Eccentric inserts are used to initially center the wheel within the frame. After the wheel is initially centered the eccentric insert is then removed and replaced with the concentric insert.

• concentric, 0 mm
• excentric, 0.5 mm
• excentric, 1.0 mm

Syntace X-FIX key (int. pat. pend) is the perfect addition to the Syntace X-12 through-axle system. It doesn’t matter where and when you need it, the Syntace X-FIX key is always there. Whether you are assembling or removing an X-12 rear wheel quicker than with conventional “quick” releases, fine adjusting the seat or stem angle, moving controls or adjusting the brake calliper. And what a bonus: No additional weight when compared to standard QR’s which are attached to the axle.

These non-quick release skewers require a special Allen wrench (included) to open, thus stopping most casual wheel thieves. Sold in pairs.

Due to different spacings, you may need to trim excess off the skewer.

Please note that these fit frames with 127 to 135mm rear spacing.

• Size: Front 100mm, Rear 130/135mm
• Color: Silver

Did we need to make a quick release set this nice? No, but we did anyway. These QRs feature a lever design reminiscent of our favorite Simplex SLJ downtube shifters, a knurled end cap for easy adjustment, and a brass external cam for durability. The axle is chromoly steel.

While they are designed to work perfectly with 135mm spaced hubs, you can use them on 130mm spaced hubs if you cut off the few mm of excess axle that sticks out.

• Compatible with disc brakes
• Size: 100 Front - 135mm Rear
• Comes as a lever set (front and rear) only
