Far better idea to just bite the bullet and buy new. Technology moves on so quickly these days, so buy new to get the best stuff.
I’d also forget about the ‘bike for life’ thing unless you want to be riding the equivalent of an Austin Allegro in 10 years time.
10 speed DA
Handbuilt wheels, stans rims, Ultremo ZX tyres
PX Forged brakes
FSA carbon chainset
Ritchey WCS bar stem, lizard skin DSP tape
Canyon VCLS post, Selle italia saddle
There’s really nothing on it that I’d immediately think to replace apart form the rather battered looking frame.
(what’s wrong with a planet X pro-carbon for £300?)
Nothing at all (well I’ve never ridden one, it might be horrible for all i know), but they’ve never really caught my imagination. Ditto Ribble. The closest I’ve seen/found to something fitting the bill is the Dolan Ares.
