SR Suntour Q-Loc II Thru Axle - Front

Tool-free thru axle for SR Suntour forks.

Q-Loc II is SR Suntour's own axle system — an expanding collet that locks into the fork leg and releases with a lever, so you get thru-axle stiffness with quick-release convenience. No 6mm hex, no threading it back in at the trailhead.

This is the 15 x 110mm Boost version, part FKA100-25, in chromoly.

Specs

• Spacing: 15 x 110mm Boost, front
• Material: Chromoly
• Weight: 128g
• Part number: FKA100-25

Will it fit my fork?

Check the compatibility chart in the product images — it maps every Q-Loc part number to the forks it fits. Two quick checks you can do at home:

• Look for a 15 x 110 sticker on the fork's lower leg.
• Measure between the inside faces of the dropouts — it should be 110mm.

If your fork is 15 x 100mm rather than Boost, you need a different Q-Loc axle. Bring the fork or a photo of the lower leg into Midway or Heber and we'll confirm before you buy.

Heads up

The Q-Loc collet is a wear item. If yours stopped releasing rather than snapping in a crash, replacing the axle usually solves it — and it's worth keeping the fork's dropout bore clean and lightly greased so the next one lasts longer.
