Look into TRP Spykes. Leaps and bounds above the BB7s. You can probably find them for around $50 (per caliper). Then you'll need a lever. Avid Speed Dial 7s are great. Or if you have older V-brake ratio levers on hand, you could run TRP Spyres.
I'd still rather spend £6 on a disk and undo & do up 6 screws, that £30 on a rim, £3 on a tape, £25 on a set of spokes and 3 or 4 hours re-lacing.Lebowski wrote: ↑Dec 14, 2017 7:56 amI agree with Chalo about rim brakes... I mean disc brakes are getting larger and larger diameter, only a few more years till the disks are as large as the rims.... at which point everyone will realise rim brakes are basically disc brakes with the biggest disk possible.
This one is a models with a lager brake and it has a @ 140mm cooling disc its no slouch in the cooling department. Its in the same family as the 80 and 81 they share the same instruction set.

The Avid Speed Dial 7 levers are adjustable, not sure on the ratio range but I know they can be successfully used with v-brakes too. I know nothing about roller brakes and what they require.eCue wrote: ↑Dec 14, 2017 10:48 amThe plot thickens
Was going to use mechanical xtr levers until i bought the Roller brake they need a different pull lever so i need to upgrade / downgrade the levers to RB compatible. Pee me off as the money adds ups fast. Now I need levers ( they have a switch for v-brake or RB ) and a mech disc brake. With such a strong review in the TRP's favor I will try to find a TRP caliper within my price range
I meant canti instead of v-brake there. Looks like you got it all figured out though.
Really? I found the opposite. Since the both pads pull, you would never have to adjust the inner (stationary) pad in.
Carbon rotors are available and have been used on downhill mountain bikes. The rotors don't keep enough heat in them to be "grippy", so organic pads are used, but they wear quickly.liveforphysics wrote: ↑Dec 15, 2017 11:50 pmBrakes on F1 cars use carbon-ceramic rotor materials to glow at 1200degC to transfer heat. With all the exotic materials and tech people put into bikes, I'm amazed high-end road bikes aren't already running tiny floating carbon-ceramic rotors that weigh just a few grams and glow braking from big descents.
After I figured it out thought you may of meant the first series as they were canti'sEpyon wrote: ↑Dec 16, 2017 9:51 pmI meant canti instead of v-brake there. Looks like you got it all figured out though.
