I do TT’s with a front Tri-Spoke and up until now, I have only had an 80mm deep section rear wheel.
I have found that I tend to get buffeted about in moderate winds and also when some traffic passes, when doing TT’s. Nothing too severe, but severe enough to be a bit troublesome.
A few days ago I borrowed a rear disc wheel and did a TT. I seemed to go about 30 seconds faster on the 40k TT than my average times, but the biggest thing I noticed was less buffeting around at the front. (It was still quite a breezy day 10mph to 12mph winds).
Am I imagining this improved stability or has anyone else noticed this?
What are your thoughts because I can’t explain it to myself why there may be an overall stability improvement with a rear disc wheel and my trispoke front.
