No new hub or wheelset needed, just add a rotor and a caliper - APPLICATIONS: Designed to turn freewheel-threaded wheels into disc brake wheels. Successful applications include kids electric and mini dirt bikes, pocket mods, eBikes, BMX, beach cruisers, trikes, tandems, motorized bicycles, rat rod and single speed builds. If your hub has freewheel threads, it is worth a look - WORKS WITH ANY 6-BOLT ROTOR: 44mm (1.73") is the rotor bolt circle, so standard 6-bolt rotors in 140, 160, 180 or 203mm bolt straight on. Bore approx. 33.7mm / 1.33", thread 1.37" x 24 TPI, thickness 7.5mm (0.30"), 15g each. - 2 PACK, MORE OPTIONS: Build two wheels, keep a spare, or stack the second adapter as a 7.5mm rotor spacer to move the rotor outward when your hub threads are long enough. Not for Center Lock or cassette hubs, or hubs without threads. Your frame or fork also needs a disc caliper mount - INSTALL TIPS: CNC-machined aluminum alloy. A snug fit is normal: clean the hub threads, add a little grease, start by hand and tighten until seated. If it will not turn smoothly, stop and check the thread instead of forcing it. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08RWK1B2Q | | Best Sellers Rank | #53,440 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #6 in Bike Brake Mounts & Adapters | | Brand Name | Juscycling | | Compatible with Vehicle Type | Bicycle | | Customer Reviews | 4.2 4.2 out of 5 stars (273) | | Exterior Finish | Aluminum | | Manufacturer | Juscycling | | Material Type | Aluminum | | UPC | 710050419690 | ## Product Details - **Brand:** Juscycling - **Exterior Finish:** Aluminum - **Manufacturer:** Juscycling - **Material:** Aluminum - **UPC:** 710050419690 - **Vehicle Service Type:** Bicycle ## Images ![Bike Disc Brake Adapter, 2 Pack Freewheel Threaded Hub to 6 Bolt Rotor Flange, 44mm (1.73") Bolt Circle, Screw-On Disc Mount - Image 1](https://m.media-amazon.com/images/I/61ddd2w7ryL.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.sk/products/273927891-bike-disc-brake-adapter-2-pack-freewheel-threaded-hub-to](https://www.desertcart.sk/products/273927891-bike-disc-brake-adapter-2-pack-freewheel-threaded-hub-to) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-12*
