Functionally, XT SM-RT86 Disc Brake Rotors stop equally in comparison to Shimano's apex XTR line. That's because of Ice Tech, a shared technology on both models. The difference between the two lies in a slightly lighter XTR spider that's reserved for gram-obsessed racers. In reality, most of us aren’t going to feel the benefits of a few grams lost when they're so centrally located to the hub. However, what we are going to profit from is the three-piece Ice Tech Rotor. It is essentially two pieces of steel optimized for friction sandwiched over an aluminum core. This means Shimano is utilizing the high thermal conductivity of aluminum, where other manufacturers solely use steel throughout the braking surface. Additionally, the quicker cooling alloy core more efficiently transfers heat to the alloy spider. The resulting cooler operating brakes will last longer and provide more consistent stopping in the most trying conditions. Additionally these rotors are compatible with SLX and Deore calipers if you'd like to upgrade existing brakes. Shimano's XT Ice Tech 6-Bolt Disc Brake Rotor SM-RT86 are available in three sizes -- 160, 180, and 203mm. Aluminum core sandwiched between steel faceplates conducts heat away from the brake 160, 180, and 203mm options Six-bolt mounting https://icebikeheaven.com/shimano-xt-sm-rt86-rotor-6-bolt-rt81-central-lock-ice-tech-brake?search=rt86 Deliver to Malaysia, SG, Brunei, Worldwide (DHL/ Aramex) Accept RM / SGD via Paypal 3.9%, Credit card 0% 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 ✔ http://www.lelong.com.my/merchant/icebikeheaven.htm ✔ 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 🥇♞ Registered SSM company- Icebikeheaven 🥇 5 Years of experience Want to earn extra income up to rm1000-2000 per month? pm us to do part time dropship
