Anyone know anything about disc brakes?

  • Ok, hydro >>>

  • <<< hydro

  • These are rad. I was sent an SLC caliper in error; the actuation arm is crabon, hardware titanium and the body polished alu. Sexh, no static pad, light as, no fluid to muck about with:

    Takes shimano pads. What's not to like?

    There's a good flame war discussion on the pros / cons between cable and hydraulic on Soul's commuter thread. Starts here.

    Yes, there is :-/

  • Those Spyres look nice. BB7s work well, but they are a bit clunky looking.

  • With the speed dial leavers I hear they are the nuts. Tempted to put them on the Stanton. There's a Spyre MTB in the works, too apparently.

  • ^^^^
    They're very much based on the dual bangers. Which were meant to be the answer to cable disc woes. By actyating both pads. The reviews where rpretty mixed to say the least, and they died off.

    I think the idea is spot on, and that Interloc merely 'drop the ball'.

    So I'm pretty interested to hear how these are.

  • They 'look' much lighter than the BB7s - any weight comparisons?

    I may eventually build a bike that weighs less than me.

    Goes into another Ti daydream

    I have some bargin basement tektro cable discs on the cargo bike. They are fecking chunky, and fecking heavy. But I run them with Speed dial levers and get great braking. With cables its all about getting the bite just right. You dont want to have to bend the rotor to the stationary pad too much. Yet you dont want to be too close.

    Interesting. Where did you hear that?

    From what I've read their commonality is that they don't have a static pad and are pulled by a cable. The actuation mechanism is supposedly very different.

    They are circa 30g lighter than BB7s IIRC. But then BB7s are porky.

  • Damn - I thought I had finished buying stuff for my long distance bike - might have to get some of these babies now I have seen them. presently running BB7 with Shimano discs on custom Royce hubs.

  • I was wondering who made your hubs. Dayum, etc.

  • This thread reminds me that I need to get my BR-75's swapped.

  • I've got Hayes CX5s on my commuter / kid carrier. Can't fault them. They were dead easy to set up, and after that have required nothing apart from a cable tightening after the initial stretch. Fit and forget really. Powerful and predicible. Dunno about needing them on a road bike though.

    Sorry. Bad wording on my part. Really should have my lawyer proof read this stuff.

    The idea of imitating hydros by moving both pads comes from them. But the mechianism is as you say different.

    Are the pads actuated independantly like a hydro?

    Not that TRP arent idea steeling bastards. I have a set of their 'innovative' rim brakes on my BMC.

  • BB7 only has one moving pad. You can adjust both but only the outer one moves while the inner is static.

    I am going disc soon on my polo bike and will run TRP Spyre, seems much more well made than the BB7, no plastic bits that will fall off or come loose (the adjuster on the outside). Problem is both fatbirds and upgradebikes are currently out of stock. Fatbirds have them on preorder and they said it will arrive by the end of the month.

  • I thought BB5 had one moving pad, and BB7 had 2?

    can't really remember... don't pay close enough attention.

  • TM you have just caused me to identify myself as a TOOL.

    Went to look at the BB7 on my Enigma because I know that they are single moving pad - guess what? They are Shimano road calipers!

  • BB5 has one adjustable pad, BB7 has two but the actuation arm on both only moves one pad.

    You can dial in the static pad (the inner one) on both as your pads wear out. For the moving pad, you would have to adjust the cable for the BB5 to dial it in while on the BB7 you could give the little red adjuster a few turns without playing with the cables.

    Ha!

    Right you are Ben sorry, that was it, both pads are adjustable.

    The whole shizbang with the Spyrs is that both pads move. Dual bangers aside. Cable calipers move one pad to the rotor, which then gets pressed against the second pad. Which is a bit shit. With hydraulics both pads move, and better yet move independantly.

    Cable calipers can be set up to work really nicely. But you need highly adjustable levers (speed dials as mentioned are aces), or loads of patience. You cant adjust bite point or pull ration on road levers. So it can up hill battle.

  • Yup, dual actuation for better braking and reduced squealing.

    +1 for adjustable levers. I went for Shimano DX: http://www.chainreactioncycles.com/shima­no-dx-brake-lever/rp-prod106267

    Them HY/RD are helluva tempting but at 110 a pop it is currently out of my budget, might just splurge in Christmas as a present to myself.

    I found the Hayes cable disks have all the adjustment you need at the caliper. Took less than 10 mins... When installing them set the cable length so the pads sit quite close to the rotor. The inner pad is static and adjusted in/out with a 5mm alen key, finally cable tension can be fine tuned with a barrel adjuster on the caliper.

  • Any idea how many people are riding discs at the top level now?
