Thinking that going to spring system will allow me ride for much longer than that! The ride was and is great but the sound is not! ## Frequently Bought Together - catazer RCP2S Downhill Bicycle Metal Rear Suspension Spring Shock 190mm 200m 220mm 240mm 550 Lbs MTB Bike Rear Shocks (190mm*550lbs) - 31.8 Stem 45mm Bike Stem Wake Mountain Bike Stem Short Handlebar Stem for Most Bicycle, Road Bike, MTB, BMX, Fixie Gear, Cycling (Aluminum Alloy, Black Blue Gold Red) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/456459014-rcp2s-downhill-bike-metal-rear-suspension-spring-shock-190mm-550lbs](https://www.desertcart.hr/products/456459014-rcp2s-downhill-bike-metal-rear-suspension-spring-shock-190mm-550lbs) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-19*
