Road bike (wheelset enquiry)

I had a set of Quattro wheels and they were excellent, would recommend.

From your list, I'd go with the Racing 5 LG. I rode a pair all around the mountains just inland of Valencia for a few months last year and they were faultless. I put them on the Mrs' road bike after I bought a pair of Boras and they are still going strong.

But really, I would look at a pair of Zondas. I've had them on my commuter for over 20,000km of all-weather London commutes over the last four years and have regreased the bearings twice.  They're ace.

have you considered powertap as a training wheel?

I can recommend the Shimano Ultegra wheelset. They're strong, have bladed spokes and are tubeless ready.

although a bit outdated design

DT SWISS R 24 SPLINE and Fulcrum Racing 5 LG are both nice wheels, not too heavy, wider internal rim width, both about the same price. Some nice tyres to go with them would be good too continental 4000s 23 or 25mm 25 mm if they will fit in your frame. Best of luck. 

What is your weight

What is the type of riding you are doing

Are the roads flat/smooth tarmac or broken/undulating?
