Mavic Aksium or Giant FIR Wheelset!
Hi everyone, this is my first post on this site so bare with me!
I bought last year a Giant scr c2 and it came with the Mavic Aksium wheels of which I must admit I haven't had any problems with, however I do have a set of Giant FIR from an old bike of which is currently on the turbo trainer. Without going through the fuss of changing everything over and giving them a test run what do you think would be the better of the two.
This is curiosity more than anything but I would hate to think that the better of the two wheelsets where static on the turbo trainer!

Here is something which might be a good food for thought, as you have Mavic Aksium.0 -
Hmm, very interesting. Although there was no mention of my old Giant FIR wheelset it does show what the difference is between a really good wheelset and mine are!
I have googled them but haven't found much info so far except they were cutting edge at the time and now have been superseeded by lighter and better designed wheelsets.
I think i'll just give them a go and see how I get on!
Thanks for that.0 -
Conclusion?
A set of $15,000 wheels require half the energy as a set of cheap-o wheels to accelerate up to speed... only one problem with that test... they forgot to add the mass of the bike + rider into the equation. So saving 75J is probably bugger all in real terms.
A nice test but it is sponsored by a company that is trying to justify the sale of ultra high end wheelsets. No suprises there.0 -
Yes I do understand your point, believe you me i'm not just about to go out out and buy a set of wheels that cost the same as a small car!!0

Well, if there is always the same rider with the sam bike who tests the wheels, I guess this is not a problem.0 -
I don't mean that.
I mean what is the amount of energy to accelerate a 'standard' 75kg human being + 8kg bike? 100J? 1000J? Whatever it is, you have to add that figure on to the figures for the wheels. And all of a sudden, saving 75J overall between light & heavy wheels doesn't seem as much... they're making out like you'll save half the energy just by swapping out wheels. Rubbish!0 -

I totally agree. But on the other hand, you must not forget that adding additional loads (rider, frame, other parts...) will highly influence the performance of the wheel. The fact is that there are minute deformations if very good wheelset is used, but if you use a cheap set than it is very likely that rims will bend which is certainly not good for their performance. Consequently a lot more energy will be necessery to accelerate.0
