Nice bike there @Crackle! Just a side note though, I have the TRP Spyre on the front of my Felt, it brakes well enough, I did have to clean all the pads and rotors though and re-bed them in to get them working well, as stock they were a bit weak. I can well imagine that @I like Skol's experience is typical as regards the pads. That being said, with the rotors properly adjusted, I get pleeeeeenty of stopping power (more than enough to lift the back end quite a way off the ground - that with my fat arse on it). Although that being said, I am thinking about moving to hydraulics at some point as I'd like to put 105 on the bike this year.
