    My new project

    Well I pulled the plug and bought a 1996 Mongoose Rockadile today for 20 bucks. I found the sticker on the frame that showed it was sold by a LBS that used to be in our area years ago and who is a current friend of mine. He ran the serials from his computer program and found the original owner and said they bought it and a few accessories for $1089 back in the day. It is a made in Taiwan frame and has bolt on rings and a Shimano crankset as well as an Alivio rear hub and freehub cassette. I noticed the rear wheel was a cheap bolt on wheel and he said I have the original wheel at my apt. So I drove him across town and sure enough there was the original Mavic rear wheel and QR. I didn't realize till I got it home that the front wheel, even though having the original chromed QR, was a cheap wheel. I think a new set of wheels is in order. I will probably re use the rear hub as it is higher quality and maybe try and buy an Alivio front hub to match. One thing I noticed on the underside of the rear stays was the cross tube near the BB is broke out at the bottom but there is absolutely no damage anywhere around it. I swear you would think they welded a piece of aluminum U channel in except the edges are not smooth. They appear jagged and slightly uneven indicating a break. But what in the hell would have broke that out with even so much as scarring the surrounding stuff?

    All in all not bad for a 20 dollar bill huh?

    Sweet deal! It would have been a $100 deal where I'm from.

    Looking forward to seeing the progress.

    Did you find this at a thrift store? I always see nice old bikes at thrift stores.

    That is a nice frame, but it has a 1 inch steer tube. It might be difficult to find a good fork.

    what is this plug you speak of? i'm curious incase i have a plug i can pull too and buy another bike for $20. hmm, maybe you meant trigger?

    anyway, looks pretty good. that broken piece if a tough one. hard to tell from the pics. does the weld overlap where the piece is broken? the only thing i can think is that a kick-stand used to be mounted under there and it look a hit and broke the mount off the frame.

    I like the "complex aluminum array" sticker, they should bring that back.

    so what's the plan? strip the gears, keep the cranks and bars? swap the brakes? probably add a rigid fork? if your building wheels too, this $20 project might have just turned into a $700 resto-mod. don't let it get out of controll... i can build a hell-of-a single speed for $720.
    Rigid SS 29er
    SS 29+
    Fat Lefty
    SS cyclocross
    Full Sus 29er (Yuck)

    Stop asking how much it weighs and just go ride it.

    Trigger yes lol. I never thought about a kickstand. @wjphillips no an individual had this for sale for over a month on the local Facebook swap. I am thinking keep the frame, seat tube, bars, using the 130 mm quill stem from my wife's Bridgestone to lengthen the reach on this bike, the rear hub, brake levers, and build new wheels, replace BB, add spacers and a cog, new brakes, pedals, tires. I got a perfectly good Rennen Rollenlager tensioner. Fork I am unsure of. Since it 26 wheels I am thinking stuff should be dirt cheap.

    Looks more like 1 1/8th to me - surely it would have been anyway in 1996?

    I haven't measured but plenty of 1 inch forks at Niagara cycle. Are quill stems still acceptable for mountain biking or add they too weak?

    Well what can I say. I got bit by the impulse buyers bug and got super excited when I bought an old higher quality bike for such a low price. But after much thought since I have decided to rob a few parts off of this bike and toss the rest. I think the Shimano 5 bolt cranks are worth the 20 bucks I paid. They will still fit on many modern bikes with square taper and they have bolt on rings so they may come in useful in the future. If this bike had come with the original wheels front and rear and a simple chain ring, rear cog, seat, tires and tube was all that was needed I would go for it. But by the time I put in it what it would need to be fun and reliable on the trails I will have several hundred in it if I go cheap on wheels and other stuff. I would rather hold out for something a little newer and nicer down the road and spend a little more and have better components than go cheap with this one to keep it in a budget that makes it worth it. Hey I guess you guys got some cheap quick bike gutter porn out of my post anyways.
