The BORG31 wheelset is a semi aero, very stiff wheelset based on a wide rim which is perfect for all weather training use, road racing or CX use. The rim is 31mm deep, 24mm wide with a 19mm internal width. The rear rim is offset (asymmetric) which increases non drive spoke tension. This is useful way of increasing spoke life. These wheels are very stiff but are comfortable. They will provide secure handling and you will enjoy them. They also offer a aero benefit comparable to some deeper carbon rims.

The Cycle Clinic recommends you pick one of the IRC tubeless tyres which we will fit for you and provide all the guidance and support you need to start using tubeless tyres. These tyres can give stellar mileages, they are that good and yet provide the secure handling and comfort you want.
The wheels are properly tubeless compatible. Tubeless tyres inflate with a floor pump (IRC tyres do) and remain securely seated with no air present.
This is a all weather aero wheelset for training and racing. Tubeless tyre compatibility is perfect for all conditions. If you want to know more about tubeless tyres just ask. Personally I don't ride with inner tubes any more. IRC Tubeless tyres are that good.
There are three options
- 20F/24R with Miche Primato hubs weight limit 100kg
- 24F/28R with Miche Primato hubs - for heavy riders weight limit 120kg
- 18F/24R with Shimano Dura Ace 9000 hubs
The spokes used for options are black Sapim Cx-ray for the front wheel 2.0mm(0.9/2.2)mm/2.0mm and Sapim Cx-Force spokes 2.2mm/(1.3mm/2.2mm/2.0mm) with black alloy SILS (self locking) nipples. The Cx-force spokes have a thicker elbow than most spokes (triple butted) this means longer spoke life. Combined with the offset drilled rear rim, the weight limit for these wheels is ~100kg (this is not strict however and is likely to be conservative).
The hubs used are Miche Primato or Shimano Dura Ace 9000.
The Miche hubs have steel axles and big bearings so they are very reliable hubs. Freehubs are easily swapped between Campagnolo and Shimano. Freehub bodies are cheap and available from The Cycle Clinic (if fact all hub spares are). Freehubs are 9/10/11 speed compatible (shimano freehubs will take a 8 speed cassette). Dont be fooled by the price of the Miche hubs there are few hubs on the market that are more reliable. Rear hub bearings typically last 8000 to 10000 miles of mixed weather U.K use. Then change them for more miles of happy riding. All spares are available through The Cycle Clinic and I mean all spares down to the ratchet ring.
Shimano Dura Ace 9000 hubs. Do I have to explain why. If you service these regularly ( change bearings every 5000km) the hub will do any number of miles you care to imagine.
Kool Stop Salmon brake pads are recommend for these wheels (and all rim brake wheels) to maximise brake track life. Available for Shimano or Campagnolo holders.
Front OLD is 100mm and rear OLD is 130mm.
Simply a reliable wheelset for all weathers and combined with IRC tubeless tyres in four versions it maybe the only wheelset you need.
If you want tubeless tyres then just buy and I will fit them for you with Effetto Mariposa sealant.
IRC tubeless tyre options
Roadlite - 23mm or 25mm a good allrounder (a bit like the Schwable Pro Ones but far more cut resistant) -
Formula Pro RBCC 25mm or 28mm - the grippy durable option -
Formula Pro x guard 25 or 28mm same as the RBCC but with a extra puncture protection belt for winter use.
Formula Pro Light 25mm a light weight racing tyre
IRC clincher tyre option
IRC Aspite Pro dry 24mm
IRC Aspite Pro dry 26mm
IRC Roadlite X Guard 25mm
These tyres maybe expensive but I go to the trouble of importing them for a good reason.
