Thought this was worth a discussion .. frames look quite interesting.

Nice, but I can't say that I agree with the "mock weld". It's a personal thing but I really don't think it helps asthetics, I'm a much bigger fan of the the clean hydroformed tubes on the haros. I'm with Ty though, the dropouts do look pretty nice.
Edit: why does it say no gears in the specs when there appears to be a derauiller tab on the dropout?

Ultimately they've just chucked in a big bulky thing at the top with fake welds right?? I personally think it doesn't look any better than other planet x's. Still a farkin sweet frame tho...

super huck
yea? im not sure if i like it that much... i like the look of conventional frames more. thats a bit weird, funky drop-outs though!
The fake weld is disgusting, why didn't they create either smooth flowing lines, or big chunky box sections? And another thing, adjustable dropouts are all good, but if you're going to have horizontal, at least make it "infinitely" adjustable to allow for single speed use :twisted:

Boooo. Why try and make a frame that "looks" cool? I would very be surprised if that fake weld makes the frame any stronger (I know it's just there for looks, but I will take a stab in the dark and say that if anything it weakens the tube - albeit minorly seeing as it goes lengthways).
Boooo. (bs).

peachy
Ripe 'n ready!
i beg to differ. why would a pro company like px weaken their frames. they don't just go and make a frame, they do a shit load of research. so obviously through their research and testing etc they've come to the conclusion that its strong like elephant.... elephants!
i reckon it looks dead sexy like a tiger, grrrrrrr

obviously the gears = no thing in the table at the bottom is a fuckup.
as for the fake weld, it says for asthetics and performance, so i'm guessing it does perform some structual function.
and as for the bolt up sliding dropout setup, saying this will effect single speed use is plain wrong. each chain link is 1/8" long, meaning no matter what combination of gears you use, your chainstay length will fit into some multiple of 1/8". and to me, those bolts on the dropout look to be 1/8" apart. thus meaning, you should be able to get near to perfect tension on any gear combination.
as has already been shown by the letoy 4 prototype, bolt on dropouts are going to be the next big thing. they allow for perfect calipar & derailer positioning, while still allowing for adjustable chainstay lengths and singlespeed.
it'd be fair to assume, someone spent a lot more time thinking about the design of this frame, then you did thinking out your post bitching about it.

1) Even if that was correct, you're not accounting for chain stretch, which trust me, will make a very big difference in not a lot of time.rad rob said:
2) This is just the way I'm seeing it, and I'm not really thinking straight at the moment, but it seems to me as though your reasoning is accounting only for the length of the link if it was parallel to the chainstay (well a line from the centre of the BB to the centre of the axle). This is most definately not the case on a bike, as the chain is firstly running an angle from the sprocket to the chainring (as they are of different sizes) and then is running varying angles as it moves around the ring/sprocket. In fact you won't find one link which is parallel to the "chainstay".
This is why I think that your reasoning behind the 1/8th" spacing isn't quite correct. My experience trying to set up tension on BMXs tells me that you need much finer adjustment than 1/8" too.
Thankyou wombat for raising the exact two points I had in my mind, but couldnt be bothered typing last night 
The bike is probably good as a singlespeed for only one defined gear combination, and one defined amount of chain wear. Don't beleive chain wear will affect it that much, well, my brother spent an hour yesterday going through all our old chains, trying to find one that was worn enough to allow him to run a singlespeed on a bike with vertical dropouts. He suceeded, and it was quite amusing to watch him try.

They SAID "aesthetics and performance". Just like Specialized CLAIM completely braking-independent suspension movement. They're not gonna say "well we did this because we thought it looked cool, but in actual fact it weakens the frame 5%" are they. I don't question its strength, I question why they bothered putting the fake weld in. As I said, I can't see why it would make the frame any STRONGER. To be honest, I'm not much of a structural specialist at all (talk to Grip about that one), but in very basic terms - if it WAS actually stronger to use that mock weld, why don't they use it on every single tube? Obviously it doesn't cost that much, because they were willing to use it purely for aesthetics, so why?rad rob said:
