Bike polo mechanics & fixing

Anyone tried these yet?

Low profile, both pads are actuated (a first for mechanical disc brakes I think). Pricey though.

Not yet but have them on order and will get them on the bike once I get the forks sorted. Not too pricey considering a pair of BB7 is abut 55 posted and these are 64 posted.

Very tempted to try the HY/RD one as per below! Now that's PRICEY!

This is a bit of uncharted waters but I am going to give the TRP Spyre Disc a try. It is more compact than the BB7, less fiddly and generally looks better made. Lots of good reviews at the bottom of the page but alas nothing in relation to polo of course. They are short pull which means that paired with a conventional v brake lever will give you a sharper stop but I will counter that with a adjustable lever (I chose the DX, the Avid SD is another option) to enable me to choose my preferred settings. Nice price too at 64 quid for front and rear.

There is also another TRP disc that I am keeping an eye on, the HY/RD which at 100 quid for front or rear isn't really cheap. The reservoir is at the caliper (gulps...) and there is no hose but instead it is actuated by a cable (yay!). Quite a few nifty features too like self centering pads and a lock-out option when you are adjusting them. Again untested for polo but I would love to give one a try when I have the cash.
