In defence of Boardman,,, I’m a proper chunker and my team carbon has done a few thousand miles across some awful Scottish roads with no issues at all, my local bike shop has done some work on it, and never complained about any nonsense of soft metals or poor carbon.
For the money the kit is very good value, get over the “oh it’s a Boardman” snobbery, and sling your leg over one. You’ll get a lot more bike for your money than with a lot of other brands.
Let’s be honest, its not a BMC or a Storck quality frame, but are you seriously going to do the mileage that justifies that expense, and is your riding standard high enough to feel the difference?
