Frequently Asked Questions
How do I know which eye‑to‑eye size I need?
Measure your current shock from eye center to eye center and confirm stroke length, then match to the available Vivid Ultimate sizes (225x75, 250x75, 250x72.5, 250x70, etc.). If your frame uses a trunnion mount, choose the trunnion variant. When in doubt, check your bike manufacturer's shock spec sheet or contact Scenders with your frame model and year.
What do the bottomless tokens do and how many should I run?
Bottomless tokens increase spring progression and reduce bottoming by effectively decreasing usable air volume. Start with the default token count supplied (commonly 1–2 depending on variant) and add or remove tokens based on how often you feel harsh bottom‑outs; aggressive riders or heavier riders typically add tokens, while lighter riders remove them for a plusher feel.
How does Adjustable Bottom Out (ABO) affect ride feel?
ABO adjusts hydraulic cushioning in the final 20% of travel without changing air pressure, letting you control how cushioned the shock feels on big hits. Use firmer ABO settings for aggressive, high‑speed tracks to prevent harsh bottom‑outs; use softer settings for more traction and a plush finish to the travel.
What maintenance does the Vivid Ultimate DH need?
Regular maintenance keeps performance consistent: perform air can and seal servicing at least annually or every 100–200 hours depending on conditions, and arrange damper servicing (internal) through an authorized SRAM/RockShox service center at longer intervals or when you notice performance changes. Always use correct torque on mounting hardware and keep bushings/bearings inspected and replaced when worn.
Is this shock compatible with my Trek Session 2022+?
Yes — there is a factory D1 configuration listed for Trek Session (2022+) that uses the 250x72.5 Vivid Ultimate DH variant. Confirm whether your frame expects the 250x72.5 length and standard eyelet mounting, and reference the SRAM Model ID RS‑VIVD‑UDH‑D1 or part number 00.4118.548.000 when ordering or arranging fitment.
Can I use this shock on non‑DH frames?
You can mount the Vivid Ultimate on frames that accept its dimensions and mounting standard, but it's tuned for downhill and will feel firmer and more controlled at high speeds. For lighter trail or all‑mountain bikes, consider shocks tuned for those disciplines to match travel and intended ride characteristics.
Buying Guide
When buying a downhill rear shock, confirm three things: correct eye‑to‑eye and stroke dimensions for your frame, the required mounting hardware (standard eyelet vs trunnion), and the desired spring/damping characteristics for your riding style. Count tokens and know whether your frame or riding weight needs a more progressive curve. Prioritize shocks with independent compression controls and a supple first stroke if you ride technical, high‑speed tracks. For racers and heavy hitters the combination of LinearXL air, RCT2 damper and adjustable bottom out offers the best balance of traction, support and tunability.
