Zip 404s are hardly much lighter at 1615g and cost nearly £1600!
Also, a few 100g is neither here nor there once you have 2 full water bottles and you're sat on the saddle (not calling you fat btw).
I suspect the light deep section is probably the AX lightness ultra 55t
http://ax-lightness.de/en/cycling/bike-components/laufraeder-rennrad-ultra/ultra-55t/ at well over £2000 and 1125 grams. That's a lot of something else for your 575 grams
Aero over weight every time.
I would rather have aero wheels weighing 1700g than those £5k lightweight climbing wheels.
Ditto.
People end up in turmoil over this not really realising that tyre choice, position on the bike and even the spares you're carrying or water bottles chosen are more likely to have significant impact than 1-200g.
Unless you're competing in Hill Climbs, factor it it but don't let it be the deciding factor.
Thanks for the help. Could I get more guidance/suggestions?
My bike is a Planet X London Road - a £1k aluminium framed commuter bike with Sram Rival and hydraulic discs (I can sense the roady sick rising in the back of your mouths!) with £100 cx wheels. It's got clearance for wide tyres and isn't very aero.
Here's a pic.
Please forgive the set-up It's left over from when I co-opted it into triathlon duties... The saddle is a bit higher and forward than usual.
I was considering upgrading the wheels to improve performance.
I am currently working on weight loss, but I do other sport besides cycling. I'm probably approx 19%ish bodyfat, give or take 3%, and about 93kgs at 187cms. I've come down from 110kgs. Realistically I'm going to struggle to lose more than a few kgs - I'm aiming for 88kgs but this will take a while.
In the meantime, I'd like as much help up hills as possible (on a budget of £300-400)
