BORG31W DISC wheelset 650B or 700c for Gravel


What we have here is a robust gravel orientated wheelset for wider Gravel/road tyres.

The rims are 30mm wide and 31mm deep. The internal width is 25mm. This means the partical minimum tyre width is 36mm. Max tyre width is around 65mm. You could use these wheels for XC racing. Maybe you should.

The rim is tubeless compatible meeting ETRTO standards. Therefore the wheels are supplied tubeless ready.


  • 30mm wide tubeless ready gravel/XC wheelset
  • 30mm deep
  • 28 spoke front and rear
  • Shimano 8/9/10/11/12 speed, Campagnolo 9/10/11/12 speed, SRAM XDR 12 speed, Campagnolo EKAR 13 speed and Shimano Microspline 12 speed freehub bodies.
  • 142x12mm/100x12mm, 100/135mm QR or 12mm TA for cannondales with 6mm offset (AI) axle standard options. Please state at check out

The hubs used are BORG Wheels Disc with centrelock rotor mounts (pictures show different and show the older Miche made BORG DX hubs)

  Freehub bodies for

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

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. 

The spoke and nipples are the last trick. Black Sapim Force triple butted 2.0/1.8/2.2mm (at the elbow where it matters) give long service life. The elbow being 2.2mm in diameter has 21% more cross-sectional area than a Sapim race or DT Swiss Competition spokes.  What is not to like about that? The nipples used are silver Sapim brass nipples. 

So, in short, this wheelset uses all the tricks I know to create a stiff reasonably light but robust wheelset that will give you smiles for miles.

Weight is an anti weenie 1840g. 

These wheels will take you on adventures and back to normality again time and time again.
