martenistic stainless cage?

[MoparManiac]

I was just thinking the same thing.

And I've never heard of mountain bikers dropping off ledges square onto rocks with their frame.

Either way, doesn't sound like a good idea to me.

so you use 1/8" tube for your sliders? or do you use 1/4" wall for your cage?


and again, apparently you havent been mountain biking

when you're bombing down a rocky trail at 20-30mph, at times you fall off and the bike doesn't land in a cloud made of marshmellows. i've tossed a couple bikes off a ledge taking some switchbacks a little too hot.

It would be cool as a bolt in/on like the rock hard cage. I would do some design improvements though.

ditching your 22lb trek isnt comparable to rolling a 4500lb rig. stick to the materials that are proven to keep your sorry ass alive if the time comes. most WRC cages are T45, and they do a pretty damn good job. if they could save 5lbs by switching materials, they would, but no one there is compromising by sacrificing safety.

Make your cage out of limit straps

Make your cage out of limit straps

bump stops would be more effective.

It will fold like a taco!

fair enough, which is why i asked, i dont know what real rigs use. i only see what cheap ass xj owners use and i don't like the argument that it shouldnt be used because it's different, i would prefer actual factual data to back up why it isn't a good material when applied properly.

but the argument was made that the stainless couldnt take a ding, and i'm sure it can as well as chromoly. both have failed plenty of times as frame materials, but with respect to that, you're usually talking about a pretty good impact, on very thin small diameter tubing. and usually the breaks are due to leverage/torque, not impacts (unless it's carbon fiber). chainstays for example are typically .625" diameter, ovalized, and bent, maybe .03" wall? i lost track how many times they've been bounced off of rocks at a high rate of speed, and not to mention the strain disk brakes put on them. same with head tubes, you have what, 38" of leverage on a short headtube welded to the thin top and down tubes, dealing with running into trees, rocks, and heavy braking from disk brakes? that's some serious abuse, and i can promise that 1020 wouldn't handle it, or they would use it on more than walmart bikes. to say it isnt a valid comparison isn't neccesarily right just as it wouldn't be right to say steel shouldnt be used for hardware because a 10-32 alloy bolt isn't as strong as a 1 1/4-12 aluminum bolt.

 

[souske]

Uh oh! Don't go Srimes on us Dan!

 

[Vanimal]

Look, i didnt ask how to limit my travel, i asked how to keep my springs from falling out.

 

[souske]

No, that was the motormount from stock shackles thread.

what are you going to do about it, shoo me out of your summer home with a broom again?

 

[souske]

E'ry time a bell rings, an angel get its wings

 

[kastein]

is that actually you souske? You've got a better unabomber beard than I did in college.

 

[Vanimal]

you better believe that's actually him. i've seen blue jays fly out of that thing.



you know i left those bells in for that whole day of wheeling, right?

 

[souske]

Yeah, that's me

I guess the better question, is what had you pictured?

 

[xcm]

Did you seriously just talk about the 'strain' disc brakes put... ON A BIKE?

 

[Vanimal]

Did you seriously just talk about the 'strain' disc brakes put... ON A BIKE?

uh, yes, same diameter tires as on a lot of jeeps but with softer rubber, going down slick rock or pavement and jamming on the brakes at 30-40mph.... if you don't think there's some decent forces there for the size of the tubing, you're nuts.

 

[Vanimal]

Yeah, that's me

i always pictured you as an asian or latino ladyboy.

 

[souske]

Lol! Well 200 lbs of A-hole, on a 20 lb bike, its no wonder you would need tubing 1/3 the thickness and diameter of a proposed exo cage for the same guy, in a 4000 lb jeep?

Same thing right? :eyes:
