@Glen.Coutts I’m curious about your assessment of the Gen4 Domane… Am I correct in thinking you had a Gen 3 Domane previously, with the Front Isospeed?
If so, I’m wondering about your experience with the new frame that does not have front isospeed?
My 2020 SLR6 has been a fabulous bike, albeit with an endless chase of creak noises, and with the front isospeed replaced having come totally unthreaded leaving the headset/fork crazy loose (good thing I caught it before going out to ride the day that it was fully loose) at less than 6 months of riding, and replaced again another year and half later because it was creaking again, bearings were badly rough on one side.
So now I’m working with Trek via my Trek bike shop again due to seeing that the mounting holes are misaligned in the front of the frame (they just don’t line up straight across the head tube), forcing the isospeed decoupler to have heavy binding stress put on it when it is secured in the frame. That’s been the trouble since day one, explaining the failing bearings always only on one side, and possibly explaining the original loosening of the decoupler. Not sure why the previous tech work didn’t note that binding stress because it was super obvious when I did this myself, following the service manual. Maybe they saw it and just didn’t bother to tell me; maybe they didn’t check that the decoupler moved freely after install, as directed in service manual.
In any case, I expect Trek to do the right thing here and replace the frame, which will mean changing to the Gen4 frame you have but in SLR spec. I’m wondering how much I’ll notice the loss of front isospeed, although mine has almost surely never functioned as it designed, because the bearings were always in a bind and restricting motion of the decoupler (except for the first few months of ownership, when the setup was loose and getting looser!)
You obviously love yours as is, so maybe it’s not going to be a big loss anyway, and losing the weight of the mechanism as well as one less thing to maintain is a plus (though they specifically said “no maintenance required” when I bought it. )
I also am considering the Conti 5000 AS TR as my next tires INSTEAD of the 5000 S TR because the tread life has dropped CONSIDERABLY with the TR from the TL that preceeded it, and it’s obvious why. They thinned that tread down too much on the TR model. I’m pretty disgusted at that because the cost is higher than ever, but the wear is probably 2/3 or 3/4 of what it was.
It’s easy for me to believe that they had the AS in mind all along, as basically the exact same thing that the TL used to be, albeit with possible technological improvements that may or may not have been made in creating the TR model. The AS model is pretty much spot on with tread thickness that used to be standard on the TL, which for me was THE TIRE. I never wanted it to change. It held the road better in wet or dry, gave good wear life, and NEVER let me down with flats or failures of any kind (as long as I didn’t let sealant go dry.)
My latest TR tires were worn down close to losing the wear dots by the time I reached 2000 miles, and I’ve pushed them now to almost 2500 miles, but the dots are mere shadows, if that. I’m starting to spin out some even on dry climbs and it’s time to let that tire go, but after getting well over 4000 and even over 5000 miles on previous rear tires of the TL variety, it’s a hard pill to swallow.
(And on front tires, the TL gave me about DOUBLE the life of the rear tires, so yes, close to 10,000 miles. I’m currently at about 4800 miles on the front TR model, the first one on the front, and it has quite a bit of life left.)
Yeah, that’s exactly what my hesitation has been about that device… It might be fine, but I’ve only gotten really frustrated trying to get a tire mounted a very few times, and those a long time ago.
The Bontrager AEOLUS PRO 3V have been very reasonable with the Conti GP series tires, at least for me.
