This is the Hope Stealth Tech M4 EVO Front Brake Set with Braided Hose. For 2012 the lever pivot has been slightly shortened which translates to a 15% increase in power. The Tech Evo lever now has a roller fitted to the cam mechanism, further enhancing the smooth feel of the lever. Ambidextrous 'flip flop' design, CNC machined from a solid billet of 2014 T6 aircraft spec aluminium alloy - with a split clamp to allow easy set up and choice of positioning. Redesigned piston, lever and pivot assembly with external 'on the fly' reach and bite point adjustment dials. The lever linkage eliminates freeplay in the lever giving a consistent and reliable feel to the brake. Further developments include bearing lever pivots for smooth, rock free use and increased lever ergonomics with a perforated lever for extra grip and feel. Also, a double sided reservoir lid makes for easy bleeding. The brake is supplied with a Goodridge stainless steel braided hose.
The one piece caliper is CNC machined from a solid billet of 2014 T6 aircraft spec aluminium alloy. The M4 caliper uses four identical 16mm phenolic pistons which gives more usable power to the brake, whilst keeping their legendary ''feel''. A drip free bleed nipple and wide angle orientation of the fluid inlet connector have also been added, allowing for neater hose routing and cleaner servicing
