Belt drive would be great! It would be lighter, cleaner, and more quiet that a chain.

Hrm, I like it. Belt-drives are supposed to be fairly maintanence-free and very quiet and the parts can be made from carbon fibre, so they can be very light too. Nice.

All one needs to do is add a spare belt in the tool bag. No messing with chain tools and greasy links.

No. Think of the drive-belt on a car. They are replaced, what, every 10000 kms or so? That belt is under tremendous amounts of torque, I think that a bicycle on the street will be fine.

Of course, this is the BFSSFG forum so everyone on here has legs like fire hydrants and rides 200kms a day so these things will break in no time....

Do you own a car?

There's drag from the pulleys, but far from what I would consider tremendous.

I don't think the belt drives on Harleys are stretching all that much. Seems the power coming out of those v-twins would be greater than anything a cyclist could throw at it!

Sign me up!!

I predict a vandalism trend of people cutting parked bikes' belts.

A big V-Twin Harley puts out far more torque than any human powered engine could and belt drive seems to hold up just fine.

Belt drive on a bicycle is not exactly Treks's original idea....

Is there a master link type thing on it somewhere? How do you remove them?

Unscrew the drops from the frame and you remove it.

the district is pretty sweet looking, trek did a really good job with that color scheme. the belt drive seems like a pretty sweet system too, and although trek wasnt the first to utilize the system it is good to see a big company into a different direction with their bikes. then again perhaps there's a reason that chains are what is still in use today. either way, interesting looking bike, anyone know what msrp will be?

I think Trek killed it with the design on this, although the 2 stripes is a little 'madidas.' Love the colors, swept back bar, orange bolts... just looks real decent.

Also, that's not a SS hub, it's internal shifting.

Cool design, excellent engineering on being able to move the ends to set tension, rather than moving the axle.

A good portion of cars with overhead cams use a drive belt. The one in my ford ranger is 10 years old with 85K miles on it. The reason they last and dont strecth is that imbedded inside the rubber is a fiberglass belt that is what really provides the strength, and prevents stretch.

now I don't know that they did that, but I suspect they did.

I think they had a few set up, notice on the one with the internal gear, there is a fender mounted. On the over all shots there is no fender. Also in this photo it is an entirely different drop out than the internal geared one.

Also note the different wheels.

Here they explain the differences: https://www.cyclelicio.us/
Trek District
The District, a flat bar singlespeed bike featuring the Gates belt drive system, will be available in October for around $900. According to Trek, this aggressive road bike inspired design" produces an edgy ride with color matched Bontrager Inform saddle, orange rims, accents on the stem face plate, and even constrasting colored water bottle cage bolts. The Gates carbon belt drive shaves 280 grams from this urban bike while producing a "ninja quiet ride" with no lubrication.

Trek Soho
Soho is another belt drive bike, which will retail for under $1000 in December. The existing 2008 Soho (chain drive) has an 8 speed Alfine hub. The 2009 model shows at Trek World included matching fenders and a minimal chainguard.
The Soho will be the geared one, the District with be the SS.

Meh.

Those dropouts (?) look sloppy and it's probably less forgiving with a less than perfect chain line.. er, belt line.

The most efficient way of transferring energy is with a chain. Matters less with bicycles I guess, but with motorcycles, it's huge.
