BORG31 All-Weather Aero Wheelset


Customer Reviews

Based on 5 reviews Write a review

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.


  • A robust all weather race orientated wheelset.
  • Big cartridge bearing hubs
  • 31mm deep.
  • 24mm wide tubeless tyre ready rims (tubed tyre compatible too).
  • Stiff yet comfortable.
  • Triple butted Sapim aero spokes.
  • Shimano8/9/10/11 speed, SRAM AXS 12 speed or Campagnolo 9/10/11/12 speed freehub.

  • Life if the rim warranty.
  • Weight from 1655g

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 is one option

  1. 20F/24R with Miche Primato hubs

There is no weight limit. Rider up to around 100kg should see no reliablility problems. This covers most riders. Heavier riders are advised to pick the BORG26 which is built in higher spoke count. I do not build this wheelset in higher spoke count.  

The wheels can be built with Shimano Dura Ace hubs but again the rim finsh is gloss black not matte and therefore can't be part of this listing. 

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.

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 8/9/10/11 speed compatible for Shimano, SRAM AXS 12 speed and 9/10/11/12 speed compatible for Campagnolo. Don't 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. 

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.

The Cycle Clinic is a stockist/importer of IRC tubeless and clincher (tubed) tyres. You can opt for any IRC tyres to be fitted to your wheels. Other brands are stocked too,  and if you buy tyres from this shop I will fit them and set them up with Maxalami Sealant. Please note if you buy tubed tyres buy tubes also.
