I run a freewheel on a fixed thread
If the freewheel has the same chainline as a fixed sprocket, it can't put more stress on the hub thread. Of course it looks frightening having all that unengaged thread on the freewheel body, but it's not doing any harm. Remember, in the olden days our top sprocket was hanging off the threaded part of the hub by about an inch with no support, and we didn't have any trouble.
Pretty much finished tinkering with the town/commuter bike:
Initial impressions was that even though it was back to SS from fixed, I'm still having a fun time on the bike and with this set up I can finally take it around the country lanes without shitting myself.
We had a little bit of an issue with these TRP brake pistons, maybe to lack of attention, but the real reason why the brakes where rubbing was due to the fact they weren't engaging properly and was close to snapping off the old rotors because of this. So I am giving them a longer engagement level on the brakes to see if they piston issue happens again after a month and this will help me decided if I keep them or change.
The Shimano rotors do look super pro and aggressive, performance wise I'm still deciding whether I like them or not due to the fact they feel like they don't stop as quickly as my old disc, but if they stay true and problem free then who am I going to complain I guess.
Anyways, for my everyday bike is pretty much as good as it gets, the final tweak I did was adjusting the seatpost by 10mm to see if this helps me to use my seat bones and possible pedal more smoothly.
