  1. I am converting a 1995 vintage Specialized Hardrock to singlespeed but
    am looking for some advice about the dropout.

    The dropout is (very) short, less than a half inch and nearly
    horizontal. It has a second hole drilled rearwards of it with a small
    area of metal between the hole and the dropout.

    You can see a photo here http://www.themeades.plus.com/dropout.jpg (57
    Kb, 600x530 pixels).

    What I want to know is; is it safe to remove that area of metal to
    extend the length of the dropout so that I can get some more
    adjustment to tension the chain.

    If it isn't safe what is the purpose of the hole?

    Thanks in advance for any help.

  2. I have a similar specialized, a hardrock frame of unknown vintage that
    I rescued from the trash heap to serve as my single speed frame.
    It is a 130mmm rear that I have jammed a 135mm xt hub into. It also has
    a similar dropout as your frame. I just fit my wheel in the space
    provided and try to tighten the quick release as hard as I can. I had
    to adjust the bearings a bit so they wouldn't bind when I clamp the
    quick release but so far it hasn't been a problem. I have thought about
    grinding off the metal so the wheel can go further into the dropout but
    haven't.
    The wheel doesn't seem to shift when I stand or pedal hard but I live
    in a flat town (manhattan) so I am getting away with a 34x16 gear.
    Good luck,
    Ray

    Jeez, what a low gear for an urban singlespeed! That's more appropriate
    for mountain trails--doesn't it drive you crazy on the flats?

  4. Do people generally use mountain bikes or road bikes for single speed
    bikes? I was going to try and use my old Fuji Supreme steel frame since
    I mostly ride a road bike, on pavement.

    IMO, seeing as how you are riding on roads, the best thing would be a
    road bike. I know that sounds like a radical idea....

    The concept that a mountain bike is the standard is a new idea, and the
    product more of marketing than reality. Mountain bikes were developed for
    riding in extreme conditions, on trails. That is what they do best. On
    roads, they have excess weight, poor rolling resistance due to the tires,
    and force the rider into a posture that will be uncomfortable on a longer
    ride. Suspensions are worse than useless on the road.

    That tape measure is interesting, because I almost had to buy a tape measure
    unit from the UK. You guys are the only ones in the world with both metric
    and imperial units on the same tape measure. I had to buy mine on eBay.

    Those metric+imperial tapes are quite common here. I always wondered
    what was their purpose: imperial units are *never* used here
    (Switzerland). I understood when I started reading r.b.t. :-)

    Thanks. What I didn't like about the Fuji (first road bike) was the
    friction shifters. Otherwise it was a pretty comfortable bike to ride.
    I didn't know at first if I could adjust to riding on the drop bars
    (no big deal now). It had always been kept inside it appears, so it is
    not rusty and seems to otherwise been in good shape. I hardly ride my
    mountain bike anymore unless I don't know what the road is going to be
    like. I will probably get rid of it and keep the single speed and good
    road bike if it works out.

    Well, more accurately, I should have rephrased it as, "I had to buy mine
    online." Metric/SAE combo tape measures were nowhere to be found in local
    stores.

    Dear Phil,

    This list of some other metric/sae tapes includes the
    pricier but usually available Stanley Powerlock II:

    http://search.hardwarestore.com/exec/?query=Metric+Tape+Measure

    Your local stores may not have them, but sometimes the
    trouble is that the employees don't know everything that's
    for sale in the store.

    ("I didn't know we carried that. What is it?"😉

    To be fair, they have thousands of items to try to remember,
    and metric/sae tape measures aren't exactly flying out the
    door.

    Here in Australia you can't (well, you probably can but you know what I
    mean) buy a tape or ruler that is _not_ Metric/SAE combo...

    I run 34x16 on my singlespeed MTB, and it's a bit low on the flat
    trails but I like to spin 100rpm+ just for fun. On the steep stuff,
    32x18 is more rideable and I just accept that I'll be freewheeling on
    the downs.

    Calling it SAE is just typical American cultural imperialism. Feet and

    Dear Kinky,

    Using sae and metric as search terms does help if you want
    to search for such tape measures to help Phil in the U.S.

    I'm looking at a brand-new $1.49 Harbor Freight Cen-Tech
    #38936 tape measure that says "12 ft. SAE & Metric" on the
    packaging. (The 16-foot #38937 model is a foul lie that
    costs $1.99, with no metric markings despite its claims.)

    It's made in India.
