Nick, as in Nick from Hastings Cycles? Don't touch with a bargepole... When I first got into trials, he "advised" me on my first bike.
Know what I ended up with?
An X-Tort, with two V brakes, DP2000 rims (those real skinny aerodynamic things that are weaker than a cardboard box) and deore hubs (half a pedal, SNAP!) the best part he sold me was the PIG headset. The rest was rubbish and had to be replaced...
Sorry Nick, but it's true...
P.S Python's are the only mod bike i'd actually ride... but then i'm 6'2" so I look silly on such a small bike... Oh, i'm almost 21 as well so I feel silly on a 20"...
