The new Hope T4 Evo lever blades fit the standard T4 master cylinder. I haven't tried anything other than a quick test fitting, but they feel ok. These are the standard Evo blades that come with the new master cylinders, and my guess is that the control blade would be too close, and the power blade pretty much like a standard T4 blade, but I could be very wrong.
The pivot is exactly the same, so no need for any drilling like there is when trying to fit T4 blades to the T3 MC.
From pic, you can see the differences between the T4 (bottom) and Evo (top) cams. The basic shape is roughly the same, but the Evo is different on closer inspection and a bit more involved thanks to the servo thingy.
This shows the T4 blade on top of the Evo blade. Shape is quite different.
These show the Evo blade fitted to the T4 MC, with the adjusters in all the min and max positions
Interesting to see... Looks like the new lever blades have countered my criticism that the T4 lever blades need to be sat so far out in their travel to get a firm feel, so as to only be useful to people with absolutely gargantuan hands. Those of us who prefer running our levers closer to the bar would continually get poor performance due to the lever being unable to compensate for the closer in position. The new blades appear to start much closer to the bar, and be able to go pretty much all the way to the bar for those who like to run their levers super close!
Interesting. Could you update this post when you've tried them please?
Sorry. Haven't tried the combo in anger on a ride, as i fitted the GR4s to the KSL
Questions… has anyone ridden the TV4EVO GR4 with any of the optional levers? Anyone know which lever feels/works most like the TV4 V4?
