The derailleur hanger extension is a unique device that offsets the position of your road derailleur to make it possible to run a wide-range mountain bike style cassette. It is an ideal solution for riders looking to convert their road, gravel, cyclocross, or commuter drivetrain bike to attain the simplicity and reduced weight of a single front chainring but without giving up the gear range of a double. It is also great for riders with double chainring bikes that want lower gearing for those ultra steep climbs. It does not compromise the shifting in the smaller cogs of the cassette but yet it enables the derailleur to work with as large as a 50T cassette. Easy to install in less than 5 minutes Material - 6061 aluminum Bike Type: Road Biycles / Mountain Bikes Packcing included:1 Pcs FOR Wide Ratio Cassettes Weight :about 11.4g https://icebikeheaven.com/mtb-rb-rear-hanger-derailleur-extension-extende42t-46t-50t-cassette?search=goat ♥ NEW ARRIVAL & READY STOCK ♥ Deliver to Malaysia, SG, Brunei, Worldwide Accept RM SGD Paypal 3.9%, Credit card How to Order —————— 1.Product Option: 2.Quantity: 3.Color: 4.Name: 5.Address: 6.Contact number: Send to ☎FB http://m.me/icebikeheaven ☎ www.wasap.my/60174204398 FOLLOW US ———————— ✔ https://shopee.com.my/icebikeheaven?tab=shop ✔ https://fb.me/icebikeheaven ✔ http://www.11street.my/store/ibh ✔ http://www.lazada.com.my/ice-bike-heaven/ ✔ http://www.lelong.com.my/merchant/icebikeheaven.htm Buy from Us! —————————————————— 🚴🏻💯% POSITIVE FEEDBACK 🚴🏻💯% Warranty & After Sale Service 🚴🏻💯% PARCEL ARRIVAL GUARANTEED 🚴🏻💯% ❌hidden charges 🚴🏻 7️⃣ days size exchange 🆗 🚴🏻 7️⃣ days 100% 💲💲 Guarantee back ☄Prompt response 🥇♞ Registered SSM company- Icebikeheaven 🥇 3️⃣ Years of experience Become a dealer Want to start a business?
