    Question building a training road bike

    Carlos: Do you have one of those things that cuts the threads to install bottom brackets on brand new modern road bike frames?

    Here's the situation: I want a cheap road bike to put on a dedicated stationary trainer. I've been looking for someone's old bike to use, but I'm not having any luck. Plus, from what I understand if they are older than about 94, the width between the dropouts is too narrow to use modern parts for 8 and 9-speed drivetrains. Which I see as a problem really only due to maintenance. I don't want a bike that I can't get parts for.

    There is some company or person that keeps selling new aluminum, unpainted raw frames on eBay. Here's the next one I'm interested in. They always go for about $70. I was thinking I could put Tiagra or 105 level drivetrain on it, a cheap handlebar and fork, cheap stem and decent seat and cheap wheelset and I'd be set. I'm thinking if I bide my time on closeouts and watch eBay, I can do it for less than $400 total. Weight is not an issue.

    Thing is, I'd need help installing the cranks and BB, and probably cables for the derailleurs. Sound like anything you'd be interested in? I don't know if you've got any road bike tools like that?

    i don't have the bbb facing an chasing tools.

    that's better done by a shop. did he suggest that be done? ask if it's been done already. you may not need to do it.

    if the shell has no threads, that may be a little trickier since you're going to need a frame jig. and frame builders are usually the only people who have those. not shops.

    the tools are the same for mountain and road and i work on both.

    sure, BB install is quick and easy and so are cables and housing.

    let me know.

    The threads certainly appear to be there. I don't know how important it really is to "chase" them if it's just going to be a cheap bike for training. Although, I'm certainly going to be hammering hard on those pedals occasionally. I'll worry about that later I guess if I actually do it. Here in the photo you can see them pretty clearly.

    OK, thanks and I'll keep you posted.

    Funny you mention that guy Dave, I've been eyeballing alot of his auctions. He either refers to items as "Raleigh or Diamondback" a lot. I know they're the same company now, just finding it odd. Nashbar all so has a road frame. Since the one you linked to is aluminum, I'm going to go out on a limb and say material really doesn't matter In any event, here's the link to that one, Nashbar Aluminum frame on sale

    dave, youmay want to, once you get the frame, manually, without grease, see who well the BB will thread into the frame. if it fits tight then consider a chasing. if it threads in smoothly, you're ok.

    if the frame was made somewhere that wasn't this guys house, then the frame should be well chased.
