The BORG22 disc brake wheelset is designed/built for high miles and riders over 100kg. Based around a rim from Kinlin and BORG DX hubs. These wheels are more than suitable for CX/gravel use too. The is a dynamo option with the SON 28 hub.
This is the touring/heavy rider version with a 120kg weight limit.
Let me know which axle standard combination you need at checkout.
The wheels can be built for the Cannondale 6mm offset rear used in one of there CX bikes.
- Centrelock BORG DX hubs
- Wide tubeless ready rims.
- 32 spoke count.
- Thru axle and Q/R compatibiliaty
- Campagnolo, Shimano or SRAM XD driver compatibatility
- triple butted black spokes and brass nipples.
- 10,000mile/16,000km warranty against spoke failure and other fatigue failure's.
- Centrelock disc brake mounts.6 bolt adapter available here.
- Centrelock rotor lockring available here.
The hubs used are BORG DX with centrelock rotor mounts (new pictures are needed). 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 is supplied with a Shimano external spline lockring. 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.
It is advisable if using Shimano made cassettes to tighten the lockrings up really right. RTF is what I call it. 40 to 50 Nm is required. For a Miche cassette for Shimano 40Nm is sufficient as these notch less easily. If you don't own a good torque wrench get a mechanic to fit the cassette for you. The freehubs are expensive, no need to ruin prematurely.
The rim is 435g in weight and is 19mm wide internally 24mm external width. It is 22mm deep and is tubeless ready (tubeless rim tape is installed on every wheelset). Normal clinchers can be run of course. The rim is an offset for the front and rear design which means improved spoke tension balance. This one trick to extend spoke life.
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. I deploy all the tricks as tubeless tyres compress tubeless compatible rims (tight fitting standard clinchers do too) and this cause a significant tension drop that must be accounted for when building the wheel. I cannot raise the tension as some tyres cause a bigger drop than others. So tricks to improve tension balance and extend spoke life are a better way of creating a reliable wheel for all riders regardless of the tyres they choose to fit.
What you get
- 32F/32R wheelset with black triple butted spokes and brass nipples
- Q/R or 142x12mm/100x12/15mm in any combination
- Silver brass tubeless valves and tubeless tape is supplied.
- IRC tubeless tyre levers
- 5 year or 10,000 miles guarantee against spoke failure (anything reasonable covered too). The rims won't wear out so I can't do a guarantee for the life of the rim that might be a very long time.
