    Mechanical discs on Farley?

    Anyone know of a mechanical REAR disc brake that will fit a Farley 9.6? BB7s work fine up front, but experienced local mechanic couldn't fit rear BB7.

    Spykes maybe?

    It looks like the issue is no clearance for the lever that actuates the caliper. Be expecting that issue for any mechanical caliper. Overall size of mechanical calipers is wider to the outside because of this.

    I don't know if this is any use to you, it's a thread discussing the same problem on a Stache:

    The person fitted TRP's in the end, there's some good photos showing the different physical shapes of the two brakes.

    Thanks, looks like I'll try the TRPs. Trek had the same suggestion, but oddly enough didn't know for sure if it would work... I have nothing against the hydros it came with, but they corrode quickly on the beach.

    I measured up spyres i had on a gravel bike and they were narrower than deore hydros i had on my farley 6. Im going to put TRP spykes on my 9.6 with avid speed dial levers soon.

    I had zero issues with my deores for the first winter. I probably should have bled them but the second year they got stiff in the cold and one real cold ride i grabbed fists full of brakes and then i had squeely brakes. Some fluid must have made it past the pistons. TRPs will be fine, I liked the spyres. Center them, tighten the slack, adjust the pad screws till they are perfect and they are awesome. If you put the cable on the inside of the screw it shortens the pull. Also the best part is they fit shimano pads matched with shimano rotors they rocked. I had xt rotors with the spyers and imo worked as well as my sram apex hydros on my tcx.

    Using TRP Spykes on my Farley 9.6. Plenty of clearance. But my axle is all the way forward, which is where mine stays even with clownshoe/4.5 tires. If you want to move the axle back it might be a problem-looks it could go back maybe 3/8". Also, I use 160 rotor- I think a 180 rotor would also work with axle forward but further reduce how much back you could go.

    How are they for power?

    Fine for me though definitely not as good as good hydros. On the steepest downhill stuff my hands sometimes get a little tired, but there's always enough power to do the job.

    Okay, thanks Teton, you settled it as far as I'm concerned. Spykes it is.

    Suppose i could up the rotors too. I did this on my gravel bike in the rear a 140 to a 160 and it was night and day.

    Thanks.

    Well, that's a good question, and I'm considering it. Mine are Avids, but I take your point. I could get another several hundred miles free before paying for new mechanicals. Might do this, even though I'm anxious to put the hydros behind me.

    I'm not a big fan of mechanical brakes, but the Spykes that came on my bike were actually really pretty good. I definitely liked them better than the BB7s that I have on one of my loaner bikes.

    I replaced the Spykes with OEM Formula C1s which can be had really cheap. The reviews on this product tend to be less than stellar, but they've been awesome in my experience.

    I know this is a very old thread and was wondering if you had a picture or could take a couple pictures of the Spyke Caliper on the rear ?

    I would gladly buy you lunch
