| Will the Seek 430 PM work with my frame? |
The Seek 430 PM fork has a tapered 1 1/8"-1.5" (28.6-39mm) steerer with a 300 mm length. We use this steerer type on all of our forks. It may work with your frame, but you may have to change your headset or headset bearings to make it work. Please have a professional bicycle mechanic fit your Seek 430 PM fork.
|
| Will the Seek 430 PM work with 4-piston calipers? |
Yes, but in some cases, depending on how bulky the caliper is and how the pistons are configured, you may need to pair it with a +20mm adapter and a 200mm rotor.
If you want to fit a HOPE caliper, for example, their "HBML" adapter has been confirmed to work. |
| Will the Seek 430 PM work with Paul Klamper calipers? |
We have yet to test the fit with Paul Klamper brakes physically, but 3D modelling suggests it will work together with a +20mm Post Mount adapter and a 200mm rotor.

Can I run a rack?
|
You sure can! However, the Seek 430 PM 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. We do not recommend attaching rack support struts to a single M5 mount on the leg - use the OMM Fit Kit Pucks.
We can not keep a database of all the racks on the market and their compatibility with our forks. Please refer to the "General Dimensions & Cargo Mount Specs" entry in the "Tech Info & Manuals" section above to help you determine compatibility. |
|
Can I run a "Lowrider" Rack?
|
Not likely. We did not design this fork with such racks in mind, so the location of the leg mounts in relation to each other and the axle will likely not line up with the mounting points on the rack. Please refer to the "General Dimensions & Cargo Mount Specs" entry in the "Tech Info & Manuals" section above to help you determine compatibility. |
|
Can I run a Fred Bar?
|
No, the Fred Bar is not safe to use on a carbon steerer.
|
|
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 (40mm can be approved in certain cases). 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 PM 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.
|
|
How much can I carry on the fork legs?
|
The M5 rivnuts can carry 3kg across all three mounts. Please use a mounting cage that utilises all three mounts. If attaching something to only two of the mounts, the weight limit is reduced to less than 1kg. We do not recommend attaching water bottles to the fork.
|
|
What torque should I use for the leg mounts?
|
Generally, you don't need to add a lot of torque to the M5 bolts to secure a mounting cage. The maximum recommended torque to attach a cage is 5Nm.
DO NOT use locking washers, apply threadlocker or use bolts with threadlocker already applied. NOTE: If you're just putting bolts in the mounts to plug the holes - DO NOT torque the bolts. Only do them up finger tight. Please only ever use cargo cages where the baseplate is in contact with the flat surface of the mount. Otherwise, the M5 mount may start spinning, or maybe even pull out. |
Our non-suspension-corrected fork, complete with mounting points, so you can carry more on your next off-road adventure.
Bikepacking Companion
Our SEEK 430 fork, originally titled GMX+, was initially available to work in unison with the GMX+ frameset and our popular Walmer bar. Today it is now available as a non-suspension corrected alternative. Please note, the SEEK 430 is not designed to replace a suspension fork.
Ready For Adventure
Featuring 6 x 12 mm M5 mounting points on each blade, the SEEK 430 can accommodate anything from extra water bottles, our Rocket Pooches, or any other micro pannier or fork-specific bag. However, please keep in mind that it is designed to carry a max weight of 6 kg (3 kg/ blade across three mounting points). Furthermore, the Seek 430 Fork features the lowest possible axle to crown height, 430 mm, allowing frame builders to develop bikes accommodating wider tyres, with a clearance of up to 3.0 inches. With wider tyres, you can explore more rugged terrain with ease.

The remarkable Seek 430 FM bikepacking carbon fork
We have put a hell of a lot of work into the new Seek 430 FM fork to get it to where it is now. Our primary focus was to improve the load carrying capability of a carbon fork, but we managed to include a some other improvements, too...
