    Carbon fork crash carnage calamity

    Just thought I'd post some pics of my crash last year.

    To be crystal clear: this was from a CRASH. It is no fault of the equipment and, in fact, it saved my ass.

    No, but seriously, I CRASHED.

    With that being said, here's the story:

    This happened in October last year. We were out getting in one last ride on snowy and icy trails. My rear brake was totally gone -- it had been going for a while but I was planning to deal with it in the off-season.

    Came into a section of trail with a right hander into a steep downhill into a hard left-hander. Well, the downhill was glare ice. Only a front brake which was doing nothing, so basically I had to ride it out. Went into the woods and hit a tree straight on with a lot of momentum. I was braced for impact so stayed on the bike while the front end soaked it all up.

    End result, as you can see, is that the alloy fork crown bent. I was impressed that the carbon was unaffected. I haven't looked too closely at the wheel but it seems fine and the frame is good.

    Given 250 lbs. of bike and rider piling into a tree at speed I'm pretty damn pleased with the end result. Chalk one up for the Pro carbon fork. It inspired enough confidence that I plan to buy an identical fork to replace this one. The old fork is going to get built into a truing stand.

    I just pulled the bike down to start getting it ready for this season, so I figured I'd post some pics.

    That is pretty impressive. Not where you'd expect it to fail first.

    I don't know what is funnier, the pictures or the fact that you did that to your bike and just left it for 6 months.

    No story about you so glad you must be ok.

    You knew the brake was already failing and still rode the bike in the worst conditions possible? Looks like the fork hasn't completely failed. If you were to turn it 180 it would have a nice offset and good trail figures. Could probably squeeze another 6 months out of it too.

    Wonder what would have happened if you'd had a carbon crown...

    Damn. That's a pretty good endorsement for that fork. Glad you came out of it unscathed.

    "carbon cracks on impact"

    "aluminum snaps it doesn't bend"

    This one might throw the mtbr materials "experts" through a loop.

    Probably wouldn't have crashed if you were riding with a seat anyway.

    Lesson learned. Brakes are good things to maintain properly.
    I see hills.

    I want to climb them.

    Holy crap ! I can't believe your wheel is still round, that looks like a big impact.

    Riding without a working rear brake and without a saddle - that's what I call tough.

    Crazy, please tell me what rim? That's pretty impressive it did not ovalize on impact.

    Story not accepted. Looks like a JRA incident to me.

    So not even so much as a smooch of tree bark? Catch your seat in a bad spot? (I almost got stabbed in the femoral artery when mine broke off the rails) Glad you came out OK.

    I guess if you do some kind of armchair crash analysis the failing fork probably resulted in the least potential of injury to the rider. If the wheel had folded, he'd have likely gone head/collarbone-first down into the tree with his center of mass lined up with the point of impact. If the frame (headtube junction/downtube) had failed, he would have been out one bike AND the fork would have probably been tweaked. Plus, forks are easy to replace, and not crazy expensive. I'd say you got your $$$'s worth out of that one. Where do I get one?

    I know a few 4x4 guys who have their drive lines and axles all beefed up, but use standard locking hubs. The hubs are the most likely part to fail - intentionally, like an electrical fuse. They are also the easiest to replace and you can still roll even when broken. A broken axle, driveshaft, or gear usually renders you immobile (at least less-mobile), and might break something else when it goes.

    PS - order some brakes

    That's cool, thanks for sharing..pretty scary when you hit a part, going fast, and can't stop. I remember preriding a race somewhere and hit some slick rock(from water/mud) going downhill and couldn't stop and flew off the bike a good couple hundred feet. I think I broke my collarbone, but never got it fixed.

    That crown must be pretty soft if nothing else broke or bent.

    Glad you're ok!

    Definitely check the headtube for ovalisation, as it appears the steer tube bent as well. Hopefully it just messed up the headset cups and/or bearings. I'd get the headtube refaced and reamed just to be sure.

    I guess "braced for impact" means a$$-puckered so tight that it ripped the seat off when impact was achieved.
