    IS disk brake on DW 5 Spot?

    Just found out that the DW 5 Spot frame has a postmount disk brake mount. Will I be able to fit an IS brake by using an adapter?

    you will be able to run a 7" or 180mm rotor with an adapter, but if you really want to run a 6" or 160mm rotor you will need to join the new world order and get a post mount caliper for whatever brake system you run. Sorry!

    Ok, I can live with an 180mm rotor. The budget doesn't allow for new brakes as I already have Hope MonoM4's that are perfectly ok. Do I use the same PM->IS adapter as a front brake PM->IS adapter?

    The majority if not all Post to IS adaptors will have been designed for forks, which presents problem. IS mount calipers are different front to rear.

    I faced the same problem moving to a DW Spot. I had a 180mm Hope M4 Mono on the rear of my old Spot. I used the Hope adapter and a 20mm bigger rotor. It just about works, but the caliper only covers about two thirds of the rotor. It's not a major issue, it still stops and the rear brake isn't loaded anything like as much as the front.

    I'm only using it because I have a new pair of Formula brakes on order, and in the UK at least they are taking about 3 months to turn up.

    I used this one, purchased from CRC http://www.chainreactioncycles.com/M...?ModelID=13735

    Ebay

    I just found older XTR post mount calipers on Ebay so a local friend could upgrade her Nitrous to a new Flux, and she needed one for the front as the older Fox was IS as well.
    Posts are out there and bolt right on.

    Hey Andy. For Avid, use the front post-mount 185mm adapter.

    Another option.......

    I'm going to have the same problem at some point.... so here's another option.

    Purchase a new MonoM4 post mount caliper = $125 (You might also need a new rotor - I don't if they up'd the rotor size with the new style calipers). Then sell the old caliper (and rotor) on ebay..... which have been going for about $80 used for a MonoM4 caliper.

    If I get a DW Spot.... this will be my plan.

    When I changed from an IS fork to a post mount fork, I replaced the front Hope Mini two piece with a Hope Mini Mono up front but continue to use my old Hope lever.

    Cheap way - just get an adapter IS to Post. Hope has a facility in TX. Just call them directly and they'll make sure you get the right adapter.

    Wanna save a few more pennies? Go to UniversalCycles.com. They have everything! But you gotta know what you're looking for.
