Back in 2012, Syntace rolled out collection of wheels spaced 5mm apart in width and ranging from 25mm to 40mm wide. Hit that link for rim and wheel weights for the MX range.
Now, those wheels have grown to include a lower level “M” series that share the same rims but get less expensive hubs. The MX series remains the high end and switches from bladed Sapim spokes to triple butted Sapim spokes. Weight is about the same, but they say that should make for easier maintenance and replacement availability. The W40MX remains a 26″-only offering, and the W35MX is available in all three sizes. They use the German-made hubs with 36 points of engagement using a “spur” system that’s eerily similar to DT Swiss’ toothed rings.
The MX hub is shown above. The “M” hubs use a heavier shell and only have 18 points (20º) of engagement depending on model, and those wheels will use silver spokes instead of black. They’re still triple butted, but they use 28 spokes instead of the MX’s 32, so the wheels won’t be quite as stiff. Retail for the wheels are $1,299 for MX and $989 for M.
This is what a 40mm wide rim looks like: BIG!
