Thanks for your thoughts all, a few replies below.
I'm with Drago. Sorting out your brakes is way cheaper than buying another bike. It could be as simple as changing your brake blocks. Try Koolstop pads.
That's part of the problem - I'm already using SwissStops with upgraded Tektro brakes removed from my Boardman in place of the even worse original items!
(snip).., N+1 buy a new bike and enjoy
Wish it was N+1 - I'm having to introduce a strict one in one out rule so the Triban would have to go
Just find a big hill
Location: Felixstowe - as in Suffolk. Hills = yes, big = no
As I said, it's only a consideration at the moment. I'll have to see how much the car's MOT & service set me back and probably see how this winter goes.
