Product Details

Overview & Technology

RockShox Bottomless Tokens (35mm DPA) are precision-molded inserts that change the air spring volume in Dual Position Air forks to shape mid-stroke support and bottom-out progression. Sold as a 3-piece kit, these tokens let you add controlled ramp to your fork's curve without changing spring pressures or damper settings. Manufactured from high-strength acetal/Delrin-style material, the tokens resist compression set, friction and wear inside the air sleeve. They work with RockShox DPA (Dual Position Air) systems and are assigned SRAM model ID: FS-SPP-A0 (Mfg. part #: 11.4018.032.004, Product #942003).

Key Features & Real-World Benefits

Fine-tune progression: Adding 35mm tokens increases spring progression and mid-stroke support so the fork feels more planted on square-edge hits and heavier landings, while providing a predictable ramp into bottom-out. This is especially useful for riders who want firmer mid-stroke without losing sensitivity on small bumps. • 3-piece kit — install 1–3 tokens to dial progression incrementally. • Delrin/acetal construction — long-lasting, low friction, and dimensionally stable. • Optimizes for Pike A1/A2, Lyrik B1+, Yari A1+, ZEB and other DPA forks.

Fit, Compatibility & Installation Notes

The 35mm Bottomless Tokens are designed for RockShox Dual Position Air forks: Pike A1–A2, Lyrik B1+, Yari A1+, ZEB and similar DPA air springs. Confirm your fork uses the DPA air spring and compatible upper/lower leg internals before purchase — tokens will not fit non-DPA or older single-chamber air springs. Installation is straightforward for a competent home mechanic: remove the air spring (follow RockShox service manual), insert tokens into the air sleeve, reassemble and set sag/air pressure. Always work on a clean bench, use recommended seal grease, and torque per manufacturer specs. If you're unsure, have a qualified shop fit them — improper installation can affect fork performance and safety.

Who Should Use These Tokens

These tokens are ideal for mountain riders who want more mid-stroke support and predictable bottom-out without changing damper settings or adding high-pressure spacers. Trail, enduro and aggressive all-mountain riders benefit most — especially heavier riders, bikepackers with loads, or anyone riding aggressive lines who wants a firmer feel through larger impacts. If you’re chasing plush small-bump compliance only, start with suspension setup and low-speed compression adjustments first. Tokens are best used when you need added support through mid-stroke and end-stroke without compromising sensitivity.

Frequently Asked Questions

What do bottomless tokens actually do?

Bottomless tokens reduce air spring volume which steepens the spring curve. That gives more mid-stroke support and a firmer ramp into bottom-out without changing damper settings, helping the fork feel more planted on big hits.

How many tokens should I install?

The kit includes three tokens; you can install 1–3 depending on how progressive you want the spring. Start with one token and test ride, then add more if you need additional mid-stroke support or bottom-out resistance.

Are these compatible with my fork model?

They fit RockShox forks that use the Dual Position Air (DPA) spring such as Pike A1/A2, Lyrik B1+, Yari A1+ and ZEB. Verify your fork's air spring type in the service manual or on the seal head; tokens will not fit non-DPA or older single-chamber springs.

Can I install them at home or need a shop?

A competent home mechanic can install tokens if they follow the RockShox service manual and use basic tools. If you’re unfamiliar with air spring disassembly or torque specs, have a professional do the job to avoid damage or safety risks.

Do tokens affect rebound or damper function?

Tokens change only the air spring volume — they do not modify the damper’s internal circuits. However, because they alter spring characteristics, you may want to re-tune rebound and compression settings for best balance between support and compliance.

What material are the tokens made from and will they wear?

These tokens are molded from a high-strength acetal (Delrin-like) plastic chosen for dimensional stability and low friction. Proper installation and clean internals minimize wear; inspect during routine fork service.

Buying Guide

When choosing bottomless tokens, match the token length and profile to your fork's air spring type. For RockShox DPA forks the 35mm token is a popular mid-stroke tuning option — buy the 3-pack to experiment with 1–3-token setups and find the feel you prefer. Consider rider weight, typical terrain and whether you need small-bump sensitivity or mid-stroke support most. Lighter riders often need fewer tokens; heavier or more aggressive riders typically benefit from multiple tokens. Always follow the fork manufacturer's service guidance when installing tokens.
