Oversized Pulley Wheel System - Shimano
Developed to answer the increasing needs for watt savings and performance equipment. The system consists of 17-tooth alloy pulley wheels fitted with low friction CeramicSpeed Bearings and a lightweight cage made from a polyamide and carbon fibre finish.
The OSPW system reduces friction in the pulleys by 60% and for your optimised performance, your watts savings start at 2.4 watts.
This NEW revolutionary OSPW System is developed, produced and assembled by hand in Denmark. This plug-and-play product is the result of an in-depth development process and has been designed for optimal performance. Created to answer the needs for less friction - as much as 60 %, increased speed and a more efficient drivetrain.
This OSPW System is the true advantage that helps you to comfortably ride any distance. The optimisation of your drivetrain with the new CeramicSpeed OSPW System delivers access to the industry leading efficiency with watt savings that start at 2.4 watts. The high quality of the cage material and the CeramicSpeed bearings inside the pulleys offer you an extreme longevity, which is 3-5 longer than other commonly used pulley wheels on the market.
Like all other products delivered by CeramicSpeed, this product has also undergone a thoroughly test program. We are proud to say that professional triathletes like Tim Don and Tyler Butterfield are amazed of the new pulley wheels system and have a great feedback for the product.
Please note that the OSPW system does not fit a Canyon Speedmax CF, due to the design of the gear drop and rear triangle.
IMPORTANT: When travelling, please remember to dismount your entire rear derailleur with an Allen key, as the OSPW System will not fit in most bike travel bags.
Maintenance It's important that you properly lubricate your bearings in order to ensure optimal performance and maximum longevity. Add oil to the outside of the bearing seal, so that oil can penetrate the bearing. Do this when you lubricate your chain, or if you have washed your bike or have been riding in wet or muddy conditions.
Available with black or red pulley wheels and 607 or 607 coated bearings for extended durability and longevity of the product.
This specific system is compatible with Ultegra 6700/6770/6800/6870 mechanical and Di2 rear derailleurs and Dura Ace 7900/7970/9000/9070 mechanical and Di2 rear derailleurs.
The system is compatible up to a 28tooth cassette on most bikes depending on derailluer hanger.
