Aero wheels for a small light rider

Hi guys

Am new to this forum and am hoping you guys can guide me in the right direction!

I’m after a set of new wheels. However, I don’t really know what I’m looking for. I currently have the Mavic Cosmic Elite’s which came with my bike when I bought it. This weekend just gone, I hired a set of Enve 6.7 clinchers and used them on the Ironman Wales bike course. I’ve only done that course once before, this time last year, but I can see from my times I was noticeably faster. That might be due to having an extra year of cycling in me though, I’m not sure. However, the wheels certainly felt faster on the flats. I’m on the small side (5 foot 1, 7 and a half stone) so hills have never been an issue for me. However, I’m generally pretty rubbish on the flats and these aero wheels seemed to make it feel a lot easier.

So, now I think I’m after some aero wheels 🙂 However I literally have no idea what I’m looking for! I didn’t intend on getting the Enve wheels – that was a mistake with the shop. I had asked for some FFWD FR6s but they gave me the Enve ones instead because someone already had the FR6s.

I don’t want to spend any more than £1k on a set but I really don’t know where to start. Is my size and weight an issue? I’ve never used aero wheels before and they definitely did feel a bit twitchy when they caught the wind.

Any help or advice would be massively appreciated. Thanks 🙂
