£1500 to spend - what on?

Sorry - seem to have a 7755matt stutter there  

Here's the decision - 

Today - new cycle shoes (last year's were too small), neoprene overshoes, gloves and merino socks (after numb feet on today's long ride), turbo riser block, turbo tyre, warm cycle tights

Next - new wheels and tyres, LBS recommendation. I have no idea about this sort of thing, but trust their judgement as I've been shopping there for years.

Save the rest - no TT bike at least until I have done Outlaw in case I never want to ride a bike again 

sounds like good spending so far and a good decision brit

Brit, remember that even your favourite LBS will have ties to specific suppliers. If you are seeking wheels, then they will only promote the ones they deal in. There are hundreds out there, but popularity is a very good indicator. From what I've been oggling, this has reduced to a shortlist of 3 (road wheels).

Mavic ksyrium elite
Planet x
Campagnolo Khamsin

 You may even decide that you could sell the hubby (my mis-reading) and get some carbon deep rims for race day.

Brit, I was sent this link from a fellow Pirate. I am in a similar boat of looking for wheel upgrades and not knowing my arse from my elbow

I'm also considering these though

if you are after general wheels the planet-xs look pretty good.
Aluminium braking surface - so you can use them properly unlike those crappy carbon ones.  I remember steveHo trying to brake ahead of a big corner in the rain in Regensburg on the course familiarisation ride.....with some borrowed carbon tubulars.  He needed to wash his cycle kit afterwards
50 depth - nice all round size - has some effect but not too bad in x-winds.
500 the pair - a bargain compared to heds, (1000 the pair) or zipps (2000) or sram s40s, (900 pair)

personally I dont like the prfile ones.... no idea why - just bike tartness I think

Currently £4001 I got the 60mms last year. Very happy with them.

What do you mean, 'use them properly'?

Aluminium rim braking surfaces work.
Carbon brake surfaces are light, and er, don't work ? Or they need special pads probably.

It may be something to do with time triallers wanting to hammer out the highest speed for the longest possible time, and that means not braking for corners or downhills. You don't see carbon disk brakes on downhill mountain bikes.
