Re: Cycle route 2: prevailing winds

If in late spring / early summer then sea breezes would be expected along the coast. These usually start around mid-morning, and veer (eg go from southerly to westerly) during the day. If the gradient wind is a mild north-westerly on a south facing coast then expect a big sea breeze (eg 25 mph) late...

Re: MTB Cleats Advice needed

I am new to the world of MTB and SPD shoes and despite my research I still am not confident on how to proceed. Er, I thought the trend in off-road MTB riding was for grippy soled shoes and pedals with pins (eg Nukeproof ). Using pinned pedals with lightweight boots has certainly improved my MTB exp...

BMX riders don't seem to like reflective strips either eg Maxxis

Re: Challenge suspension explain?

I've never ridden (or seen) one, but that suspension shock seems in precisely the wrong orientation: will every pedal stroke not contribute to compressing the shock? Could it make for a bouncy rear on steep climbs? The shock on my Fuego is pretty much perpendicular to the chain run. Suspension elem...

Re: Cycling for Disabled People.

'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 '...

Re: Suspension power losses/savings

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 ...

Re: Suspension power losses/savings

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 ...
