apparently rock racing thinks so...

what is the context for this?

I think its a sweet idea.

Trek has one too..

My brother is a rock racer.

Alloy SS cassette hub; alloy deep section color matched rims

From the parts list of that bike. A.K.A. its a single speed, not a fixed.

Rock crawling?

Why is this even a thread? Are new bikes with semi new tech worthy of creating a thread?

get up on the wrong side of the bed there bozo? have you read some of the other threads in SSFG?

i think its a sweet idea, and i'm excited about more companies jumping on board with belt drive, its a nice chain alternative, and i bet its stealthy quiet and smooth. time will tell if these things catch on.

I always thought that the trek carbon drive was FG? Is it not?

Not according to their component list on their website.

It's a fine singlespeed bike. I am not sure yet, how I feel about having to open the left seatstay when having to replace t he belt.

Also, are those chainstays or beltstays now?

What does worry me is the sand that this belt might trap under the teeth of the chainring and cog. That could reduce the working life of those components. Luckily, since it is not a fixed gear bike, you don't need to have the belt constantly running.

Apparently, he doesn't!

Im not posative on the one in the picture but according to this article, They are offering a belt drive fixed gear.

Since that picture is the only reference provided by the OP, that's the only thing I commented about. To illustrate this, let's say the OP started a thread titled "It is true: pigs CAN fly!", and then put a picture of a wild boar ****ting in the forest, you would probably comment that that's definitely not a flying pig.

As for you not being positive "on the one in the picture", I need to point out that what is visible is very clearly a cassette hub covered with spacers to correct the chainline.

motorcycles do it

Well what do you want me to say. I have yet to have my coffee this morning.....ass.

Historically, motorbikes used belts for transmission. But belt drive has been almost universally replaced by chain drive. Do you wonder why?

I'm sure my wife agrees with that statement.

BTW, you can write "ass" on BF? How about dick? Penis? *******?

OK you guys, cool it!

so what exactly are the pros/cons of this belt drive?

Why does the left stay need to open?

Regarding sand, I don't see how a belt is worse than a chain. Lubricants trap some nasty stuff on a chain, especially the lubricants I use when conditions are nasty enough to catch lots of road grime in the drivetrain.

Since a belt cannot be broken and reasembled like a chain, it cannot be removed or installed without passing through the seatstay.

Wouldnt that mean the right stay needs to open, not the left?

My bad. I missed the part about "left" Yes, it is the right seatstay.
