BORG26 2:1 wheelset - rim brake front and rear


The BORG26 wheelset uses an alloy rim that tubeless ready (tape, valves and tubeless tyre lever supplied) 26mm deep and 24mm wide. Its a stiff rim. The wheelset has 20 spokes for the front wheel and 24 for the rear.


  • 26mm deep 24mm wide tubeless ready wheelset
  • 700c
  • 2:1 lacing for the rear hub
  • Sapim aero spokes
  • Shimano 8/9/10/11 speed, Campagnolo 9/10/11/12 speed or SRAM XDR 12 speed compatible.
  • Reliable NTN bearings
  • Weight 1610g for a pair (1625g with tape)


The rear rim has a 3mm offset to improve tension balance which is further improved by the 2:1 lacing. All the tricks are used to make this a reliable but fast and fun wheelset to ride on. The rear wheel lacing pattern makes this wheel particularly stiff with a reduced tendency to rub brakes compared with other wheels using rim of a similar depth. It also makes it quite responsive.

The hub is a BORG Wheels creation. The front hub has 2x 61901 NTN bearings running on a 12mm alloy axle. 

The front wheel is laced radially with Sapim CX rays (black) and black alloy nipples. Sapim HM nipple washers and nipple freeze are used to ensure rim and nipple longevity. 

The rear 24H wheel is laced 3x drive side and radial non drive side in a 16:8 pattern. Sapim CX force triple butted aero spokes are used along with Sapim black alloy nipples with Sapim HM nipples washer and nipple freeze to ensure the longevity of the wheel. 

2:1 lacing offers the rider less brake rub, stiffer rear wheel due to the optimised geometry and longer spoke life. Pads are still recommended to be 1.5m. to 2mm from the rim for maximum mechanical leverage.

Shimano 8/9/10/11 speed, SRAM XDR 12 speed Campagnolo 9/10/11/12 speed freehubs available. The hubs use NTN 6901 bearing for the front wheel and NTN 6902 bearing in the rear hub shell. The freehub has NTN 6802 bearings. 

The hub uses a large 36T ratchet ring. The freehub has 4 independently sprung pawls. Its loud. I like that and it's also a sign of strong pawl springs, lots of pawls and teeth, this a is a good thing.

The NTN bearings are offered with contacting (red) or non contacting (black) seals. The contacting seals offer better weather sealing but  higher drag than the non contacting seals. When riding though it's impossible to tell which bearings you have. Contacting seals loose much of there contact with the bearing above 5 mph. Non contacting seals loose contact and hense let more water and grit in. So expect significantly longer bearing life from the bearings with contacting seals. The non contacting seal bearing are fine though and the type of seal commonly found from other cycle bearings. NTN is a top tier bearing manufacturer and there bearings are made to tight tolerances so expect the non contacting bearings to last longer than others anyway. I use the contacting seals in my personal set. 

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.

Wheelset weight is 1610g but dont be fooled into thinking this will make it feel heavy. There more than one way for a wheel to feel light. Making it responsive to torque inputs is one way and the other is to make it so the wheel deflects little under high loads.
