them even softer? |

No.
 Well actually it's nowhere near as simple as that. You can try lowering the pressure but at some point you will either bottom out the tyre on a step and pinch puncture or find the tyre rolls around on the rim during cornering. Try relaxing more especially your grip and shoulders and a suspension upgrade wouldn't go amiss. Alternatively larger tyres may allow you to run a lower pressure and get away with it but a larger tyre may need a wider rim and of course your fork/frame need clearance too. -------------------- Get proper instruction www.mountainbikeinstruction.co.uk

I probably am too stiff, it's all new to me. I just wish I'd gone off road sooner than I have. The thrill of going down quick (quick for me!) is well worth the slog up. I can't wait for my next ride out. |
