I saw the post … I’m way way slower than that, and really wouldn’t fancy it in a race.
I got a puncture on a group ride three weeks ago, Bolton loop with people from all over the country, I’m pretty slow with flats, but the Easton slx alloy rim and huge gp 4000 tyres ( says 28 mm on the side, but there considerably bigger than 5000”s ) were sorted with no levers!
Even bone shaker alley, the bit past the school was fine on those bad boys.
How heavy is it? I always used a disc, because it was a Zipp 900, which is essentially the same as a deep rim in weight. But a lot of the ‘cheaper’ (relatively!) discs are pretty heavy.
Newer one is clincher honeycomb in the middle and it’s not too bad, it’s heavier than most of my rears but two of those are basically hill climb wheels.
It has a slight wobble2?mm but brakes really well, I can mend a puncture on it easily and it makes a really loud noise, obvs the most important bit.
