I ordered a new front disc caliper from a bike shop over the web for
£20. When it arrived it didn't fit the mount on my forks and when I
queried this with the shop they said I'd ordered the wrong version
(even though they only had a post mount version) and I'd have to buy an
adaptor off them for £12. I also asked why the adaptor was shown in
the picture but they said it didn't come with the product.
Slightly annoyed at a small lump of metal with 4 holes costing £12, I
went to the local, well established bike shop in town who said they
didn't have any but could order one. It would cost £20 for the
adaptor and I would have to buy a new, larger disc to get it to work or
alternatively I could buy a set of hydraulic brakes off them for £80.
Tried another smaller bike shop in town and they had no idea what I was
going on about.
As last resort I tried Halfords. The young lad who was new had a look
through his cabinet of parts and found one, but it would require a
bigger disc. I showed him some of the display bikes which had a
different adaptor which allowed smaller discs to be used, he went out
in the back and came out with one such adaptor and sold it me as 'stock
disposal' for £3!
I know a lot of people don't like Halfords, and every bike I've had off
them has required a fair bit of fiddling to get it working how I like
it but Loughborough Halfords get my vote for customer service and value
this time!
