Just before Cube roundabout, pull into the sliproad before coming from Center, my husband got a mountain bike for 260QR brand new and it's still going 3 years on!
There is a strip of shops, drive around the rounbout a few times and you will see. My H also had a problem with a buckled wheel, his fault a year later, and they fixed it for free. Very nice men. PM me for details, he is out at the mo.
