Overall fairly good experiences; bought cycling clothes etc from there in the sales and you can pick up some excellent deals, especially with BC discount, got a Sportful Gruppetto Team jersey for £30 for example.
Bought my Boardman Team Carbon from there too; staff were very helpful. BUT...the front derailleur was never right for some reason, they'd fix and then it would revert back to not changing from rear to front cog after about 2 weeks. Took it to a repair shop who fitted a new cable and it's now good as gold, so guessing that it wasn't fitted properly originally.
All in all, I'd say they're a good store - would buy stuff from there before
Evans any day of the week.
