What's the I-Spec technology for:
By creating the I-Spec clamps, Shinano not only eliminated the clamp, but also brought a gain in ergonomy with controls closer to the fingers and easier to handle. There are several versions of the I-spec technology: A, B, II and EV
The latest evolution of the Shimano standard, I-spec EV provides greater flexibility in lever positioning to stay focused on riding.
The I-Spec EV components are only compatible between themselves.
This standard brings additional stiffness to the set by adding a point of contact between the end of the lever and the handlebar
The new Shimano seatpost control is I-Spec EV compatible which allows for a more ergonomic positioning similar to that of the shifters
The standard I-Spec II has a half shell that fits inside the brake collar (which is therefore clamped to the handlebars by the brake collar) on which the speed control is attached.
The I-Spec II components are only compatible between themselves.
How to differentiate:
I-Spec A : First generation, it is characterized by a threaded attachment with a small hook.
I-Spec B : It is a shorter threaded fastener without a hook unlike the first version.
An I-Spec A compatible brake can be used with an I-Spec A and B shifter, but an I-Spec B brake can only be compatible with an I-Spec B shifter.
Deore XT M8100 brakes have a new master cylinder with 2 points of support on the handlebars to provide a smoother braking feel. The levers also have the adjustment knob on the guard and the adjusting screw for the dead stroke of the lever, so that you can adjust the brakes, even while exiting.
The 2-piston sorting system for XC use adopts the same design as the XT M8000 tri-sorters, which means that the pads in G02A / 3A / J02A / 3A or G04S / J04C are compatible, while 4-piston version has been completely redesigned, and uses the construction of the XTR M9100.
