    SS - bullseye hub

    I have a early 90's threaded bullseye hub. If the rim was laced centered(Like a front wheel), do you think it would work?

    I guess back then they didn't make specific MTbike hubs because they used a bunch of washers to make up for the wider dropouts so I have some room to work with.

    you mean the hub is threaded to accept a freewheel?

    so long as the distance from lock nut to lock nut is 135mm, it'll fit on a mountain frame.

    depending on your weight, you might be able to use a nice, light, non ASYM rim. this would prevent a weight penalty. if this is the case.

    also, try to get a rim that is identical to the current one. enough of a change in rim dimensions from one rim to the other, and you might end up having to center the pads every time you change from a geared wheels to the SS wheel.

    of course, if this is going on a bike that you plan on using for SS only, then it's not an issue.

    Threaded for freewheel.

    The axle is 135mm. I just think it was there BMX hub made to fit a mtbike with the use of spacers.

    Once I convert it, it will stay a SS. Klein rascal with horizontal dropouts.

    My main question is whether to lace it asymetrical or symetrical.

    Wumpus posted "Klein rascal with horizontal dropouts."

    wow! what color?

    "My main question is whether to lace it asymetrical or symetrical."

    i'd say lace it to a symetrical rim of the flanges are spaced symetrically (in relation to the axle) when the hub is mounted to the frame.

    and lace it to an asymetrical rim if the flanges are spaced asymetrically when the hub is mounted to the frame.

    ay any rate....choose a nice wide rim......maybe a Sun/Ringle Singletrack or a CR18?

    It is dark blue when looked at from the front and a light blue looked at from the rear.

    So, if I can get the hub centered in the frame, lace it symetrical?

    Sun/Ringle Singletrack or a CR18 -- Do these both come in the offset asymetrical -- Don't know the actual term for when the eyelets are corrected for the dish.

    Okay I'm waking up

    Put the hub in the frame and then measure the distance between the dropout and flange from both sides, right? Does it have to be perfectly centered or can I get by with a couple of mm either way .

    when a rim has eyelets that are offcenter, it's called an asymetrical or offset rim.

    it's not the wheel that asymetrical....just the rim.

    and really....all an asymetrical rim does is aide in evening the spoke tension from hub flanges that have been shifter to the NDS by the addition of more and more cogs.

    i've built rear wheels and disk wheels with both types of rims and they hold up just as well.

    but in some cases, it's needed. on CODA hubs, and asym rim, is a nice rim to have. it sucks when you get the DS to tension and the NDS is slightly below ideal. and it sucks even more when you consider that there are going to be disc brakeing forces applied to the side with low spoke tension.

    sometimes, cranking up the DS will yeild decent results. but you might end up with an unstable wheel because the tension on the DS is so high.

    Sun-Ringle does not make and offset rim. they are one of a few companies that stand by the premise that asym offers no advantage.

    yeah....a few mm each way is ok....make 5 mm your limit. this will allow you to use the same length of spoke and further simplify the build.
