A popular upgrade for Razor MX350 / MX400 / SX350 etc. rear disc brakes, pocket mods, BMX, single speed, motorized bike and trike builds - CHECK FIT BEFORE YOU ORDER: Works only if your hub has exposed outer threads. NOT for Center Lock hubs, hubs that already have 6 bolt holes, cassette/freehub hubs, or smooth hubs with no threads. Your frame or fork also needs a disc caliper mount or caliper bracket - WHAT "44MM" MEANS: 44mm is the rotor bolt circle (standard IS 6-bolt), NOT the hub size. Inner thread: standard freewheel thread 1.37" x 24 TPI, bore approx. 33.7mm. Thickness 7.5mm, 15g each. Fits any 6-bolt rotor. Please compare with the dimension chart before ordering - EASY TO INSTALL, 2 PER PACK: CNC-machined aluminum alloy. Clean and lightly grease the hub threads, start threading by hand and tighten until seated; add thread-locker for extra security. If it does not turn smoothly, stop and check the thread size. Do not force it. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08RWK1B2Q | | Best Sellers Rank | #44,592 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #4 in Bike Brake Mounts & Adapters | | Brand | Juscycling | | Brand Name | Juscycling | | Compatible with Vehicle Type | Bicycle | | Customer Reviews | 4.2 out of 5 stars 268 Reviews | | Exterior Finish | Aluminum | | Manufacturer | Juscycling | | Material | Aluminum | | Material Type | Aluminum | | UPC | 710050419690 | | Vehicle Service Type | Bicycle | ## Product Details - **Brand:** Juscycling - **Exterior Finish:** Aluminum - **Manufacturer:** Juscycling - **Material:** Aluminum - **UPC:** 710050419690 - **Vehicle Service Type:** Bicycle ## Images ![Freewheel Threaded Hub Disc Brake Rotor Adapter, 2 Pack 6 Bolt Flange (44mm Bolt Circle), Compatible with Razor MX350 MX400 SX350, BMX, Single Speed & Motorized Bikes - Image 1](https://m.media-amazon.com/images/I/61ddd2w7ryL.jpg) ![Freewheel Threaded Hub Disc Brake Rotor Adapter, 2 Pack 6 Bolt Flange (44mm Bolt Circle), Compatible with Razor MX350 MX400 SX350, BMX, Single Speed & Motorized Bikes - Image 2](https://m.media-amazon.com/images/I/41RbNn-ijAL.jpg) ![Freewheel Threaded Hub Disc Brake Rotor Adapter, 2 Pack 6 Bolt Flange (44mm Bolt Circle), Compatible with Razor MX350 MX400 SX350, BMX, Single Speed & Motorized Bikes - Image 3](https://m.media-amazon.com/images/I/31mneiIJHTL.jpg) ![Freewheel Threaded Hub Disc Brake Rotor Adapter, 2 Pack 6 Bolt Flange (44mm Bolt Circle), Compatible with Razor MX350 MX400 SX350, BMX, Single Speed & Motorized Bikes - Image 4](https://m.media-amazon.com/images/I/31BxqO4Ej0L.jpg) ## Frequently Bought Together - Bicycle Bike Freewheel Threaded Hubs Disk Disc Brake Rotor 6 Bolt Flange Adapter 44MM， 2 pcs/Pack - BBR Tuning Billet Aluminium Disc Brake Adapter - Disc Brake Caliper Bracket - Bicycle Disc Brake Conversion - Rear Disc Brake Adapter Kit - Teyssor 140mm 160mm 180mm 203mm Bike Disc Brake Rotor with 6 Bolts Fit for Road Bike Mountain Bike BMX MTB --- ## 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.gr/products/273927891-freewheel-threaded-hub-disc-brake-rotor-adapter-2-pack-6](https://www.desertcart.gr/products/273927891-freewheel-threaded-hub-disc-brake-rotor-adapter-2-pack-6) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-24*
