I bought a Jett 143 for my moutain bike, which after breaking it in seemed to be ok, so I bought one for my rockhopper that I'm now using to commute and on the turbo (put on some rigid forks and skinny slicks).  The one on my rockhopper, gives me no end of grief and I keep developing big lumps which end up so sore that I can't pedal anymore sitting down. 

I originally got measured in Edinburgh cycles, however I went into Evans last week and got re measured.  Apparently I'm not a 143, I'm a 130.  However the guy was really helpful and said that if it doesn't cause me as much pain on my xc bike then it could just be the set up.  I'm gonna get on with it this afternoon and then give it a try on the turbo, but he said to measure from the middle of the end of the stem to the tip of the saddle on my xc bike and then move the one on my rockhopper to the same distance away.  Also to check that when sittin on the bike with the pedals level that from my knee to my heel should be straight.   I'll let you know how I get on, but if it doesn't work, I'll be selling a Jett 143
