Long Term Long Teng update:
Currently at 4,970KM, will surpass 5000KM after a short afternoon spin tomorrow.
No problems at all with the bike since I built it up. I love it.
A few things I have changed:
Swapped to an ENVE Selle Italia Boost SLR 130, which fits me better and which, when slammed forward, is helping me rotate into and sustain the aero hoods position.
Swapped the 35mm Michelin Pro5 (37mm WAM) tires for 32mm Continental GP5000 S TR (33mm WAM). The fat tires were comfy and fast, but I am happy to drop the weight ~150g, and I think the GPs fit the bike better without much compromise. I am back on shit roads in New England, though, so I don't think I can afford to go skinnier. I think, despite the generous tire clearance, that the bike probably fits 30mm tires best--is designed around 28-30mm. I was getting toe overlap on the 35mm Michelins, and I think for big tires a slightly larger BB drop would be welcome.
I just got 165 cranks but haven't put them on yet. I'm on 170 currently but want to keep optimizing the trendy progressive fit and also open up the hip a bit as I'm dealing with some chronic hip mobility issues on one side from an old hip flexor injury on the squash court some 8 years ago
