    Just a FYI, the 26" is the diameter of the tire, not the rim. Same with a 29er, 29" diameter tires, not the rims.

    True. Thanks to specify. I didn't want to confuse new users with ERTO measures and more technical standard. I guess you could always post a link to Sheldon Brown's website page on wheels sizes and standards :)

    Ya I knew what you were saying. That's why I didn't say you were wrong, just a FYI. Usually I get the :confused: look when I tell people its refering to tire diameter and not RIM diameter. It doesn't really make sense to me to go by tire size rather than rim size when the tire diameter changes depending on which tires you use. I think a fat bike tire 26x4.x is actually around 29" in diameter but still considered a 26" And I think every other type of wheel (motorcycle, car, etc) goes by rim size. But when buying rims they are usually sorted by 26" and 29" which doesn't help to the confusion.

    Yeah, that's right. Me too at first I was like, the rim is 26" high and the tire is 26" too. Then I took a measuring tape and I ended up in a white room with padding and no furniture.

    But seriously, this can be very confusing, but since any 26" tire fit on any 26" wheel, I guess it's more of common sense and people just don't even care about it. Unless you're trying to build/make something that is in direct relation with rim/tire dimensions (like a truing stand for example).

    Still waiting for the link.

    ^^ Agreed with above. The quick facts will be referred to again. I've been out of the bike scene for about 10 years, so all the technology and standards have changed since then. Much to my chagrin when I recently tried to revitalize my 15-year-old hardtail with components off a newer bike... :madman:

    Could anyone elaborate on the difference between AM, XC and FR please? I think FR is mostly for trails with jumps, something close to BMX almost?? But was is difference between AM and XC? Arent they the same trails?

    I think this has been done already... but lets see what I can do.

    There are various definitions for XC, AM and FR.

    XC
    1) An internationally recognized sport where you race against a few dozen others on the same trail
    2) Just riding trails. Distance and Speed probably matter to you.

    AM
    Just riding trails. You look for challenging trail features, Speed and distance are there but only matter in terms of trail experience. You want a bike that can handle the trail features at the speed you want.

    FR
    Lots of variety but jumps, drops, elevated features and other "stunts" tend to be featured. You don't ride for distance: it is all about the "stunts" and the bike has to be able to survive them - and not hinder the stunts.

    Last week I rode with a pretty mixed bunch. At one point, us more wheels-on-the-ground riders took the reroute around a fallen tree. The two guys who are into "Enduro" (an AM like race format) picked up speed and hopped over that tree that is too high off the ground for me to even consider.

    Thanks for response. I've been looking into this question and your answer is what I got as well. I also noticed that bike sizes differ between the disciplines. It seems that AM/FR generally have shorter top bar lengths whereas the XC folks like a more traditional longer top bar length. FR/DH also like to keep their seatpost lengths low to position their bodies around the angles.

    one day i'll know what Fixie means

    In XC bikes, people favor pedaling efficiency, and to some degree even aerodynamics. A longer top tube can help with those things.

    For AM/FR/DH, people want a bike length that lets them apply a lot of body language for maneuvering the bike. A somewhat shorter bike can help with that.

    Difference between FR and DH: in FR you live for the stunts, in DH you mainly care about going fast. If you are racing DH, you ONLY care about making it from start to finish in the shortest possible time.

    Fixie: if your cranks are turning, the rear wheel is turning too. If your rear wheel is turning, your cranks are turning too.
    Mind your fingers when cleaning and lubing the chain: you wouldn't be the first one to get your fingers mangled after forgetting the rear wheel works like a flywheel and the chain keeps moving with it :eekster:

    Definition Single Track
    Looking at a single track bike on CL, waiting to hear from owner. What is a single track? If that means 1 sprocket fr and rr, can I add more sprockets?

    Single track usually refer as a tight biking trail that only allow for 1 bike wide and goes along in the forest/mountains.

    Single speed bikes are usually regular bikes with only a single cog and spacers or a freewheel. Depending on the drop-out, you may or may not use a derailleur, which means you might not be able to run multiple gears.

    Awesome, very good glossary. TY so much and GBU (God bless You).
    maybe add: (bcoz I dont see these on the list)

    Granny - refer to small chainring.
    Bashguard -- usually replacing big chainring to protect the drivetrain.
    Shim -- not sure how to describe it though, need help on this.
    missinglink/ master link -- a chain link that can be detach without tool. (maybe someone has better wording?)
    Dropper post --- adjustable seatpost, could be mechanical like Gravity Dropper or Hydrolic like Reverb.
    WTF -- (when you are about to fall).
  • 12-06-2012

    a bit more:
    HAB --- hike a bike, when you r out of gas, you push your bike up.
    Sandbagger --- a rider who said he is a beginner, but actually rips.
    Speedy Gonzales --- my bike's name...hehehe..
