I'm not going to bother with the
Evans service. Their mechanics are mainly rubbish. The assembly of my Solo was late & shoddy. I've put it right, and just accepted that I got a good price anyway, so no problem.
Niggles with mine:
I have a mudguard rub at the front, because the bracket on the guard is too long for the fork.
Um... that's it ;D
I had the same problem with mine. to fix it you need to loosed the small nuts on the mounts and also the brake (from behind the fork). You can then lift the bracket up over the headset shell giving you more clearance.
You'll then need to bend the top of the bracket forward otherwise it will rub against the headset shell. Tighten all the bolts and you shouldn't get any more rubbing.
Don't do what the "engineer" in my Evans did and just lift the guard up so the mounting bracket jams into the headset
I've done similar upgrades to my Solo as other people. Saddle replaced with a Specialized GB Avatar which I already had, seatpost wasn't long enough so replaced it with a carbon one I found on sale for £18, pedals replaced for SPDs, bar tape replaced for padded Spec tape (also already had lying around), shorter stem fitted, tyres upgrades to Vitoria Rubinos in red and rack fitted for panniers.
Next upgrades will be the freewheel. Mines a bit noisy, could just use some new grease but I don't like the deadspots on it. Then the brake calipers, possibly for some Dia Compe ones in red for some added bling
I recently rode mine to Amsterdam and back and it was very comfortable.
