Wheelset, which would you choose?

Having been faced with a similar decision recently and living in the UK too () I did some investigating on how important weight is. For my system weight of 70kg, at 250 watts up a 5% grade, an extra 100g costs you just 0.000965% in time. Pretty depressing for the WeightWeenie in me…

^This!!
This is exactly my experience (and a UK guy here too). After a lot of thought, and a play around on bikecalculator, I confirmed that everything else being equal, weight is actually much less important than you’d think. I seem to recall calculating that 500g would cost me about 42 seconds… up Mount Ventoux! It was a key factor in my ordering a custom steel frame.

More relevantly to the OP, if speed is a real factor in the decision, the Winspace 50s are likely to be the most aerodynamically efficient and therefore the fastest.

I think Cam Nicholls has talked about Winspace on his Youtube channel iirc.

EDIT: I re-ran the calculator - it’s 46 seconds
