Weight saving on rims and tyres is good. When spinning it accounts for more than the actual weight saving due to rotating mass / centrifugal force being lighter. Saving 250g in rims / tyres is actually equivalent of saving something like 1000g for the energy you need to move forwards when up to a certain speed, about 20 to 30mph I think.

Yep I will be taking 300g off my current wheelset, for a quarter of the price I was considering paying in the summer.
Only thing is, this could lead me to spending the money upgrading to 11spd, still not sure if it's worth the expense. |

I found that upgrading 105 to 11speed was well worth the expense. usually plenty of new or nearly new 11speed stuff on bike radar, which won't break the bank. interestingly its been reported that Shimano stuff will be reduce by up to 40% in the USA. Isn't going to happen here, but maybe it might be cheap enough to buy from there? I doubt it, as you'll get stung for duty/vat plus PO handling fees. But if you take a holiday?

Hmm good to know I wouldn't need to replace the chainset, assuming the front derailleur would be fine as well? Maybe worth changing the cassette and rear derailleur, oh and shifter. Would need to be SRAM though or it would look weird ![]() |

The shifters have different cable pull ratio's, so old 10 speed mechs won't work with 11 speed shifters.

Interesting article on power meters versus hr meters on roadcc the other day.
for the most benefit you need to use one in conjunction with the other.

OK ta will take a look.
I've been doing some of the Global Cycling Network videos on youtube, which I am hoping should be reasonably structured. That one I did earlier I still have jelly legs from.. ![]()
