A side car for your spare bike. Genius.

Hawt, but what's the point in the crank setup on the black one?

Its running an internal gearbox.

If we're posting Nicolai's now these have to make an appearance.

Those are mental.

the green one is mint.

Closer to British Racing Green, but I take your point.

Is that a Rohloff in the middle?

Yeah.

This is actually the one from the nucleon TFR (the black gearbox one posted earlier. The one I posted doesnt have it sealed inside.

does that give better weight distribution for jumps having the 10sp hub in the middle of the frame

More to the point it stops you dropping a chain. There is no need for a chain tensioner because the chain length is constant, while having a raised suspension pivot point.

14 gears is too many for a DH bike really, so they now build one with G-Boxx 2, which only has 7 speeds. This is far simper housing 14 different size sprockets and 7 mini chain runs, all internal.

Rohloffs are 14 speed.

Other benefits

1: Reduced unsprung weight (by about 400g) gives better wheel control
2: No vulnerable rear derailleur to get smashed by a rock
3: Can change gear while coasting
4: Chain drive tension doesn't load suspension. Complex (heavy, flexy) multi-element linkages are designed to get around the problem with varying degrees of success, but making the drive sprocket and swing arm pivot concentric is a perfect and simple solution.

Im afraid I disagree with this comment. There were a few frames produced that had the swing arm pivot as part of the bottom bracket shell. These suffered really bad pedalling induced suspension bob. The best rear suspension designs as far as isolating pedalling forces go are the ones that serve to increase the BB axle to rear wheel axle distance under pedalling load. Horst link designs for example. The Nicolai's wouldnt be too bad due to having a fairly high pivot point, but still not perfect. If the frames design has concentric drive sproket and swing arm pivot, there will always be a turning moment applied to the swing arm.

I agree with the other comments though.

so happy we're discussing mtb full-suspension details on fixed gear and single speed forum's bike porn thread...

Oh lighten up bozo-breath!

All bikes are good.

Apart form unipac but even cycling plus think they're ok

on with the business - top of the line classics from Ukraine

I dont see the problem, if it is porn it is good, and that is porn

Nicolai frames are to die for and their website is great too.

One day.
I cannot believe you didn't post the twin top tube hardtail. You are DTM.

...I dont see the problem...

me neither, on with the good stuff - same maker as top of the page frame

those cranks look cheap and nasty

lol

...Curtis Sidewinder. Downhill 'sidecar' bike, only two ever made. Based on the SuperX which I had a few years back and is a great bike. This one's on Ebay and I'd LOVE it, but sadly silly money:
