    2000 Trek 6000 - Possible to convert to disc?

    Is there any way to convert my old (but faithful) Trek 6000 to discs? Obviously the front is a no-brainer by adding a IS adapter to the 74mm post mounts, but I can't seem to find any mounts on the rear for discs.

    Is there a way to deal with this?

    There may be a way...

    but it's going to be a pain in the butt. If the bike has a mount in the rear it will look like the photo below. If you do have such a mount it is a 22mm direct mount. In other words it requires an obsolete Hayes 22mm direct mount caliper. The below pic is of the non-driveside chain stay of a 2000 Trek 7000. You may or may not have the mount on your 6000. Not all Trek bikes from 00 had them. The bike was manufactured before disc brakes became so popular. Now just about any bike you see has disc tabs in the rear and they are either IS or Post mount so no problems.

    Anyway, if your bike has the mount you'll need to find a 22mm direct mount Hayes caliper. Not an easy task anymore as they are becoming quite rare. You can contact Hayes and see if they have any, or you can shop around on Ebay and see what you can find. The only other option is an adapter that is made that may or may not work for you. The adpater bolts to the frame mount and the caliper mounts to the adapter and allows the use of a modern brake caliper. But it depends very heavily on the size of the frame and the caliper that you are using whether or not it will work. Frames smaller than a large (19.5) and/or larger calipers (this is dependant on the brake manufacturer) won't work because of clearance issues between the stays.

    Unfortunately Trek used this design from about 98 or 99 until around 01. From there they went ot a different adapter configuration (still no IS tabs built into the frame) that bolted to the chain stay and allowed the use of regular (by that time) IS mount calipers.

    So if you have the mount on the frame, your best option is to try and track down a Hayes 22mm caliper.

    I definitely do NOT have that mounting tab on my frame. I guess I'll wait until I buy a new mountain bike before I worry about disc brakes.

    Yeah I couldn't remember if the 6000 had the mount or not. Like I said not every bike in the Trek line had a mount in 00. Now days everything but the lowly 820 has disc tabs on it.

    But all is not lost. There are a couple of adapters out there that allow the use of disc brakes without mounts. Brake Therapy makes one, http://2btherapy.com/index.php/bikes...conversion-kit , they're kinda spendy and they add additonal weight to the bike over and above you disc brakes. Just depends on how badly you want discs on your old 6000. Not the ideal solution, but cheaper than a new bike and they work.

    Your choice on that one.

    another option is to just run a disc up front. a "mullet" if you will. A2Z adapters is another potential option.

    Yeah.. I'm thinking of just switching out the front to disc and leaving the rear as is. I need to get a new front shock first though.. my stock shock can't handle my clyde ass!

    Actually you can put rear disc brakes on this frame. I did it on my 01 Trek 6500 with no problems. You would need this bracket to do it.

    It does add a little bit of weight but if you really want to go w/disc this will work.

    That is not my bike by the way. Mine looked much better as i used black not red.
    The only other option is to find the original Hayes brakes that Trek offered on these frames.
    They are not too cheap if you are even lucky enough to find them. The bracket is much easier and cheap at only $22. Either way good luck!
    You can find them here http://www.torontocycles.com/images/P1010005_2_.JPGas well as e-bay.

    Uhm, yeh he does. Look at the pic of his bike. It is a Hayes 22mm mount which is the same as my Trek and what is listed in my post.

    This adapter converts parallel (22mm chainstay)
    mounts found on Trek, Klein, Schwinn and Jamis
    bikes, etc. to Post Mount Calipers.
    NOTE: This adapter gets around the common problem
    of the caliper hitting the seat stay tube.

    Or you could always go with the original brake design from Hayes. I just found one on ebay...
    http://cgi.ebay.com/Hayes-brakes-22m...ht_1386wt_1167
    ...and with a Buy It Now price of $89 for both F&R, its a steal! Usually when you do find them they are over $120 for a set.

    Unless I'm blind, but I do not see a pic of his bike, just a pic Squash posted.

    A lot of us have run a disc up front and Vs on the back on our upgraded old bikes. It works fine. Put a nice new set of Kool Stop pads on it and you'll never notice you don't have a disc on back (well unless things get really wet and sloppy). If you've got a low quality v-brake, think of upgrading it to a single digit 7 (or 5). Pricepoint usually has last year's models pretty cheap. If you run a Disc/V combo, you're generally better off running a mechanical Disc (preferably a BB7) so the levers feel similar.

    Yeh, youre right about the pic. I am pretty sure that this is the mount he has as I had a 2001 Trek 6500. SAME! When Disc brakes were making the scene back then this was pretty much the standard mount. 22mm. Trek didnt do anything different from 2000 - 2001 on simular models. Ask dcronkhite to post a pic and you will see. If is different than the 22mm and it is not IS I would like to see what eles it could be.

    Kminca the OP already said he does not have the 22mm mount. Did you not read response number 4?

    Yeah that was a pic of my 00 7000. The 00 6000 didn't have mounts for disc brakes. Back then only selected bikes in most manufacturers lines had disc mounts. Not like today where just about everything from high end carbon bikes down to Wally World clunkers have tabs.
