Tire-to-rim compatibility
ENVE
Use the exact wheel family and generation. ENVE identifies rim construction and tire requirements, and distinguishes listed approval from tires it has not tested.

What are you
changing?
Build the whole parts recipe: your bike, the new component, the parts you will keep, and the connections between them.
Start with your bike’s make, model, year, frame size and riding style. Photograph the model numbers on existing parts. These guides help you assemble the questions and manufacturer evidence for your setup; they are not an automatic fit checker.

A complete wheel upgrade.
Replacing wheels, changing tires or building from hubs and rims? Work through the connections in order. Keep the parts you plan to reuse on the same list as the new ones.
| Connection | Collect & compare | Complete the recipe |
|---|---|---|
| Bike → wheel | Write down frame and fork make, model, year and size. Record front and rear wheel size, axle diameter and spacing separately. Compare with the exact wheel SKU. | Keep the bike manuals beside the wheel specifications. Ask about approved end caps or conversions if the interfaces differ. |
| Hub → cassette | Record the cassette model, gearing and required freehub/driver. Check the selected rear hub variant. | Carry the cassette choice into the chain, derailleur and shifter check. Include any specified spacer, lockring or replacement driver. |
| Hub → brakes | Compare rotor attachment, rotor size and thickness, brake model and the frame/fork requirements. | Identify the required rotor hardware and any documented adapter. An attachment match alone does not confirm the complete brake setup. |
| Rim → tire | Identify rim model/generation, internal width and hooked or hookless construction. Record the exact tire model, size and construction. | Check both makers’ guidance, pressure limits and bike clearance. Keep a suggested tire-width range separate from approval of an exact tire. |
| Tire → tube | Use the tire’s size marking to select the tube size range. Check valve type and usable valve length for the rim. | Bring a suitable pump and repair supplies. Using a tube does not override the rim maker’s tire requirements. |
| Rim → tubeless setup | Check rim and tire suitability together, then identify the specified tape, valve and sealant. | List tape width, valve length, inflation equipment and repair supplies before ordering; check what the wheel actually includes. |
| Hub + rim → spokes | For a custom build or repair, identify the hub and rim variants, hole counts, lacing and spoke/nipple specifications. | Have the builder specify spoke lengths and tension requirements for that assembly. Keep replacement part numbers with the wheel record. |
| Finished wheel → riding | Compare intended use and published load limits with the rider, bike and planned use. | Include installation, brake adjustment and follow-up service in the quote. Record unresolved fit questions before buying. |
Use the manufacturer resources below for exact model specifications. This is a planning checklist, not a whole-bike compatibility result.

Start with the tire dimensions, then choose the valve and tube variant. A tube selection does not by itself approve a tire/rim combination.

Seatpost & dropper fit.
For a rigid post or dropper, begin with the frame and your riding position. For a dropper, check usable travel only after diameter, height and insertion are known.
| Connection | Collect & compare | Complete the recipe |
|---|---|---|
| Frame → post diameter | Identify the frame’s specified seatpost diameter and the proposed post diameter. Confirm the frame model, year and size. | If a shim is proposed, obtain approval for the exact frame/post arrangement. Do not confuse seatpost diameter with seat-clamp diameter. |
| Rider → saddle height | With the saddle at your riding height, record collar-to-saddle-rail height in millimeters using the chosen manufacturer’s measurement points. | Keep saddle position and rail dimensions in the record. A different saddle or clamp can change the height relationship. |
| Frame → insertion | Determine usable insertion from the frame guidance and the post maker’s method. Note internal obstructions and routing space. | Compare both frame and post minimum-insertion requirements with the proposed installed position. Nominal seat-tube length is not a usable-insertion measurement. |
| Available height → dropper travel | Compare the exact diameter, generation, travel, total length and collar/head dimensions in that model’s chart. | Use FOX, PNW or OneUp’s own calculator/chart for the post being considered. Equal advertised travel does not establish equal fit. |
| Post → actuation & controls | Identify internal/external routing or wireless actuation, the compatible remote and its mounting hardware. | Include cable/housing or required battery/charger. Check room beside the brake lever and shifter, plus operation through steering movement. |
| Post → saddle | Record saddle rail shape, dimensions and material, then check the post’s clamp instructions. | Include model-specific clamp hardware if required. Preserve the saddle’s adjustment limits. |
| Assembly → service | Keep installation instructions, specified torque values and maintenance requirements for the frame, post, remote and saddle. | Price the complete installation and service needs, not just the post. Obtain help with measurements that remain uncertain. |
Compare equivalent measurements. FOX’s Transfer guide checks ride height and insertion together. PNW supplies a calculator for each post model. OneUp also accounts for insertion and routing clearance. Follow each tool’s measurement instructions; do not transfer a result to another brand or generation.

Changing gearing? Follow the whole system.
List your shifter, derailleur, cassette, chain, chainring, crank, bottom bracket and rear hub by exact model. Note speed count, cassette range, chainline, crank spindle and frame interface. Use the manufacturer chart for the intended combination, including required firmware or electrical components where applicable.
Ask which existing parts can remain, which must change together, and which tools or adapters the installation requires. Matching the number of speeds alone is not a compatibility finding.

Suspension starts with the frame.
For a fork, collect the frame’s requirements and the proposed wheel size, travel, axle, steerer and installation dimensions. For a shock, collect the exact frame model/year and its specified shock dimensions, mount and hardware. Obtain frame-maker guidance before choosing a different configuration.
Identify the component by model or serial number, then use its installation and setup documents. A pressure or sag recommendation does not establish fit.
