100/135mm QR


100*12/142*12mm for Cannondale offset bikes.

This is a disc brake specific wheelset that is black in colour, tubeless ready and ready for the road or trails. The 32 spoke set is suitable for heavier riders, loaded riding or E-bikes. The spoke, nipple,rim and hub choice all make these wheel E-bike ready. The hubs are rated to 330Nm of torque, the large flanges minise spoke tension changes and the triple butted spokes along with the brass nipples and washers ensure the whole wheel is reliable.

Use it road or for MTB XC use or gravel as it now called or as a touring bike or audax rides. The extra width means a comfortable ride. 

Minimum tyre width is 36mm but tyres 40mm to 60mm are ideal. 

650B rims do make quite a bit of sense. For touring bikes, they allow fatter tyres, the same is true for gravel bikes. With a 40mm tyre the rolling diameter is the same as a 700c wheel with a narrow tyre. The bigger tyre volume means more grip and comfort over rougher ground. Bigger tyres are faster off road. Also, those who load up the bike 650B wheels are stiffer and have a higher load capacity than there 700c cousins.

To me, there is no difference between a 650B wheelset aimed at gravel, MTB or touring. If it works for MTB it will work well for the other two. 

The 700c/29er wheelset is still robust and will carry the load. It is light enough to be responsive and stiff enough to take whatever the road or trails throw at you.

The hubs used are BORG DX with centrelock rotor mounts. Q/R, 100x12/15mm and 142x12mm compatible in any combination. Just tell me at checkout what you need.

6 bolt adapters made by Miche are available. The rear hub requires the use of an external spline lock ring.  Freehub bodies for Shimano 8/9/10/11 speed MTB or road, Campagnolo 9/10/11/12 speed, and SRAM XD driver are available and are interchangeable with nothing more than possible bearing preload adjustment.

The freehub has a titanium core/pawl seat springs with an aluminium alloy main body. The freehub has 3 spring loaded pawls and a 30T ratchet ring. It is advisable to re-grease the freehub mechanism with good grease like Rock n Roll Super Slick or Super Web to keep the hub quiet and to stop water ingress weakening the spring. 

Why BORG DX hubs? Well, I have had Miche make these in 24H, 28H, and 32H drillings. They are a large flange design because large flange hub reduces the braking loads on the spokes compared to small flange designs. The bearings are not the normal ISO grade 0 or ABEC-5 (enduro) that you find in many hubs even high-end ones. SKF supply the bearings for the BORG DX hub but these bearings have much tighter tolerances on the outer and inner diameters, the balls are to a much higher standard, even the grease is a special formulation. All this is designed to increase bearing longevity particular in wet weather operation. To get the longest life, pressure washing the hubs should be avoided and the cassette should be cleaned removed from the hub. The front hub has 2x 6803 bearings and the rear hub has 1x 6803 non-drive side and 2x 6803 drive side. The freehub body has 2x 6803 bearing. The same high-grade bearings are used throughout the hub. All spares down to the ratchet ring are available. Simply I have had these hubs made without compromise.

Because these wheels would appeal to audax riders a dynamo front hub option is offered with a the SON28 centrelock for Q/R or tru axle. I do not build with the Shutter precision hubs anymore due to recurring warranty issues. 

Spokes will be black Sapim Force with brass nipples for 32 spoke wheels and for 28 spoke wheels Sapim black alloy nipples are used. There is a 120kg weight limit on the 32 spoke wheels. Spoke nipples washers are used to ensure the rim won't crack.

      For outside E.U customers the following applies. The order value is with VAT. VAT is 20% so order total for the parts/6 = VAT amount. 

      Then add the UPS shipping amount. The true amount may differ. the VAT is used if you have under paid if more is due then we will let you know. If you have over paid I will work out what and refund you.
