ive got a kona mate and it just doesnt seem 100% (took me a lot of playing with to get right) - but i think thats because i brought it from jejames's, a bloody rubbish shop if your young imo

the bloke didnt beleive what size chain had on a bmx and are just generally unhelpful.

back to the bike - it has hydralic brakes which theyd spilt fluid from and damaged the lever, the back brake was absolute boloocks and they had to change it, didnt tell me how to pump up forks (its easy i know but really wasnt helpful when i was spending 500+ on a bike) and the front pads wore out within a month because they were fitted wrong

find a bike shop you like or get on with a person in and you wil get a better bike imo
