Halfords own Boardman. I have had three Boardman bikes, currently an ADV, I know the mechanics at the Guiseley shop by name and have nothing but praise for how I have been dealt with there over the last decade and more. I cannot comment as favourably on the service in other Halfords branches.
I take the Bianchi to Woodrups in Kirkstall who specialise in Bianchi (and usually have around 20 bikes on display in the windows) and can work on Campagnolo.
