Hi im new to trials, live in New Zealand,had the bike over a year, did a three day ride called the tussock buster. As soon as i got back home i wanted to check the front wheel out as it sort of locked up and threw me. First i noticed the axle/wheel spacer was showing witness marks of being off centre, i undid the fork clamp and axle and the wheel dropped slightly with a clunk? I was expecting some sort of breakage, but worse the axle was 20mm diameter and the 6905 bearing had inner track inner diameter of 25mm. No bushes just an aluminium washer either side of wheel relying on friction on the bearing inner track to hold the wheel in place, with 5mm clearance for the axle? Has anyone had this, the bike was brand new, the dealer doesnt know what and has stopped sending emails. Is there someone out there had thisproblem, the last thing the dealer said was it may have been a disgruntled employee as gasgas was going under. Anyone got help please
