Upgrade wheels and pedals??

Wiggle got no C24's in stock. Evans also have em for £640 but they might do a price match.

You can get some Dura Ace C24's for about £600 at the mo. Bit extra but save on pedals, maybe just go for some Shimano standard road SPD's for £40 ish and get them, wheels will give you more upgrade than pedals in my opinion.

I bought some Shimano Ultegra wheels - solid, stiff, quite light - love 'em.
My Dad has some Fulcrum Racing 3's - also very good.

RS11's aren't bad. Perhaps ride them for a while before splashing out on new wheels? At the moment my cycling budget goes on things that make my body fitter/faster, rather than my bike.

The first thing I'd consider is decent tyres - they make a world of difference in terms of bike handling & confidence, and can drop a nice chunk of rotating weight too.

I like Speedplay (and don't seem to have the high-maintenance thing that others report), but then I have old knee issues which the speedplays are good at accommodating. I had a chat with Jon-Allan Butterworth (paralympic sprinter who is involved with a new LBS near me) and he said that Speedplays worked for him when he was coming back from a knee injury, but as a sprinter he prefers minimal float to really 'lock in' his position - think he mentioned Look blue cleats.

I bought some Campag Shamals in sale from Wiggle reduced from a grand to 600 ish. They are superb. Very light 1450, ceramic bearings, very smooth with mid section aluminium rims. They do come in either campag or shimano compatible hubs. Recently reviewed in this months cycle sport mag. really like them

Pedal wise... there is nothing better function wise than the old Time RXS pedals. Great modulation of float, cleats that tune to your bio-mechanical needs, cleat/pedal body interface that doesn't degrade over time.

Only problems are that the bearings can die on you, and the cleats have a habit of breaking if you stamp your foot or something.

As for Wheels... I've had the RS81 35mm wheels on the bike for training/chipper racing, and I have been suitably impressed. They are not the lightest by a stretch, and by the noise they make, I question their aerodynamic qualities, however they are reliable to date, and the rear transfers power to the road commendably.

My missus got her 2014 fulcrum 3 for just over £300 from an online retailer in France

Got my 2014 fulcrum 5 price matched by Evans for £170

Very impressed by both wheel sets, especially the sheer value

You can get Fulcrum Racing 3's for a smidge over £300 at the minute if you shop around. That is a spectacular price and serious bang-for-buck for a superb set of all round wheels. If I were in your shoes that'd be what I'd be looking at.

As for pedals: They're like saddles. No-one can agree on which are the best. The usual derision dictates that Shimano break, Time cleats wear out, Look squeak and Speedplay are too high maintenance. It's all rubbish of course but you're unlikely to get a concensus.

I personally like Time road pedals.

Why not ride the same type of pedals as your MTB?

I ride speedplay .. they nice, but boy are the "high maintenance" !!
Going to go back to Looks myself. Perhaps you might consider Shimano DA
pedals ?

Great choice of bike. Either the 105 or Ultegra model will be a blast to ride with any set of wheels.

Your choice of wheels needs to take into account your terrain and road conditions, weather, body weight, riding style. Some of the wheels you mentioned are very different. Some are also not that much better than the stock wheels.

If you can get either of the RS81 wheelsets for £500 ish that sounds like a great deal.
