Review: I use this on my single speed cyclocross bike on the freewheel side of my flip flop hub. It has very slightly higher rolling friction than the stock freewheel, it will ghost pedal as you roll the bike. It isn't an issue as far as coasting speed, however. It has a good sound, not too loud but definitely audible. Super sturdy, works really well with 1/8 inch chain. I recommend this freewheel, it is a super good value. ## Features - Three-pawl design provides engagement every 12 degrees (30 steps total) - Cold forged for high-torque strength, and increased durability - Fits Standard 1.37" x 24tpi hub threads - Removable with standard 4-prong tool ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071FS1V8P | | Batteries included? | No | | Best Sellers Rank | 562,536 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 1,056 in Cassettes & Freewheels for Bikes | | Brand | ACS | | Color | Silver | | Customer Reviews | 4.2 4.2 out of 5 stars (56) | | Date First Available | 1 Jun. 2017 | | Department | Does Not Apply | | Height | 1 inches | | Included components | freewheel | | Is discontinued by manufacturer | No | | Item display length | 3 inches | | Item display width | 3 inches | | Item model number | 63858-0000 | | Manufacturer | Hawley LLC | | Material type | Chromoly Steel | | Number of items | 1 | | Product Dimensions | 8.38 x 8.38 x 2.79 cm; 204.12 g | | Sport | Cycling | | Style | Does Not Apply | ## Product Details - **Brand:** ACS - **Exterior finish:** Nickel Plated - **Global Trade Identification Number:** 00816411002423 - **Item diameter:** 1.37 Inches - **Item weight:** 204 g - **Material:** Chromoly Steel - **Pitch circle diameter:** 0.04 Inches - **Rim size:** 1.37 Inches - **UPC:** 816411002423 - **Vehicle service type:** Bicycle ## Images ![BMX Paws 4.1 BMX Freewheel,18T - Image 1](https://m.media-amazon.com/images/I/51I5iK-M97L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***. on 18 August 2020* Es un producto de excelente calidad y cumple mis expectativas!!!! ### ⭐⭐⭐⭐⭐ Review *by J***N on 20 July 2019* I use this on my single speed cyclocross bike on the freewheel side of my flip flop hub.
