    Bolt on disc bracket for GT

    I have a 2001/2002 GT hardtail that doesn't have the mounts for a rear disc brake. Is it possible to get a bolt on bracket to allow a rear disc to be mounted?

    Ive had the A2Z DM-UNI disc adapter on my Zaskar, and it works perfectly, recommended by me

    Alternatively, if you fancy doing it properly try here first! - https://www.betd.co.uk/product_list.asp?CategoryID=118

    Hi Jobe,

    Do you have any photos of the A2Z disc adapter on your Zaskar that we could see ?
    Do you have to do any drilling to install it .

    I have a Xizang that I'd like to discify and the DM-UNI is on the list. Do you think it would fit ?

    How come you didn't go with the betd disc mounts instead ?

    Weld on a ISO mount! It will be difficult to put on BETD mount with your small dropouts!

    Disc brake adapter

    I have one on my Fiance's Schwinn. It works great. The only problem is when you move the bike backwards, and hit the brake, it'll pivot the caliper upwards away from the disc slightly. Worth the bother having front AND rear discs.

    Thanks, I'm just looking at all options now and am considering a welded disc mount plus the bolt-on options. I've thought the same since it these dropouts are pretty mininal compared to an alloy Zaskar or Avalanche etc.

    Finding a welder that has experience with Ti is another factor. The Paragon mount definitely looks like an option. Thanks alot for this link

    It doesn't look as bad as the V-brake boss mounted disc adapters. Thanks for the shot

    I'll go full disc. I changed my dually frame from a v brake to disc model but it is bit harder this time since they aren't making any more Xizangs.

    Heres a pic of the rear of the A2Z adapter - http://jobysbikes.fotopic.net/p32211563.html

    These sometimes crop up on Ebay for good prices.

    They only work on frames with flat dropouts. The reason i didn't go with the BETD fixed mount was i that i didn't want to start drilling holes in the dropouts of my frame. Glad i didn't bother as this little widget worked really well. If you tighten and space the plates correctly it shouldn't really move at all. I resorted to using the little circular metal adjusters you get on Presta type innertubes as shims!

    The A2Z adaptor suits your Zaskar really well. The beefy dropouts work well with it and it doesn't look like an afterthought. Drilling the rear dropouts can't be a good so lucky you didn't have to do it. Nice work.

    Thanks for the photos. I've always loved the burly welds on the Zaskar too. I think my dropouts might be a bit small for the A2Z widget though. I'll have to try one though to see if it suits. I can get one locally and must have a closer look at it.

    Thanks again Jobe. You have a nice Zaskar there

    Would the A2Z work on my 1997 GT LTS-1? It has flat beefy dropouts.

    laurenlex - i dont see why not, the adapter would fit fine as you dropouts are flat. BETD also make an adapter that screws straight into the dropouts of a few of the newer LTS frames, shown here - http://www.betd.co.uk/product_list.asp?CategoryID=118

    As a side note - The A2Z instructions have always said that the adapters are not suitable for steel frames but as thecraze has shown above, it is possible to make them fit.

    Does anyone actually have one of the A2Z adaptors on their LTS? If so give us a shot and your review.

    I am not familiar with the Scott Octane FX2, but looking it up on Google image search I found this photo: http://hyperinzerce.cz/x-cz/inz/2301...t-octane-2.jpg

    The A2Z DM-UNI adapter needs to sit pretty flat against the top edge of the dropout. And for best performance the dropout top edge should be in-line with the angle of the chainstay. On the bike in the photo I have referenced it appears the dropout is at a different angle than the chainstay, and the tubing of the chainstay bulges at the end, not making a smooth transition between chainstay and dropout.

    Check the photos in my review of the adaptor: Keeping a weather eye on the horizon: Equipment Review: A2Z DM-UNI Disc Brake Adaptor

    You can see the LTS dropout lines up pretty well with the angle of the seatstay. Even though there is a tiny bulge at the weld, it is not enough to throw things off too much. I have ridden with this thing for a while now and it has stayed tight and square, no movement of the caliper at all.

    If you can get a solid clamp on the frame, meaning the dropout area is big enough for the adapter to "sandwich" with, then it should clamp strong enough. The Scott dropout looks like it might be large enough in this respect. I just am not sure about the angle you will get on the adapter due to the angle of the top edge of the dropout, and that bulge on the seatstay/dropout junction.

    Quality review an thanks for the time taken to reply! I'm not sure about the amount for dropout space so to put it , so the a2z will be able to clamp. I might just purchase it to see. Silly question maybe butt will the a2z come with fixings?
