Please note new rims have arrived meaning the wheels are lighter than previous reviews indicate. 

The BORG45 Disc wheelset is reliable aerodynamic wheelset which will allow you to ride a bit quicker for the same effort. Drag reduction comes from the depth of the rim but also the width keeping the tyre width around the width of the rim. 

In addition the profile of the rims and the rim tyre interface results in stable handling in windy condtions. Well as stable as you would be on shallow rimmed wheels. 

The rims are  26mm wide (19mm internal width) 45mm deep disc brake specific wheelset for real tyre widths of a minimum of 25mm. IRC Formula Pro RBCC  or X-Guard 25mm are suggested as these sit at 25mm on these rims. The 28mm tyres are again 28mm wide.  So tyres that sit 25mm to 28mm wide are aerodymanically optimal for this rim.  Max suggested max tyre width is in the region of 40mm width.

Wider rims are not currently offered as these are meant for wider tyres. For example a rims that are 21mm internal width are meant for 32mm tyres or wider (ideally wider). Narrower is aerodynamically faster no matter how you try and contort physics. 

These are light, stiff, aerodynamic wheels that got a best value award in Cycling Weekly. The wheels are hand built in Suffolk, U.K. These wheels are built with specially selected parts for high miles and to help you ride faster too. 

The wheels can be built for the Cannondale  6mm offset. 

They are very stiff and therefore feel responsive and spoke life will be very long. 

The rims have the ideal profile for making them very stable in cross winds, and your tyres will have an optimal shape.

Please state at checkout if 100*12/142*12mm for Cannondale (Ai) 6mm offset bikes is required.

The wheels will stand up to road, CX or gravel use. 

Spoke count is 24 front and rear. 

Pillar Wing 20 spokes in black are used with black alloy nipples  hubs. Silver spokes and silver nipples can be used with the Carbon Ti coloured hubs.  Pillar Wing 20 spokes are actually a wee bit more aero and a stiffer than the Sapim CX rays we used to use. Same weight though. it is also a triple butted spoke which improve spoke life at the hub flange. 

There are two hubsets available. 

1) BORG Wheels with centrelock rotor mounts:

Freehub bodies for

  • Shimano 8/9/10/11speed
  • XDR 12 speed  driver
  • Campagnolo 9/10/11/12 speed freehub
  • Campagnolo N3W 13 speed freehub
  • Shimano Microspline

are available and are interchangeable.

The freehub has 4 independently spring loaded pawls and a 36T ratchet ring. It is advisable to re-grease the freehub mechanism with good grease like Rock n Roll Super Web to keep the hub quiet and to stop water ingress weakening the spring. 

They are a large flange design because large flange hub reduces the braking loads on the spokes compared to small flange designs.  The front hub has 2x NTN 6902 LLB bearings and the rear hub has 2x NTN 6902 LLB. The freehub body has 1x NTN 6902 LLB and 1x NTN 6802 LLB for shimano and  1x 2x 6803 bearing for Campagnolo, XDR and N3W freehubs . All spares are available. 

2) Carbon Ti disc brake hubs for centrelock rotors. Available in a choice of colours. Black, red, blue, green, gold or silver. Black hubs will be assumed unless you tell me otherwise. The hubs are available 4 pawl freehubs. Shimano 8/9/10/11/12 speed, Campagnolo 9/10/11 speed or SRAM XD 11/12 speed.

The hubs are  100x12mm 142x12mm TA frames only. No conversion kits are available. Carbon Ti thru axles are available as well. Let me know which axle standard you need and I will convert.

Simply high end wheels without the high-end price tag (nearly).

If you buy any tyre (with tubes if applicable) I will fit them for you to your wheels.

The wheels are supplied tubeless ready too with tape, valves and IRC tyre levers. tubed tyres can be used as well. 

You see why I have not put tyres into the listing. If tyres are bought I will fit them although you will need to buy the tubes with clinchers.

Warranty notes:

If the rim cracks (spoke holes) then that is a warranty (none have yet)

If a spoke breaks without external damage as a cause or the wheel goes out of true then that is a warranty.

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