With the DC12 X12 skewer Tune brings their lightweight elegant skewer design to the stiff thru axle X12 standard. The 12x142mm rear axle is a leap forward for rear suspension stiffness and with Shimano putting their efforts behind it we're sure it's going to be widely accepted. To us there's very obvious reasons Shimano has worked with this standard. By combining the skewer and axle into one solid piece with the wider 142mm spacing the drivetrain, hub, disc brake, and frame act more as one solid piece. Increasing stiffness during sprints and decreasing any chatter while braking. This keeps the rear wheel on the ground decreasing braking distance and keeping a smooth confidence inspiring line into any corner.
Most frames are compatible with the Shimano Standard of the DC-12 X12 skewer. Most frames that do require an adapter will already have it. Shimano has chosen to ship their XTR M988 Thru-Axle skewer with the u.a. adapter for BMC and European brands such as Merida.
If you need a Syntace X-12 Standard skewer you can order that directly or get the adaptor to adapt an existing Shimano DC12 X12 skewer. To install or remove an adaptor simply pry the adaptor open using a small flat head screw driver and slide it off the skewer.
