The Arch MK4 is the wheelset a lot of us here at Stans choose to ride. All-mountain, Downcountry, Trailduro—whatever they're calling it this week, when you like pushing your limits on climbs, descents, and every kind of trail, this is your wheelset.
The Arch MK4's 28mm internal width and patented lightweight, low-profile design is not afraid to climb, while being an absolute monster on the descents. With a welded seam, reinforced spoke bed, and durable 6069 aluminium construction, the Arch MK4 rims give you the confidence to ride everything. When it comes to a consistent and reliable airtight tubeless seal, nothing beats Stans patented Bead Socket Technology. The Arch MK4 rims feature an asymmetric design with offset spoke holes to improve spoke angle and create a stronger all-around wheel. Unlike most asymmetric rims that suffer from difficult inflation and poor tubeless performance, Stans BST-Asymmetric design delivers all the advantages of a stronger wheel, with no compromises in tubeless performance. Nobody likes downtime, so the Arch MK4 wheelset is built with traditional J-bend spokes based on their proven strength, ride quality, and easy serviceability. Stans has always made it easy to find replacement spokes should you ever damage your wheel, and now we've made it even easier. MK4 front and rear wheels of the same diameter all use the exact same very common spoke length, both sides, front and rear. Serviceability doesn't get any easier than that.
From the first click of the incredible M-pulse hubs, it's clear that confidence is the philosophy behind every part of this wheelset. Designed and CNC machined by Project321 in Bend, Oregon, M-pulse freehubs feature 6 pawls with Neodymium magnets that lock into place with greater force than conventional pawl springs but offer virtually no resistance when coasting. Multiple teeth on each pawl offer better load distribution for years of trouble-free riding, and the angle of the pawls was engineered to transfer stress away from the rotating bearings, decreasing stress and wear on the entire freehub. That durability extends to the 17mm axles machined of 7075 aluminium and the full complement of Enduro brand bearings, including a double-row freehub bearing. M-pulse internals are also fully shielded inside the hub, because the only thing better than a good bearing seal is a good bearing seal most dirt can't even reach. As durable as they are, these hubs are also built for speed. M-pulse hubs engage with only 1.66°of rotation, putting down power nearly instantaneously, but how smoothly these hubs roll is what really stands out. Adjustable preload allows you to fine-tune M-pulse hubs for reduced friction, and less drag means more speed on the ground. The result is a bombproof hub with quick, consistent engagement and less resistance for more speed.
Available with Shimano Micro Spline, HG, or SRAM XDR freehub, and 6-bolt or Centerlock brake style, with options to fit all popular axle configurations.Tubeless ready with rim tape installed.
The Arch MK4 is their most versatile wheelset, and the best aluminium wheelset available for riders who want to push limits on every trail. Up, down, and wherever the ride takes you, the Arch MK4 wheelset has it under control.

At Triton Cycles we aim to make returns as straightforward as possible.
If you purchase an eligible item online, you have 14 days from receiving your order to notify us that you wish to cancel it. Once you have notified us, you then have a further 14 days to return the goods.
The quickest and easiest way to arrange a return is to log into your Triton Cycles account, open the relevant order and select the returns option. This records the return against your order and helps us process it more quickly when it arrives.
If you are unable to arrange your return through your account, please contact us before sending anything back.
For a full refund, products should be returned in a condition consistent with reasonable inspection and, wherever possible, complete with their original retail packaging, internal packaging, accessories, manuals and fittings.
Please do not write on manufacturer packaging, attach courier or postage labels directly to it, or use branded product packaging as the outer shipping box. Please place the product inside a suitable mailing bag or separate outer box.
If an item has been fitted, installed, used or handled beyond what would reasonably be necessary to inspect it, and this has reduced its value, we may make an appropriate deduction from the refund.
Unless an item is faulty, damaged or has been supplied incorrectly, return shipping costs are the responsibility of the customer.
If an item arrives damaged, is faulty or is not the item you ordered, please contact us before returning it. Retain all packaging and, where possible, provide photographs showing the item and any damage. In many cases we may be able to resolve an issue without requiring the complete product to be returned.
If you believe that an item may be faulty or require a warranty claim, please contact us first rather than booking it as a standard return. Our experienced team or workshop may be able to diagnose the issue remotely or advise on the quickest way to resolve it.
Lithium-ion batteries, including e-bike batteries, are subject to special transport restrictions and should not be returned using an ordinary postal or courier service without first contacting us.
Bicycles purchased online may be returned in accordance with your applicable statutory rights. Please contact us before returning a bicycle so that we can advise on the appropriate return method. Collection costs for change-of-mind bicycle returns will normally be payable by the customer.
For bicycles purchased and collected in-store, we do not accept returns simply because you have changed your mind. Exchanges on unused items may be considered at our discretion where a suitable alternative is available.
International return shipping and any reverse duties or taxes are the responsibility of the customer unless otherwise agreed. Original delivery charges are not refunded where an international order is returned because customs or import charges have not been paid.
