    an occasional rare event.....

    one of the nice things about working at a shop is that you get to see LOTS of variation on a single theme....you'll see things worn in all manner.....things break and you get see them cracked and sometimes you get to see them straight up fail.....

    last week a small fleet (5) of bikes used by security guards for a local mall come in.....i WISH i could have taken a picture cause these things were not only beat the fuck up but had some interesting points of interest....like the bar ends that pointed straight up.....nad the frames that were scratched to hell and covered in a sooty grime.

    basically...these thigns were fuckin beat to fucking hell......to put it mildly.

    so the task was...get these thigns running and running well....while it would have been more cost effective to just buy new bikes....whoever is in charge of these bikes decided just to get them fixed.....each bike with labor and parts came to between $250 and $300. times five and you get and idea of what all these cost.....

    but shit, it isn't so much to cost but the TIME it takes to work on these sorts......two had to have their cranksets cut off with a dremel since the mechanic saddled with the task didn't want to dick around with gear pullers or ball peen hammers and chisels......and rightly so......

    it's one thing to have fun destroying a part just to get it off the bike but after 2 hours you 'd just want to be done with the damn thing and move on to something else.....

    so two cranksets cut off.....several wheels repalaced...cables and housing for brake and shift for all the bikes, new tires and tubes on some and new shifters on others...... it was a death march.....

    the most amazing thing was a particular front wheel off one bike......the mechanic working on it noticed that the hub axle was probably broken....

    broken hub axles on front loose ball bearing hubs isn't uncommon. lots of threads are cut onto those axles so there are lots of points for them to fail at.....in most cases....the QR is too loose and the axle gets beat by the fork dropouts. this usually fucks up the dropouts but who's keeping score, right?

    OR.....the hub is ridden loose and again...the axle takes a pounding.....

    anyway.....this front wheel was special because as soon as the QR was removed....EACH end of the axle fell out the end of the hub! leaving the center portion and the balls rolling around in the shell!

    if you've worked on loose ball hubs then you know this is something that's VERY rare.....every mechanic there noted that they'd NEVER seen this before.....

    i sent of the pics to as many mechanics at USAC and UCI as i guessed would savor such destruction and they were all stunned.....most thought it was a gag......and not a single one had ever seen an axle broken in this way.....

    so here are the pics......first up...the wheel.....now....some may look at this entry level Deore hub and scoff.....but you'd be surprised at the brut strength of the steel used of these axles.....they are a BITCH to grind to shorter lengths......





    two shots of the axle....with and without flash....the ends of the axle are still threaded to the cone and locknut.....so the axle snapped at the end of the cone.....

    seriously...this is fucked up! just look at all that grime and smeg all over the locknuts!








    just amazing.....especially when i remember to take pics of stuff like this......

    i'll make sure to takes pics when i can remember to and when it's possible......
    It’s impossible to rate welding/brazing quality by looking at a finished frame joint, even an unpainted one. Files, sandblasting, and a good paint job can take care of that. Such a joint will look stellar unpainted, but won’t last. Yet people all the time look at frames and say, “Nice welding/brazing…” The point isn’t to make you paranoid, just to stop saying things like, “That’s nice welding/brazing,” when you see a painted/unpainted frame. -- Grant Petersen

    Security bikes are the best...

    "gears won't change. can you fix it?"

    "uh...your hanger is bent so bad the cage is hitting the spokes...uh....well, and the cage is bent. your chain...um, well it's trash, and this cassette is the most worn cassette i have ever seen. did you know your big ring was bent? and trashed? oh, your brakes rub? well, this wheel has 2 flat spots, and is pretty much tacoed. looks like the lockring is loose, too. and that rattling you hear is your headset. it's...well, at the very least, it's loose. um...more than likely, it's toast.

    but yeah, i can adjust the rear shifting."

    -dustin.....hahahah!!!!!! oh man! how many have you worked on so far?


    yeah...i think the ONLY thing that didn't get any work done on it were the frames.....they were beat too though.....

    you forgot one!

    and for what it's worth i can't recall ever seeing an axle break in three like that either. part of me is imagining i have, but i'm pretty sure my mind is just making things up. i have seen a guy come in once every two weeks for about two months with a broken front axle, though.

    the way they had their bar ends pointed, I thought it might be some weird trialsy thing.

    you should pass my phone number on to them.

    i'm not sure i'd actually touch them, who knows where they've been, but i'm sure they'd be fun to watch.

    fore....number passed on....enjoy!


    -dustin....i'll just say yes.....i gave them your number too.....enjoy!




    man what a killer week....i'm really starting to get back in the grove of working at a shop......

    first up is a wipperman chain that looked like it'd been whipped with another rusty chain. worthy of note were the several gouges on the outer plates from forced shifts. damn! that had to have been one hell of a forced shift! shitty pic though....






    i think this one was simply...the guy hit a pot hole and the polt hole won........





    this one had to be the weird one for the week.....i unwrap the tape and what do i find underneath? Mr.Tuffy liners! i was stunned. now i know that people have wrapped stuff under regular bar tape to beef up the size of the bar for some reason or another.....typically, i've seen cotton bar tape.....very common stuff about 20 years ago and still useful today.....but it just seemed odd to buy Mr.Tuffy for this reason....or maybe it was old Tuffys and they just figured it'd be a good use.....at the moment...i didn't really get a chance to think about that.....it was just a weird thing to find under the tape.....






    today had to be the biggest shit in the pants cause i ended up working on a tandem RECUMBENT! if you've worked in a shop and had to work on one....you know 'bents can be tricky cuase they use uncoventional parts and sometimes funky ways to get things working. the good ones aren't so bad but the bad ones are just a pain in the ass!

    anyway....so i'm working on this tandem recumbent and it goes well....loose headset....new rear cable and housing and some brake adjustment and a few other things....not too bad.....


    but best of all is getting to see the managers goof off on it.....that's an upside down set of bar ends on the ends of the capatain's bars and a big ass kick stand bolted to the front fork.....also note worthy...it's got a rigid front end and a about 2.5" in the rear......







    speaking of goofing off......a cruizer has never been weilded so deftly as it was in the hands of Cracka B.....

    both are 2nd level tune-ups (typical adjustments, bearing adjustments, wipedown), both require chains, and one requires new shifters. both look fairly old, which worries me the most. neither are the $3000 Bacchettas that'd be somewhat "easier" to work on.

    i need a camera too...

    the other day i was swapping cranks on what looked like a simple pedal strip out. the right pedal was already out and the threads were stripped on the crank. so i go to pull the left pedal and it's giving me shit. so i bear down on it and it tightens. what the hell? i look at the pedal that's already been removed from the drive side and it has an 'L' stamped into the spindle. jeez.

    -dustin.......you'll have to post on how long it took you to work on those two cause i bet it turns into an all day thing.....and afterwards....you'll want to go and get blasted and get in a fight to help take the edge off the day........




    young...i'm just using the shop one cause they use it for warranty photos instead of sending stuff through the mail.....

    so did you guys sell 'em a new crankset and pedals or did they cheap out and get some $20 cranks?

    George....dude..trikes are one thing.....and....personally.....they are easier to work on since i don't need to put them in the stand and drum brakes aren't a big deal either...typically needing minor work to get set right....

    but some of the others (bikeE, ant he others i don;t bother to remember the names of) are just a bear. they consume lots of time and typically...it takes most mechanics a while to check everything over....and even then...you find something and try to fix it...only to find out to have to stop right there cause you found something else that needs fixing first......multipy a few times and some bents can be no fun at all.....


    liek that Stones album/song...."Some Bikes"...


    some bikes give me headaches

    some bikes break my hands

    some bikes i'd prefer to burn

    some i'd love to smash against my stand

    fuckin fuckity fuck. both were due at 4, and since i pulled the first one and had the special clamp, i got to do both. got finished at 5:30. i had to take a break from them. bikes like those seriously piss me off. the one with the new shifters had a trashed rear derailleur and cassette. so, of course, shifting sucked and i spent way too much time trying to get it right. the other one needed it's seat moved forward. i figured a simple bolt or 2.

    no, that'd be too easy. 4 bolts and a threaded pin just to loosen the seat, then i had to loosen the kickstand. easy enough, but after 7hrs of crap from these 2, i was about to start pulling hair.

    they were both this guy:



    oh, and don't get me started on the stupid ass cable routing.
