Neaves Road TT testing


Out to Neaves Road to do TT testing and practice drills. 4x5km with the P2C / Bontrager Aeolus 5.0 wheelset. The 1x10km with the P2C / Bontrager Aelous 6.5 Wheelset.

The weather was almost perfect for iBike testing except for a 5-10km wind from the North. I haven't downloaded the iBike yet, so don't know how successful it was. I was hoping to get some solid numbers for Cda and CRR. I'll do another post once I've had a chance to look at the iBike data.

I think I did do a PB on the last drill with the Aeolus 6.5 wheelset. About 14:10 for 10.1km, but that was with two turns. Normally I do this course from the south end and do one turn at the North. I was running out of time today. So after doing the coast downs and "4 mile ride" I only had just enough time to do the course, but from where I was parked, in the middle. And because the turns where un-supervised I have to take them fairly slow to make sure there are no cars. So this would have been about 13:40-13:50 if done in the normal manner.

Also this was the last drill for the day, not much left in the legs, Pavg was low, only 295 watts. So presumably getting reasonable aero and rolling resistance numbers.
