cheers

Cost me less than £30 IIRC for the last pair.

Have built two 406 wheels with SP dynamos - spokes from SJS in both cases.

A few laps of Betteshanger Country Park? Charles Henry managed 53 in 3 hours last summer

'Best' is what works for you, hence the suggestions to go and try some (or state your location: someone might be willing to let you try theirs). IME a mesh seat is easier to adjust than a hardshell to reduce pressure on painful spots / match you lumbar curve. I find a suspended 20" wheel (ICE '...

Similar wheel sizes / tyre section ?

Quite!

Our bodies bounce badly by comparison and that is the source of Heine’s suspension losses. But how does he measure these internal losses? IIRC he inferred them by coasting downhill over rumble strips and observing the speed change vs riding on the smoother surface alongside. US-style rumble strips ...

Given that the losses are in the tyres, it has to be a pretty special suspension that reduces tyre losses on relatively high frequency surface roughness eg with cyclic repetition within the tyre footprint length Which losses are you referring to here? The major energy losses in riding a bicycle on ...

Oooh, nice link. Worth looking at the onward FB link for the pix. (I'd never heard of Mitas tyres either!)

Indeed: especially the guy I saw a while back with 2 StVZO Lidl lights clamped on his bike's front fork legs (ie rotated through 90 degrees)
