    Risers and brake options

    I want to try a set of risers on my road conversion, and I have a few questions regarding bars, as well as a few brake questions related to said bars.

    As for the bars, Is something like this Nashbar Cross Country Riser Bar a reasonable start? If so, the diameter isn't listed for these bars, and I also don't have my bike around to measure my current bar diameter, but they are standard late 80's/early 90's road drops of some sort. From my reading on sheldon's site, I'm hoping all will be 1", but if not, please someone let me know!

    Next step is to add a brake. I have a caliper from its road bike days, but I know that the stock lever won't work. So the first question is, what diameter brake lever do I need to fit standard risers. The next question is on the pull options. I know there are many different types of levers and calipers, and the compatibility is unclear to me. If someone wants to explain some of the typical conventions, I'd appreciate it greatly.

    I suppose in the end if someone wants to just say:

    "Here, this bar (insert link) and this brake lever (insert link) will work for you and are cheap. Give them a try."

    That would be fine. Although I'd much rather understand all that is going on.

    Thanks in advance,
    James

    hey bro.

    i would go to your local LBS and check to see if they have a bars bin, that's where i got my first ones.. and there, you can cut them to size too.

    these easton monkey bars
    are a good bars. they come in carbon as well. but, i got my bars bin ones for 15, and they worked good. the size on these are 25.4, which is pretty common.

    the lever, you can just get a bmx or cross lever. something like this would work.

    as far as i know, unless it is stated specifically that a bar is oversized, if it is a mtb bar like risers, the clamp diameter should be 25.4.

    as for a brake lever, either a bmx lever or mtb lever should do the trick. it's all about bar diameter... road bars are 15/16, while mtb bars are 7/8, so you can often fit bmx and mtb cross levers on road bars, but not vice versa...

    someone feel free to correct anything here that i am mistaken on.

    Just about any riser bar and a BMX lever will work, and work great. If not a BMX lever, a CX lever will work too.

    I went the parts bin route, spent less than 15 bucks for no name riser and right side BMX lever. The right side brake works great when cops are in sight. If I need to use the e-brake, can still use the hand signs for stoping.

    Wow!

    First, thanks everyone for the helpful and well articulated answers!

    As for brakes, let me see if I can summarize my assumptions. There are two basic pull types for levers, short ( for bmx/cx type apps.) and long (for road drop type apps with more clearance behind handle). The actual amount of cable pulled is the same for either, but the lever movement differs.

    Is caliper functionality independent of the lever? I know there are many different caliper types, but are those more related to the frame/fork, and the intended use?

    You guys rule. Off to adams avenue after work!

    One can use "v-brake" levers on caliper brakes, just not the other way around.

    Edit:Modulation will be slightly different than using a lever designed for a caliper style brake.

    backwards the pull refers to how much cable they pull

    short for calipers, cantis and a small number of specially designed linear pulls and discs

    long for the vast majority of linear pulls and discs.

    Some adjustable pulls(designed mainly for long pull applications) can be adjusted down close to short pull.

    you can if you have to use a long pull lever with a short pull brake but leverage will suffer.
    Problem solvers makes a pulley for using long pull brakes with short pull levers... maybe you could rig it backwards.

    The only other issue you might run into is what kind of stem you have. If you have a closed face 1" stem the 25.4" bar is going to require a shim, Nitto makes a shim that is around 12$ or you can make a shim out of various materials i.e. "beer can shim". Do a search there are tons of threads on this. I'm a ***** so I bought a Nitto shim but I understand it's easy to make one.

    This is very helpful, although only if you know what type of brake (caliper, canti, linear, etc.) corresponds to what application (80's road, current road, mtb, etc.). Since I don't know that, I can't make much of what you're saying here. I know the content is solid, it just isn't helpful for me. Yet.

    Any thoughts?

    I got practically new Haro risers for like $6 at my friends shop. Love em.

    And for a brake lever, I'd recommend a folding clamp style so you can take it off/switch it to other bars without removing your grips.

    Take it in and they'll fit it to your rig.

    most things that aren't current mtb(post v-brake revolution) are short pull. I think diacompe makes a long pull road lever and there are probably a coupe of long pull bmxes but I don't know.
