What Our Gearhead(R) Experts Are Saying: "I like that these are available individually because it makes replacing a lost or damaged endcap easy. Fit and tolerances are spot-on, and once installed the hub runs exactly as it should. Just make sure you order one for each side to complete the conversion."When we're fine-tuning a front-end setup or replacing a missing piece, the Hydra 2 Boost Conversion Endcap makes it easy to keep our wheel in service. Instead of committing to a full kit, purchasing each endcap separately gives us the flexibility to replace exactly what we need while keeping our Hydra 2 hub ready for modern fork standards. Designed for Hydra 2 20 x 110 front hubs, this precision-machined endcap converts one side of the hub to a 15mm axle interface while preserving proper alignment and smooth rotation. To complete a full conversion, two endcaps are required-one for each side of the hub-making this a modular, service-friendly solution for evolving builds.
