Finishing kit, hangers, axles, wheels and accessories, and what fits.
ERE Research is our wheel partner. A Swiss-origin performance cycling component brand, founded in 2017, with a founding team carrying prior product development experience from across the biggest names in the industry.
We chose ERE after extensive testing across the wheel market. They came out on top on performance. All Pearson complete bikes are fitted with ERE wheels as standard.
Wheel specification varies by model and build tier.
ERE Research offers a lifetime warranty on manufacturing defects for the original registered owner. Register your wheels within 60 days of purchase to activate this. The ERE lifetime warranty is not transferable to subsequent owners.
ERE also offers a 50% crash replacement discount on a damaged wheel for the registered owner.
Yes. Spares specific to your build, including rear mech hangers and Pearson-branded contact point components, are available through My Bike Room. For groupset components, contact your local Shimano or SRAM dealer.
Pearson-branded components (the carbon one-piece cockpit on the Shift 2.0, the Pearson stem, handlebars, and seatpost across the range) are specced and branded by Pearson. They are manufactured to Pearson's specification.
Fizik saddles are fitted across the range. The specific model varies by build tier. If saddle fit is something you want to address specifically, that is one of the contact-point adjustments we can make based on your bike fit data.
Vittoria tyres are fitted across the range. On road builds: Vittoria Corsa Pro or Corsa NEXT. On gravel builds: Vittoria Terreno series. Vittoria are a considered choice, not a compromise. The team rides Corsa Pro themselves.
Current builds are set up with inner tubes. Tyres and rims are tubeless-compatible, so conversion is possible. Contact us for specific tubeless setup guidance for your build and wheel combination.
It is the small, replaceable link between your frame and rear derailleur, designed to bend or break in a crash so the frame does not. Because it is sacrificial, it is well worth keeping a spare so a bent hanger never cuts a ride short.
The right part depends on your model and its year. Each listing states the Pearson models and years it fits. If you are unsure, send us your frame details and we will identify the correct part.
A standard hanger bolts to the frame and the derailleur attaches to it, while a direct mount hanger interfaces directly with compatible derailleurs. Your frame and groupset determine which you need; the listing states which fits.
Each hanger carries a stamped reference. The Forge hanger is stamped 339. The shared Shift and On&On direct mount hanger carries two numbers, 358 and 369; both are on the same hanger, so either one confirms you have the right part. If you are unsure, send us a photo and we will check.
Compatibility is listed in the key features for each part, covering the Shimano and SRAM groupsets it suits. If your setup is not listed, get in touch and we will check it for you.
The On&On Race uses a UDH (universal derailleur hanger) only; it does not take a standard or direct mount hanger. It suits SRAM RED XPLR and Shimano GRX RX827 Di2 setups.
The On&On Adventure ships with the standard mount hanger, which suits Shimano GRX RX820 1x and RX825 Di2. If you run RX825 Di2, it can also be used with the direct mount hanger by removing the link on the derailleur.
Of course. Send us your model, year and groupset and our workshop will confirm exactly which hanger or axle you need before you order.
Each part lists the Pearson models and model years it suits in the description and key features. If you are unsure, send us your frame and model year and we will confirm the right part before you order.
Many of our cockpit and finishing parts use standard fittings, such as a 1 1/8 inch steerer, so they work on a wide range of frames. Check the key features for the exact standard, and ask us if you need to be certain.
Where a torque figure applies it is listed in the key features. Carbon parts in particular should be fitted to the stated torque with a calibrated torque wrench to avoid damage. If in doubt, have a bike shop or one of our retail partners fit it.
Yes. Any good bike shop or one of our retail partners can fit it, and we’re happy to talk them through it. If you’re ordering a new bike, ask us and we can fit the part as part of your build.
Always fit carbon parts to the recommended torque, use carbon assembly paste where appropriate and avoid clamping outside the marked areas. Inspect them regularly and replace anything that has taken a hard knock.
Replacement parts come with the bolts and small fittings needed for a straightforward swap unless the description says otherwise. If anything is missing, contact us and we will put it right.
Yes. The carbon rims are tubeless ready: fit tubeless tape, valves and sealant for a fast, supple ride, or run inner tubes if you prefer.
They are built for 12mm thru-axles front and rear with centre-lock disc brakes, matching Pearson's carbon frames and most modern road and gravel bikes.
The freehub suits Shimano and SRAM groupsets. Tell us your drivetrain and we will set the wheels up with the correct freehub body before they ship.
Rim width and depth are listed in the specification for each wheelset, with recommended tyre sizes and the maximum rider weight. Ask us if you are unsure what to run.
The hubs run cartridge bearings that are straightforward to service or replace. Any good bike shop or one of our retail partners can do the work, or we can supply the parts if you prefer to do it yourself.
If you’re ordering a new bike, we fit and set up the wheels as part of your build, including tubeless. Otherwise any good bike shop or one of our retail partners can fit them, and we’re happy to advise.
