Whats the deal with Singlespeed full sus bikes? I mean, really!

And surely wouldnt the chain tension decrease when the suspension is active?

What bikes FS SS bikes have you seen? The only one I know of is the Kona A:
http://www.konaworld.com/2k3/2k3_a.cfm and it looks like they don't offer it anymore (can't find it
in 2004 bikes)

I ride rigid, but I wouldn't mind givin' the A a try.

The "A" is available frame only for 2004

Can somebody explain what it is with "I-Drive"?

The guys at the local LBS have a few in stock - but even they couldn't come up with a plausible-
sounding explainatin for what's going on down there...

A cruel joke.

Not on a URT.

No, sadness.

It is a unified-rear-triangle design with a bizarre floating bottom-bracket mechanism to make it
seem less like a URT. A lot of work for little gain, if you ask me.

Speaking of manufacturer's FS SS bikes, Norco has added a bizarre but wonderful new machine to their
already fairly bizarre "Supercross" lineup. I give you the Norco Four20:

http://norco.com/bikes/2004bikes/four20.htm

Looks like a URT design, but it has a heavy urban/dirt jump orientation. Not many singlespeed fans
are likely to desire the axle pegs or Gyro cable rotor.

No, I'm not sure why Kona and Norco, located about 40 km from each other and within driving distance
of the Shore, both have FS SSes. I suppose if you're not climbing the trails under your own power,
you only really need one gear.

But hey, it's steel,

Look at the chain droop. That thing is a derailment waiting to happen. I don't care if people want
to do this, but FFS do it right.

And how come the crank isn't blue?

Not if the pivot point is the center of the bottom bracket! I've often wondered why FS mtn bikes
weren't designed this way to begin with.

Because it doesn't work as well as you might suppose?

If Rube Goldberg designed a suspension system, what would it be....

Do you mean the problem of designing it around the bottom bracket shell or that having it pivot
where it won't alter the chainstay length is a bad idea?

Hey that's interesting. I didn't know that manufacturers were doing this. I don't know Rotec but
I remember the Diablo. Can't recall it's design, tho. I couldn't find any info about it on the
Jamis site.

I still do not understand where the problem is (except that it is full suspension, lol). If you
are concerned with pedaling efficiency then FS ain't your thang. FS is for DH and this seems
like a superior design to me. Back to singlespeed, I think a design like this is the only
practical solution.

If you don't do DH and just need a full suspension bike to absorb the shock from the little pebbles
on the course then I guess this is not a good design for you. The flaw then becomes your old
dilapidated back and not the bike! (A little humor gents, don't flame me!)

Of course what's most obvious is that only a few manufacturers adopted this system and now it
appears to be abandoned. I can specualte that it must be a poor performer and/or be too expensive to
manufacture and maintain.
