The BORG50C wheelset is an aerodynamic, stiff, responsive race ready wheelset. The wheels are handbuilt in Suffolk, U.K and they are built to last and make you quicker. 

The rims are 50mm deep and 26mm wide. The internal width is 19mm. The industries best aero spoke is used along with hubs made in Italy.

The wheels are comfortable and the aero gain just helps you feel like you're on a good day which is always welcome. The wide rim helps improve the bikes ability to corner as the tyres don't deform as much under side loads and the braking is great in all conditions. Crosswind stability is also very good. 

Recommended tyre size is an inflated width of 25mm for optimal aerodynamic performance. 27mm and 28mm tyres though are not going to harm performance much at all. It's tyres bigger than 28mm that start to catch the wind more and offer an aerodynamic penalty. 

The BORG50C rims have a gloss black logo which is part of the rim and is slightly recessed. Once you see and feel it you wonder why the BORG50C is the only wheel to have such logo's.

IRC tubeless tyres are easy to mount and remove. Max pressure for the rim is 120 psi but no more than 100psi is necessary depending on tyre choice and rider weight.

The rims have a good brake track with a high Tg resins. The resins used means rim overheating is not an issue but we can't change Physics, carbon rims dissipate heat more slowly than metal rims. Rule of thumb if the braking load would get alloy rims to hot to handle then don't do that decent on any carbon clincher rim. The wheels are supplied with Campagnolo carbon brakes pads, in Shimano or Campagnolo fitting. Braking performance is as good as it is on alloy rims with good pads and brakes. Braking in the wet is good too. Rim wear does not seem to be a big issue on these rims either. Use of the supplied pad is required for warranty. Rim overheating is not an issue with the recommended pads but can be an issue with some pads including SwissStop.

The spokes used are Sapim CX-Ray with black SILS alloy nipples. Heavier riders can ask for Sapim CX-Sprint spokes for the rear wheel. Add a note at checkout requesting this or send an email. These stiffer spokes improve the rear wheels lateral and radial stiffness, thus extending spoke life and reducing brake rub. 

The rear 24H wheel is laced 2x and the front 20H wheel is laced in a radial pattern.

Hubs offered are Miche Primato made in italy - wheel set weight 1665g. You get big bearings that last, steel rear axle, bearing preload adjusters, Shimano 8/9/10/11 speed freehub, SRAM XDR 12 speed or Campagnolo 9/10/11/12 speed freehub. A robust all weather hubset that once you have ridden for a few thousand miles you'll understand why these are used.

All the Campagnolo freehubs offered are 9/10/11/12 speed compatible. All the Shimano freehubs offered are 8/9/10/11 speed compatible and they come with a spacer for 8/9/10 speed cassettes (although an additional 1mm spacer supplied with a 10 speed cassette is needed too).

The XDR freehub is for SRAM AXS 12 speed cassettes. 

The BORG50C wheelset are supplied as wheels tubeless ready but are tubed tyre compatible.

What you get

  • An aerodynamic wheelset front and rear.
  • Tubeless rim tape, tubeless valve and extenders
  • Miche Q/R skewers
  • Campagnolo carbon brake pads in Shimano or Campagnolo form.
  • The best guarantee (for the life of the rim against spoke failure and anything that could be termed a defect)
  • Crash replacement at cost of parts only no labour.
  • Tubeless tyres installed if bought with the wheels

Warranty notes:

Brake track warping due to overheating is not a warranty fault. I will however rebuild at cost of the rim only. You need to observe the rule of thumb in the text above and only use Campagnolo red pads to avoid overheating issues.  

If the rim cracks then that is a warranty

If a spoke breaks or the wheel goes more than 0.5mm out of true that is a warranty

If a fault with the hub appears that is is not normal wear then that is a warranty
