Poor after sales service I've never given a bad review for a product before I've had chance to use it, but in the case of these Shimano Ultegra disc brake shifters & calipers, I can't actually install these because the hoses need shortening, which requires 2x brass barbs to be pressed into in the ends of the cut hoses before joining (and they're not included in these oem kits). You'd think Merlin would supply them (because unless you've got an XXL sized bike you'll need them) or at least I'd imagine they would be happy to send me 2 (prob cost pennies)... but no...! Customer service said get a craft knife and cut them out of the hoses... easier said than done John. Lost fingers & corrosive oil everywhere... I won't be doing that... and I won't be buying from Merlin again...
