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.

at least the wheels will support the 11sp cassette . I'm interested in the psychological aero effect and also the increase in avg speed due to red coloured rims. My bike will have more bling than lewis hamilton's goldie chain
UPS have the wheels , shame the weekend is a bit moist

Just replace the groupset once its worn out. You dont need to change the chainset (unless thats worn out) it will work fine with 11speed.

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?

Ah I was in Florida last year but wont be happening again for a while.

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

Don't know about SRAM, but with Shimano you change the shifters,chain,cassette, front and rear mechs.

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

Power Meter is fitted, Just done a 30 minute interval session on the turbo. Was interesting just watching the numbers...

Need to understand a bit more what its telling me I think...

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..

Thats power workouts for you
