- The Tech 4 uses all new internal sealing for reduced friction and the pivot spins on roller bearings, allowing the spring rate to be reduced. The lower spring rate in turn gives a lighter lever action, reducing rider fatigue and keeping our legendary feel and modulation - The updated V4 caliper utilizes hybrid style stainless steel pistons with a phenolic insert allowing for smoother movement and less maintenance, while still able to manage high temperatures without heat transfer during extreme use - Lever updated to provide a more ergonomic shape orientated to provide the best mechanical advantage during braking - Master cylinder includes reach and bite point control adjustability (BPC) and the piston is actuated by a cam and roller system to eliminate free play and friction - Split clamp is designed to reduce clutter and create more space for handlebar mounted devices (directly compatible with Shimano I-Spec shifters) - One piece 4-piston caliper, CNC machined from a solid billet of 2014 T6 aircraft spec aluminum alloy increases caliper stiffness for better efficiency. Increased pad surface area and more machining for better heat management and pad life - Includes: lever assembly, pre-bled (black) hose with stainless fittings, (74mm) caliper - Black plastic hose comes standard. Use HT1050 for upgrade to braided stainless steel hose - Hose is pre-cut to front/rear lengths (950mm front, 1500mm rear) but do not include extra fittings if lines need to be trimmed or internally routed. Use HT1035 (olive), HT1036 (insert), and HT1037/8 (copper washer) - Please note: The V4 caliper is not compatible with all direct mount 180mm forks due to the large piston design and variation in mount positions. We recommend running the V4 caliper with the correct mount and a 200mm rotor in this application - *Rotors and adapters sold separately Kit Weight Left/Front 350g Right/Rear 360g
