    Your bikes....?

    Just to change things up a bit, how about some pics of the personal bikes that builders who grace this forum, use.
    We never really get to see them.
    Here's my UBI bike. #2 will get built at some point. I'm too busy blowing holes in tubes...

    EDIT: (this is Walt)

    I've made this thread a sticky, because it's kind of a cool one, IMO. Please only post bikes that YOU BUILT. If you have a sweet custom/handmade bike that you've purchased, that's great, but it's not the point of the thread. Post up stuff that you made with your own two hands. Enjoy!!

    My 2 main bikes...

    I'm not publishing a picture of my townie. It's too embarrassing. Let's just say if someone stole it, I would walk home perfectly happy...

    I ride my singlespeed 29er most of the time. Here it is. Mmm. Dirty.

    Sometimes in the summer I ride my 7" travel bike at the resorts, and sometimes I even pedal it up the hills. It's also a 29er, which is pretty stupid, really. But it was fun to build, and it's fun to ride, and I'm not a DH racer, so the mediocre tires don't bother me.

    At the risk of hi-jacking my own thread (can you hi-jack your own thread?),
    What do you feel are the benefits of using steel for a front end on a FS bike?
    I don't see it, but maybe there's something I didn't think of.
    Is it because you can offer up the "custom" front end?
    Thanks

    Reverse the question, what do you think are the benefits of not using a steel front end, or rear end for that matter, on a FS bike?

    38 pounds, all steel:

    Hey, my thread...I ask the questions here....
    I'm no pro, but my thought process is that steel has an inherent "flex" to it (comfort, if you will, the reason it rides so well).
    I would think that the "flex" would cause binding in the pivot area.
    To eliminate that, you would use a "beefier" tube, causing a heavier weight.
    Hence, that's why aluminum is used.
    Am I way off base here?

    Yes, way off base. Steel is ~stiffer~ than aluminum.

    Start here: http://www.anvilbikes.com/?news_ID=11&catID=3
    Then here: http://www.anvilbikes.com/?news_ID=16&catID=3

    Aluminum is easier to manipulate and machine than steel. That makes it more economically feasible on many designs and makes designing the marriage between light weight and strength much easier. Optimizing a steel frame to compete weight wise with aluminum is tough and the manufacturability difficulties are hard (sometimes impossible) to overcome.

    Why I like steel...

    Todd -

    Just FYI, that DH bike is all custom. Not just the front end. And it's all steel.

    Why?

    A) If something cracks or dents, I can easily fix it without resorting to having to re heat-treat the frame or other similar shenanigans. I fully expect to be riding this frame in 20 years, if I still want to at that point.

    B) It's not really any heavier in this application. Frame/shock are about 10#, whole bike is 37 or so. Same as any other DH bike. Aluminum isn't necessarily lighter for building abuse-proof bikes, it's just a lot easier to machine for making crazy gussets and swingarms and stuff. So you see aluminum DH bikes because they're cheap to make and most DH guys expect to kill their frames after a season or two and replace them anyway, so there's no need for them to be easily repairable.

    C) Stiffness is mostly a function of tube diameter (this one has a 45mm downtube) and pivots (this is a BMX bottom bracket modified to attach to the swingarm). It's way stiff. You might be able to make it stiffer in aluminum with even bigger pipes, but it's plenty stiff as it is, so I'm not worried about it.

    D) I like working with steel and suck at welding aluminum.

    Does that answer it?

    mmm I thought this was thread was about riding self made bikes. well anyway, steel over aluminum any day.

    here is mine



    stainless steel top to bottom. with aluminum linkage.

    well here's my ride. it's a couple of years old now and still holding up. i built it up under Kish at ubi. i've since flipped the stem and the fork is dead and it needs new breaks too...jeeze. i got a hankering for a new bike.

    Here's my ride.
    My first built,


    A new front end in the making: slaker, stiffer, lighter, sexier...

    I work with aluminium by choice, maybe because I'm a guy from the aéronautic.
    Definitely easier to machine and work.

    I'm surprised at the lackluster response to this thread, but impressed at the number of home brewed FS bike. I'll have to find more pics of mine.

    My submission, from the craptacular to the okay below:

    1) Feldybikes #1, a dh bike I built my senior year of college (early 200) pre (my knowledge of) the framebuilder's list. Steel front (with flux and all), Al rear (easier to machine as previously mentioned. I've since made a better one that's shockingly similar to Walt's (albeit with 26" wheels).
    2) Lame air on a 29er singlespeed. This bike taught me to make my fillets (_at least_ around the HT) bigger as it cracked after a couple of years abuse.
    3) Tandem on top of Mt. Evans. I made this bike with the True Temper tandem tubes and made the stoker TT as long as they'd allow me to. Turns out that's not quite long enough, so a new one will be done at some point in the somewhat distant future. My wife is all bundled up because of the weather than moved in for what was perhaps the most unpleasant descent of my life (including Trout Creek Pass in a blizzard). As the stoker, she fared much better.
    4) My wife on her 29er "singlespeed." In this pic it's a 1x9 (sliders with a hanger) since she dug it so much she wanted to ride it more than her full suspension but wasn't ready to commit to 1 gear for bigger rides like 401.
    5) 29er singlespeed numero dos. This one is (apparently-since it hasn't broken) better constructed, with slightly refined geometry and a more aesthetically pleasing rear end (#1 has *too much* seatstay clearance.

    Trailbike:


    Roadbike:


    DH Bike:


    I'm racing my first DH on an honest to god DH bike at Sea Otter. Cat 1 Men 35-39. Jumping in with the big boys (ouch!). If I do OK, I'll look into doing some NORBA and Northstar races. Since this is my first real DH bike, I figured that I'd buy the frame to see what the state of the art was and how I could improve on it. Maybe have my own frame for next season.

    i built this at ubi back in 99 i think it was. 24" wheeled ss trials bike made to clear 3" tires out back. i mismeasured the seat tube length. it was supposed to be the lenth of the collar lower, i.e: the seat stays were supposed to meet the top tube.



    rode it in several trials comps and alot for practice. still have it. haven't built any frames since, but am hoping to this year.

    new ultra basic

    I got around to building myself a new frame and fork (stem soon) non sus corrected fork, gears only, absolutely nothing fancy but the ride. I ran interrupted housing for all of the cables and welded the stops on, only silvered the seat tube sleeve and h2o bosses.

    My rides

    Built me a couple of SS a 29er and a 26er, they were fillet brazed on a breadbord type table of True Temper tubing, on my 29er I used Pauls dropouts that I added discmount made of 304 stainless and so far it works well, I try to split ride time between the two but for some reason the 29er get used more, thanks for looking.

    Some of these bikes look (and, no doubt, ride) way better than many of the factory machines rolling around. Congratulations, all!

    That Disc Brake mount is slick - I like the smooth combo of the paul's dropouts and the adjustable caliper deal.

    Here's a couple of my bikes-
    My road bike was built in '95 using Henry James lugs and is a mix of 653/531/731OS- it's a sweet riding bike and still rides great.

    The suspension bike is my own open source design. There's a web page I set up here:

    this is my first attempt at a full suspension bike. all made from 3al 2.5v 18g wall, rear dropouts 5mm carbonfibre bonded to frame, cable guides in carbon fibre riveted and bonded. still a work in progress but rides very nicely. 83mm DH bottom bracket my only mistake.caused some unnecessary chain line issues

    Finally, I have a new MTB.

    Steel - yes.
    Wheels - 29er.
    Weight - who cares
    Cost - is all in the wheels
    Value - How can you beat XT cranks for 200 bucks.
    Inapproriate - Rampage tyre. Not Australia friendly.
    MIA - Needs a brown saddle, probably.

    Thanks Vlad. I can't get over how nice constant diameter seat and chainstays are. This frame is even stiffer than the Scandium I was toying with a few years ago, yet still has that nice steel ride.

    Now I just have to find some double butted versions so I can start getting the weight down a bit.

    The rear is plain guage, the seat tube is from Eco [double bulge butted] and the top and down tubes are OX platinum.
