After asking recently on here I just bought a pair of MT5’s for the same price as SLX from a shop in the NL’s called mantel.
I had to get my lbs to bleed them after shorting the cables myself, its worth noting they are extremely sensitive to bleeding and I can understand people’s comments on not feeling right after, you really do need to get it right.
Anyhow they are designed for two finger braking so the levers are huge and very different to shimano
But I’ve managed to set mine up fine as single finger.
After 6 rides in the biggest thing I notice is how I’ve stopped skidding all over the place as the modulation is miles better.
This also results in less brake drag and pressure on the levers and hence less cramp on longer descents
Planning on upgrading to the smaller single finger HC levers in the summer as I think with these they will be perfect for me.
Overall for the same price as the slx its a no brainer to choose the mt5 (providing they continue to work as well of course)
