Chiefgrooveguru, we're in Sheffield now. The riding is much harsher and not quite as convenient to squeeze in. I miss the ability to quickly blast a loop around Stanmer, but the rocky stuff here is refreshing. Sometimes it's like climbing on scree with big square blocks chucked in for fun and the descents don't have much in terms of corners (apart from the built stuff). It's making me consider FS again 😳
I pummelled a bar end cap right into my inner thigh, no riding for a while...
How's life? Which FS did you settle on? Solaris?
The bike I bought six years ago, I'm still using the spokes.
Anyway, in the last year, I guess I've done
new tyres on the regular wheels, & got a 'spare' set with DH tyres
brake swap
new seatpost (bent the old one)
If you change the frame then is it really the same bike? In my mind stripping the components from one frame to another means you have built a different bike
To a certain extent I agree but for some reason I still see mine as the same bike but with a different frame as everything else has stayed the same. Its different but not different enough for it to seem like a different bike. I suppose if I had changed the forks and wheels at the same time it would feel like a totally different bike, but as its just one component it feels like an evolution. It's a strange one.
Also forgot that I changed my M4's with a Mini lever (rubbish by the way) for Shimano Deore brakes.
The big bike also had new wheels earlier in the year...I swapped my NS Bikes hubs on XM321's for Easton Havoc's and I finally went tubeless (swapped my Maxxis Minion/High Roller set up for Hans Dampfs).
I've clearly spent far too much money this year in bikes! But at least I've ridden loads.
For my 29er, a bit - it's gone 1x10 is the main change. New saddle too.

CX bike - new frame/fork so quite a big change I guess.

For my other bikes, no significant changes
In the main there's nothing of note but then this:
