my crash...

[grncivicdhr]

ok, i'm riding some pretty bas ass down hills cuz i race mountain bikes and i'll be racing downhill next season (i hope) as well as some more cross country. as i'm flying down a hill i come to a drop off i hop off all the time, no big deal at all, not even 2 feet. i wipe out and go fucking flying, lucky enough not to have broken any bones. so i turn around to see why i crashed out so bad and this is why: www.philly2600.com/bike.jpg

Well, huh.

Yeah, that could probably do it...

[Toksin]

Yyyyeaaahh, I see your problem right there.

[Rbraczyk]

Holy S dude. The best I've broken downhilling are shocks. Thats a clean cut. How the F did you do that?

[Andydg]

Damn...I've broken some bikes in my time but nothing like that.

[Suislide]

what kind of bike was it, man? there must be some sort of warranty on that since it could have been a defect from the factory or something.

did the weld snap or did it just snap in a random spot?

[grncivicdhr]

pretty much the weld broke. its a marin which aren't bad bikes. i got it from REI. the head tube on this bike wasn't gusseted or anything so it probably couldn't put up with the abuse that i can dish out on a bike. it was around a $650 bike. i brought those remains in and the gave me a straight up trade for another marin thats a much beefier frame, gusseted and all. i just raced it today and it was pretty nice. retail on the bike they handed to me was $1100, but it was on clearence since it was the last one and marked down to $600.

but as far as how i did that, i'm not really sure. the rep for marin seems to think i was a bad weld.

[s4fanatic27]

Yea, etither bad weld or a hitman wanted to see you dead. JK
That thing just snapped ...damn that would be scary.

[Jonno]

Hmm, I wonder what the problem is...

Are your tyres properly inflated?


I wouldn't mind getting into some Downhill mountain biking, I have a $1150 Diamond back racing BSX sport. Nice bike but the crank has been making some weird noises lately, and the disk brakes are a pain in the ass to set so the disk wont rub too bad...

[Rbraczyk]

Hehe, I'm runnin an I-drive GT, which has to weigh close to 45 pounds, and will bounce over that once I get a Boxxer. Why are you running a hardtail downhill?

You'd be amazed but unless the factory rep approves the replacement, it probably won't be covered by the warranty.
Most race level mountain bikes aren't warranteed for 'conditions exposed to while racing'.

Wait til you start racing...thats only the start....just snapped the bank end on an Intense M1...Id post a pic but Ive got issues with the comp at the mo. Over here in the UK, Marins have a pretty bad reputation for being 'crack n fails' along with cannondale and a few others. Cannondale aint bad but from experience, marins aint good dh frames...or even hard xc.

Oh, and freakray...your point is pretty true unless its a top end race frame like an orange or an intense/foes etc. Intense shipped a new seatstay to me free of charge over the summer which was pretty cool of them...and that frame has been abused with racing and 15ft drops for the last 20 months..

P.s. Jonno, what discs are you using, I might have a few tips to help.

Umm, its the system that came on the bike, some Tektro Mechanical job. Pretty sure its a 6 inch disk on the back, and a 7 or 8 inch disk on the front. I would be alright if I didn't keep bending the damn things...

I can't speak for the other bloke, but I use one because of its strength, and IMO Hardtails take less effort to get going (since with rear shocks you would be loosing a fair bit of leg power in the suspension). Plus, I have had friends who advised me against a dual suspension, since their rear suspension kept screwing up.

110mm of front suspension travel (if I remeber correctly) is enough for me anyway.


Anyone know how to get the sealed bearings out of the crank to lubricate them? I think that should help with the creeking noises...

Yeah, some companies will do that as a service to the customer.
I've has parts shipped globally my Giant when the local agents couldn't get me parts. I contacted their corporate office and they sent me a replacement AND a spare!

Plus, the M1 is a pretty solid frame, so I expect they gave you the benefit of the doubt when it gave in.
Funnily, I've never set eyes on an Orange which is weird since a friend of mine rode one when he raced for Team Global.

You need a bottom bracket tool for the specific BB your bike has.
It's probably not the bearings anyway, it's probably the contact surface between either the crank arms and the BB axle or the contact surface between the BB and the frame. Pull it all apart and put some grease on the contact surfaces.
