Surely if people built downhill bikes, like the pro's, strictly for downhill, they would use single-speed, it would save weight. No they use gears

they use gears coz with single speed the chainstay is gonna get smaller as it compresses so the chain will just fall off running single speed

They use gears because you're much faster with gears.

So your saying they can use single speed then but chose not to ?? I'm saying that almost every full sus dh bike cant use single speed because the chain stay gets shorter when the rear sus compresses and as a dh bike is set up with a lot of sag.

Don't you mean they get longer? Which would cause the suspension not to compress and/or break the chain.

If the chainstays got shorter, you would have really damn long chainstays so the wheel doesn't hit parts of the frame..

it's fastwer with gears. Dh racers don't just use one gear when they race, they use 3 maybe even 5 different gears depending on the course. Now that xc and uphills are being added into many dh races ss just will not cut it.

The chainstays get longer, the chain gets "shorter."

Then why is it called chain growth, not chain shrinkage?

I was shocked... thought I wouldn't reply in an angry matter.

Thanks people for clarifying chain growth.

WTF are you guy's talking about?? it's a hardtail remember?? you could easily run a SS on it. as there is not Chain growth and no compression in the rear,

Disregard if you're on about something else.

Notice up in the quote tree that we're talking about downhill bikes.

No worries.

I'd like to note, after riding Single Speed for a few months, then switching to gears.

It's not worth the weight savings, especially if you can afford a chain guide.

i would strongly advise against it
most hardtails cannot take the strain of dual crowns
