    Hi! I'm new to bicycling, having had some old beaters in college that got me to campus and back...

    Recently, I bought a used hybrid Trek off of Craigslist for $75. It shifts fairly well and looks good, but I have a couple of questions:

    1) The bike frame states it is a "820 Aluminum", with no suspension and Shimano parts. I haven't been able to find any other info on this bike as everytime I look up a "trek 820" on Yahoo or Google, I get a bike that looks nothing like mine. Any ideas where I can find more info and/or a manual on this bike?

    2) After I took my "new" biek home and had a much better look at it, I discovered that the left crank arm is split where it attached to the crank. It hasn't come apart yet, but I fear it will soon. The model is a Shimano Altus FC-CT93. I am having much difficulty finding a replacement arm online (even at Shimano.com) as this appears to be an older part. I don't want to replace the whole crankset ass the rest of it works great! Any ideas where I can find a replacement arm, or fix the old one? EBay hasn't been much help, either.

    Thanks for helping out a newbie!

    Have you already looked for your bike in the catalogs on the Vintage Trek site?

    As for the crank arm, yeah...sounds scary and should be replaced fast. I'm guessing the crank arm is aluminum, so fixing it doesn't seem possible or economical to me. Your bottom bracket is almost surely an old-school square spindle type, so you've got options, if you don't mind the arms not matching. Any bike shops nearby with used parts bins? I guess you should take care to choose an arm that puts your pedals at the same distance from the center of the bike or, minimally, that clears your chainstays.

    Thanks for the advice! I took it to a local bike shop, who looked for a spare arm... then noticed the sticker for the shop the bike was bought at and suggested I take the bike there (even thoughh I bought it used). I took it across town to the bike shop (Penn Cycle); one guy came out to look at it and said, "Warranty!" At one time I had 4 people looking at my busted crank arm shaking their heads... long story short, they're calling Trek for a replacement arm. Hopefully this will turn out well!

    This don't happen very often. In my experience, once an item is sold as used, the warranty expires. This is the norm for a lot of industries. Only more expensive items such as automobiles have transferable warranties. Some companies will allow a warranty to be transferred but at a cost.

    That may be true, but only if I told them I bought the bike used... which I didn't. 😄

    I believe the FC-CT93 is on the list of recalled shimano cranks. Most of the old Altus cranks are on the list. Take it to the local shop and have them check it, if it is on the recall list then it should be replaced at absolutely no charge to you.

    EDIT-looked it up. It's the FC-CT90 that was recalled, not the 93. You just need to go get yourself a new crank arm.
