Over-inflation ?
Or under-inflation...
Dunno. I still reckon people are running on inappropriate, light-and-fragile minimalist kit in order to go as fast as possible.
After all, a sportive's a race innit ?
I did the Cheshire Cat on my Winter bike because I'd only been out on the Summer bike twice previously this year due to weather and as the positions on the two bikes are slightly different I knew I'd end-up suffering a lot if I did 120m (inc to/from the start) on the bike I hadn't got my body used to.
I race-prepped it (well, I took off the rack and lights
) but it probably still weighs 5 or 6 lb more than the Summer bike.
- on the other hand, I'm not at Summer fitness either...
There seemed to be two distinct groups out, those running winterised bikes with full guards or raceblades, those running the latest bling carbonfibre.
