That was indeed me.
That was the gillet I got from Charlotte OTP earlier in the week.
It's inaugural outing.
Because I'd messed up the cassette, I lost the middle gears which forced me into either too low or too high a gear most of the day!
I was also cheating a wee bit as I was the only person with aerobars that I noticed.
I find that being on the areo extensions suits pushing a slightly higher gear anyway.
Glad you enjoyed your day out.
