My Kona has been blinged to death, the only parts left are the frame and forks (rigid). But that was done over time when parts had worn out and were replaced with the best I could afford. It has had a few bar and stem combos over the last 18 months, I’m still not convinced, but they were bought off the classifieds, so the parts bin is looking very health with bling parts.
My Sanderson SS was a custom build so had all the bling from the beginning. It’s had a couple of bits and bobs, things that I wasn’t happy with in hindsight and a couple of ratio changes for different times of the year.
Life’s too short to ride crap bikes. 😉
OP. To replace your Halifax Filing Cabinet will cost you £2.5k ish? Or as you say £600 for the parts to rejuvenate it. No brainer IMO.
