Seek 430 FM FAQs

Can I fit Hope or Paul Klamper brakes?
The Seek 430 FM has been designed to accept a wide variety of Flat Mount brake calipers, including Hope RX4+. However, due to the specific cable entry angle on the Paul Klamper brakes, there's a very high risk the cable housing will interfere with the fork leg.
Can I run a rack?
You sure can! The Seek 430 FM does not have a crown mount, so you will have to find a rack that attaches to the axle (via the included Relaxle) and the fork leg instead - such as the "Elkhorn" or "Divide" racks from Old Man Mountain. A Tumbleweed T-rack is also a possible option.
I prefer a very upright riding position, how many spacers can I put under my stem?
As with most carbon steerer forks on the market, we do not recommend running more than 30 mm of spacers below the stem. We also suggest putting a 3-5 mm spacer above the stem to ensure precise compression and ample clearance of your stem cap.
What's the weight limit?
Our Seek 430 FM fork has been tested beyond ISO 4210 standards for MTB/offroad riding (120 kg). Our extended tests were performed with extra weights attached to each fork leg. As such, our max recommended system weight (rider, bike + gear) is 140 kg.
How do I fit the steerer expander plug?
The full length of the steerer expander plug should extend past the stack of the stem, so do not leave excess steerer above the stem other than for light riding while dialling in your fit.

The expanding feature of the plug consists of 3 wedges - it is extremely important that the gap between the wedges DO NOT line up with the gap at the back of the stem clamp. Failure to follow this advice can lead to damage to the steerer.
Are the leg mounts removable?
No, the mounts are bonded to the fork and are not user removable. The 6mm hex recess in the mounts is only there to ease factory assembly. Should a mount become damaged, please do not try to remove it yourself. Please contact us instead.
