Ah, thanks for that info Velo! I had it fixed in my head that all MTB had always been 135 and road bikes 130. The OLD of the hardtail frame is 135mm, so must be a 130 exage.
It needs replacement for this reason:
...so I might as well replace it with the correct width.
I'd detected a bit of a lack of love for URT designs, yes...
Given the low cost I don't mind playing with it, and seeing how it behaves. I'm a bit skeptical of people's reasons for disliking them centering around the suspension being inactive when standing. You'd be loading your mass onto the swingarm behind the pivot, but unloading your mass from the half of the bike in front of the pivot. Who knows eh?
This is what I meant earlier about the Icon bars:
Probably saved all of a few tens of grammes keeping them that narrow. Those, combined with the rigid (short & heavy, 420mm, 1.1kg) Marin steel forks it had on it meant a 70deg HA and serious twitchyness - especially with gripshift plus wide-ish grips moving the controls to the middle.
On a different note, I suspect I can think of two things to improve this:
Firstly, despite there being cartridge bearings in there, that bolt had been badgered up seemingly with a rattle gun, and after sorting that out, I think I'd like a nyloc on it!
