Hey,

being only new to MTB and doing the usual Dam, falls etc trails I generally run my tyres at 40psi, talking to a bloke on the weekend said that I should be running them at max 25-30psi ? seems to low but whats the G.O?

Hi all. Was hoping someone mechanically experienced might be able to help me with my move to a shorter cage rear derailleur and quieter drive train. I've got a 2008 Giant Reign 1 which i've modified to have just a single 32T chain ring up front and still the stock standard 11-34T cassette at rear. The stock standard long cage SRAM x9 rear mech is still there but I'm looking to buy a small or medium cage SRAM x9 for a tighter ride. Can i go to small? Thanks for any help. Happy trails.

Just wondering if anyone has experienced any problems with the Scott Spark frames? I purchased a Spark 50 about 6 months ago and the rear triangle cracked completely through on the bottom stay close to the main frame. Had the rear triangle replaced and frame upgraded to a Spark 40. Have ridden the bike maybe half dozen times around manly Dam Terry Hills etc. Last weekend the frame cracked in exactly the same place on the rear triangle after about the same amount of riding as the first round.

I'm not really happy with the performance of the shifting (not accurate and a bit slow) on my bike and I am wondering where to start. I imagine the components on it are not crash hot and I was thinking of replacing my rear derailleur with something a bit better. The current derailleur is a shimano deore that came standard on my GT avalanche 2.0. My shifters are alivio but not sure its worth replacing those just yet. I have an 8 speed shimano cassette so l want to make sure that if I replace the derailleur it will suit my current setup.
