Calling all BF quality/breakage inspectors - need your keen eye
 
As many of you know I augered in on a 18' drop nose first on my 2009 Bighit 3. After the crash a few guys looked at my bike and said i either bent the head tube, fork steer tube, or fork stanchions.

I didn't think anything was bent. There was no binding when I turned the bars and I could not see a bend. Fork travel felt fine. Today I pulled the fork - inspected the steer tube and the head tube. Ran a feeler gauge around the headset cups, all gaps were equal. So far the only issue I could find is the totally bent rear dérailleur hanger.

Take a look at pics below and tell me what you think:

I just ran to the garage and put a straight edge on four sides of each stanchion - they are good. Time to put the bike back together (heal a bit more) and ride.

sscyco 01-28-10 08:54 PM

I always thought that 1.5 head tube - when it came up a few years ago - was a bunch of crap. I think I see it's purpose now.

bikinfool 01-28-10 10:28 PM

Not all damage is visible, either. Does look good in photos. Did they see a bunch of flex during your crash or did they only see the bike afterwards and saw something in particular?

dminor 01-29-10 01:17 AM

^^ Most of us were above looking down - - it all happened pretty fast.

ss, the one thing I wonder, and cannot determine from the available pics, is if you ran a straightedge or line on the centerline of the stanchions/lowers and then did the same with the steerer (dead-flat side view), are they parallel to each other? That's the only way you're going to know if that steerer or crown got tweaked.

cryptid01 01-29-10 08:50 AM

You sent an eighteen footer on a single crown fork? And I catch crap around here for manualing without a helmet. wtf.

reptilezs 01-29-10 08:30 PM

need better pictures

electrik 01-29-10 09:26 PM

Those pictures are no good... you need a square to at least give us some clues about angles... Obviously it's not horribly bent though, but was probably one hell of an elastic collision.

You probably trashed the headset bearings with that impact, are they cartridge? Any rocking when u apply the front brake and push?

sscyco 01-29-10 10:52 PM

No binding or rocking.

I have a dial indicator and a granite slab I can use this weekend. I doubt there is a problem at this point, but It was a hard hit - but I will still verify.

I was looking at that pic........is that 18' in pinkbike feet?

I agree (based on pic) - I'm going by what others said - but I will tell you this - Pics don't do it justice. I did a 12' (measured with a tape - many years ago) and this is waaaaayyyyyy bigger. I will leave numbers out, but I will not do a bigger drop than this.

This has been discussed before. That was my estimation to the rear wheel landing spot in the tranny - - most likelly exaggerated by me by a couple feet. The drop IS big. Come out 66 and I'll follow you off it.

Well crap, don't you know I sold my Bullit sooooooooooo...................i really don't have anything to ride.

never 01-31-10 09:42 AM

I'll come out too and you can use the V10 to follow Doug! ;)

mtnbiker66 01-31-10 12:59 PM

How did you get into this?

cryptid01 01-31-10 01:19 PM

I would be happy to survey the drop and answer the question once and for all. Someone send me a plane ticket.

dminor 01-31-10 03:17 PM

^^ C'mon folks, let's make this happen. Since I couldn't get Cheap Trick to do a benefit concert for this, I'll start it off myself. I'll pay for the in-flight beverage service. There - - who's with me?

Thanks! That'll likely end up costing more than the ticket btw.

bikinfool 01-31-10 09:24 PM

So where are the pics of the drop?

I'll sell you a medium Blindside frame reasonable :D.

Daily Ride reports thread, last pages; although there are others. Google image search for Beacon / Spokane / Girthmore. There are a few particularly of a kid named Skye sending it.

It's bigger than it looks; and, of course it looks bigger than it is when you're up top looking down ;).

Just hop in the Bimmer with 66 and do a road trip.

This is true. Come to think of it you're a much bigger guy than me so the V10 wont work.......but there's a Stinky hanging out somewhere around the house if I can get it away from the girlscout/A.K.A. microwave.
My trails are under about 8" of snow againg soooooo.....roadtrip!
