It’s been busy this week and one of the highlights was building two pairs of Tune King MK 20mm front hubs and Kong Ti rear hubs onto Stan’s rims.
The King MK is Tune’s freeride / downhill 20mm front hub. At 155g it’s about half the weight of most of it’s competitors. The shell and endcaps are both aluminum.
The Kong Ti hubs use an aluminum shell and axle paired with a titanium freehub body for a total weight of 238g. This is Tune’s most versatile mountain bike rear hub and can be used for anything between XC and freeride use. For full downhill bikes they make the bolt-thru axle Kong MK and for XC racers with very deep pockets there is the carbon-flanged Princess hub.
Pair #1 use the 420g ZTR Arch rims, DT Swiss Revolution spokes, and a combination of alloy and brass nipples. These are to go on a 5″ travel All Mountain bike and weight on this pair is an incredible 1532 grams! Considering the durability and that the wheels are tubeless-ready this weight is very impressive.
The quick release is a Tune AC17 which uses a titanium axle, titanium handle and titanium centering springs. The end caps are aluminum. Weight for the quick release is 29 grams.
Pair #2 use the heavier, wider ZTR Flow rims with the same spokes, hubs and nipples. These are to go on a 6″ travel freeride bike and weigh an equally impressive 1628 grams. Most wheelsets fitted to 6″ travel bikes are over 2000g and often closer to 2500g so removing this much weight from the bike will have a huge impact on it’s performance.
