I finally caved and replaced my old fluid turbo with a Neo 2T a couple of weeks back. First impressions are very good. ERG is good for my trainer road workouts and keeps things honest. I had a bad habit of going over on intervals and sometimes straying out of the intended zone, so this is good for discipline. Sim mode is definitely more interesting on long rides too.
I do have an issue that I’d like to try to understand though. I did a Fulgaz ride a couple of days ago (Stelvio) which I did in sim mode. Tapping away at tempo (bang in the middle of z3) and keeping the cadence realistic for a long climb (85rpm) it took 90 minutes. This wouldn’t have felt particularly taxing on the old turbo and according to HR it was similar on the Neo. However, RPE felt a bit higher and the day after I was left with some DOMS in the glutes and lower back.
Now, I’ve climbed many mountains IRL and at much higher power with none of the soreness I’m being left with after that. So, I’m trying to work out what’s happening differently to affect the muscles in this way and is it a good or bad thing? The Neo feels like it’s forcing me to use muscles differently.
