As someone who relies heavily on his bike to commute, I was really pleased to have walked into Trek at Battersea Reach to fix my broken chain and gears on my bike. The Team at Trek really know what they are doing. Not only did I get my bike back in time for my next long commute, given their knowledge, I was able to pick their brains about my bike - what they knew about the make and model, the longevity of some of the parts and when I should look at changing some of them and more. I highly recommend them.
