This is the really simple part. The pricing is fixed. There is no set price for a 'service', which can especially frustrating if your bike is already in pretty good condition. I'll look at what actually needs attention, give you a time scale and cost for any parts then get it done, simple. You'll be back on the road, gravel or throwing yourself helplessly down a mountain as soon as possible.
The labour charge is £60 an hour (plus any parts needed)
