Still recon the RC200 is the best looking frame ever made.

Owned one for around 3 months, had to sell it on, ride was wayyyyyyy too harsh for me :(

Second best looking frame ever made. ;) Still the San Andreas for me.

I didn't like the ride too much ,either. Took one out for a ride, then took a Funk. The Funk was in a different league.

I reckon it's a cyclists thing. They just like shiny alloy tubing. ;)

I like shiny carbon tubing more :D This pack has magnesium ally tubes so hopefully will be a little bit lighter than your average throwback. Will give me something to play with though. If the concept works ill let you and @gixer debate the ramifications of carbon frame meets mountain terrain :D

:finger: :whistling: :p

Love carbon fiber and i recon it's a great material for soooooooooooo many things.
The fact that you can lay up the fibers and layers to give as much rigidity or flex in areas make it great for bikes.

Problem i've had with the material on MTB's is it's lack of impact resistance.
Recon i've had 3 carbon fiber MTB frames every single one has lost chunks from impacts.

I bought one from the top MTB maker, a large stone got flicked up by the front wheel and took a chunk out of the downtube ON THE FIRST RIDE :mad::mad::mad::mad:

I still recon it's the best material for road bike frames.
For me Ti just kicks ass for MTB frames though.

Great impact resistance, doesn't corrode, no paint to chip, a quick going over with some wire wool every year or so and it comes up looking like new.

My full susser is Aluminium (Trek EX) the paint is chipped everywhere and it's only 7 years old :(
My Diamond back axis TT (Ti) is well over 20 years old and looks like new :)



A carbon fiber rucksack frame is going to be a tough project.
If you get it made out of CF tubing then the joints are going to be a weakness

If you get it laid up as a one piece frame the mould alone is going to cost 4 figures

Even then in my experience the edges/corners are going to be prone to damage.


Steel would be the easiest, some thin gauge Reynolds tubing should be fairly lightweight.
You could even braze or butt it yourself.

Only downside would be rust eventually.

Yep i cant disagree with any of that but im still having it in carbon because i can (well depending on the quote lol) deffo wont be one piece but i dont think engineering the strength in will be an issue. mmmmmm black carbon with an orange pack on it. im dribbling lol

I've got an ancient MTB mag somewhere previewing the first ever ti Marin bike, I'll see if I can find it in the dungeon sometime.

I had a Raleigh Technium Chill at the time, I thought that was the bees knees with it's ally frame. There wasn't a lot of choice back in the late 80's, Cannondale and Pace were just emerging but were silly money. I always wanted a Specialised Rockhopper but my dad wouldn't buy me one, so I got a job on the local milk round but sacked it after a week of getting up at 03:30

Had a viscount Fargo as a kid, must have been around 1980, they weren't called mountain bikes then :bag:

Was a year or 2 before the Raleigh bomber came out.

Was pretty cool cause all my mates had BMX's, but i lived further away up some big hills so used to ride this more than my BMX.
After a year i recon there was more weld on the frame than frame material :whistling:

Dunno about the older packs, but my Arcblast has flat plastic rods, my newer archaul round plastic rods.
No CF in them

you're right on a closer look. i thought they'd gone to carbon but it seems not. Colin Ibbotson is using an internal carbon frame but does make some comment on it not being indestructible

Quote Zpack FAQ's -

"
What do I do if my frame breaks?
It is uncommon for the Carbon Fiber backpack stays to snap, but it can happen. Dropping the pack to the ground with a hard jolt could do it, or slamming the pack in a car door, trunk, or airplane overhead bin could do it.

The good news is the frame pieces are easy to slide out and replace. Just shoot us an email and we will send a free replacement piece.

The on-the-trail fix is tape a nail or tent stake around the broken stay as a splint. You can hike for months with a splint if need be."

??? - I've only ever had a brief glace at one so I'm certainly no expert. :)

Before the Arc Blast, Zpacks used to do a pack with a frame made of holow carbon rods similar to arrow shafts. I dont recall the name. The joints wrre some form of plastic, though.

Nostalgic stuff, and you hauled the same caravan over to Greece on the back of the BMW recently too.

The England & St.George stickers really gave the old van a facelift. :thumbsup:.....:tongue:

To have proper closure i should have hauled the old van to Greece with that bike :woot:

Some great memories in that van :cry:

856g. It's supposed to be 50l but looks more like 40. Should be a nice build and would hope to drop a bit more weight although needs hip belt adding and better shoulder straps. Just got to decide in fabric. Will weigh frame on its own when I've got time to take apart. Just ordered the other 2 the guy had :)

^^^ Is the frame solid ? My old Cobmaster the frame wasn't that good it 'rattled' and the fixings for the sack bent and kept 'undoing' themselves. :cautious:.
