The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobble stone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances like when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical Dual Control Levers so you don’t need to re-program your mind for a new system. Shimano Shadow RD The mechanism rear derailleur, SHIMANO SHADOW RD, is intended for more aggressive riding. Its super low profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance. https://www.icebikeheaven.com/shimano-r8050-di2-electronic-groupset-ultegra-r8050-derailleurs-road-bicycle-st-fd-rd-electronic-parts "🔥Pre order 5 to 7 working days Deliver to Malaysia, SG, Brunei, Worldwide (DHL) Accept Ewallet Boost TouchnGo Etc.. & 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 ☎ http://www.wasap.my/60174204398 Sales, Order, Customer service ☎ http://www.wasap.my/60195272398 After sales/ Warranty FOLLOW US ————— ✔ https://www.ebay.com/str/icebikeheaven37 ✔ https://shopee.com.my/icebikeheaven?tab=shop ✔ http://www.lazada.com.my/ice-bike-heaven/ ✔ https://fb.me/icebikeheaven ✔ https://www.instagram.com/icebikeheaven37/ 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 🥇♞ SSM Registered company- Icebikeheaven 🥇 7 Years of experience "
