Hi,
I had a Boardman Carbon (c9 I think) for three years, did about 15000 miles on it then hassle with BB coming loose in frame, and rims wearing out twice. Good bike tho.
Got a Ribble to replace it 30 months ago.Ribble 872
I got the cheaper Tiagra, cable disc version. So impressed. slightly heavier, but just feels better/stiffer. 13000 miles in now and only replaced pads a few times and the chain once, and a snapped brake cable (That was fun, downhill versus a John Deere coming up!!) Tyres swopped to GP5000 for normal use.
(even got a set of spare wheels for it now fitted with WTB Exposure 30s, that fit the frame easily, use for bike packing/mild off road/gravel
Can’t fault it apart from long lead time.
