Yeah, I have a boardman bike (CBoardman, MTBHT 2010), it's a great bike, but after only 6 months I was coming down a steep hill at around 30-40MPH with my friend, and the bearings in my back wheel got tight and snapped the rear quick release axel. Therefore the rear wheel then came off and over took me, leaving me to coast/slide to a halt.
When I took it back to Halfrauds, they then charged my dad around £160 for te majority of the rear components to be replaced!
Around another 6 months on, and I'm having trouble again, my rear wheel started to wobbly. So I took it in, he said it'll be fine to ride until the service in 2 weeks! So I rode it, brought it in and I was then told that the bearings had collapsed. Paid £16 for them to be replaced. Started riding again, same problem, tool it back in, needed a new hub, how did the mechanic not see that in the first place?!?!?!
Still an ongoing dispute...
