Missing some teeth
 

Biking yesterday with my Vilano belt-drive 8 speed.
I had gone about 8 miles out when the belt drive started a small hesitation when pedaling. Looked at it closely and saw a few teeth missing.
Turned around and headed back...the further I went, the more it was skipping.
By the 8th mile back...it was hardly engaging at all.

Called Vilano and they are sending out two new belts asap. The second one will be a spare.

See the pic for how many teeth I lost. :)

How old was that thing?

About two years...but a lot of miles.
I think I might have had the tension set too high. If it was too low..it would have skipped earlier.

Wouldn't too high a tension be felt in resistance? IDK, I don't have a fancy bike. We used to run drive belts on enduro karts where the one speed clutch was on the axle. Not as much killer heat on an axle clutch. Ran them tight, but not banjo string tight. Tightness builds heat as well.

Then they deteriorate. I bet the sun had something to do with yours. Or, what do they call it, ozone and something called "double bonders?"

Looking closely at the belt...I can see how one missing tooth leads to the next one being gone also. Looks like they are glued on with a layer of plastic/rubber applied afterwards.

Maybe tension was too low...I don't know. When I put the new belt on...I might take it to my local bike shop to verify the tension.

The belts are $50 each...I don't want to mess up with the wrong tension.

By any chance, does the belt manufacturer have a plant in Arkansas?

It's a Gates belt. The printing on it says "CDrive TW Belt 8M1248"

I took another pic. As you can see...I can easily peel back the next tooth in line.
If I had gone another mile...they would have all been missing.

It’s sounds like you’ve had one hell of an interesting life Milt. And somehow you ended up here. I’m honored.

I thought the title might suggest a girlfriend.....
 

On more sober reflection, i realize i'm a bit apprehensive about my stepson's recent purchase of a 924S, (with a 944 engine/ timing belt & Balance shafts drive belts) - and no exprience with WET porsches.

Cheers,

Watched a few YouTube videos last night on setting the tension.
A couple vids recommended using the Gates app on a smartphone. You hold the phone near the belt and strum it. The frequency tells the app when the tension is correct.

Most of the videos remarked that it is better to have too little tension than too much tension.

Or if you're a real badass, you'll use a tuning fork!

That's crazy, app that determines belt tension based on frequency. Just don't hum while you're checking the belt!

I was thinking "that sounds like the kind of thing that you'd carry as a spare."

I thought this video was excellent for anyone leery of buying a belt-drive bike.
Everything he says...I agree with.

Hah!....I ordered two just for that reason. (I won't carry the spare...but it will avoid the week shipping)

Not easy to change the belt...on the road.
The bike frame...like mine...needs to have a 'breakaway point' to get the belt on or off. (it's a bolted joint to allow pass-thru)

One internal metal sprag (if that is the right word) per gear welded to the cables would have made that drive bulletproof.

They want to sell belts.

hahhaha..i'm hoping this was a joke, because it was good!!

you're riffing off the old joke, "whats the best pickup line in AK"?

"nice tooth!".

right? if i'm wrong..sorry. especially if youre down to a single tooth :D

This video is very interesting....and shows how complicated the hub drive is on a belt-bike.
The same hub that is on mine....but the cog on mine is driven by a belt...instead of a chain.

I understand that the toothbrush was invented in Arkansas...

^^^ If it wasn't...it would be called a teethbrush.

https://www.verywellhealth.com/what-is-mountain-dew-mouth-1059177
Mountain Dew mouth has been likened by dental professionals to the level of oral health seen in a dental condition known as meth mouth because the rate in which the decay progresses in users of methamphetamine and the effect on dentition is very similar

^^^ I only drink Diet Mt Dew.
I wonder how that stacks up?

You know how you can tell the tooth brush was invented in Arkansas?








Anywhere else they would have called it a teethbrush. Oops, missed Steve's post When I lived in Texas, we used the barefoot triangle as the reference, Porter Heights, New Caney and Splendora.

Placed the belt order at noon on Monday. Today at 10am USPS delivered two new ones from Elkton, Florida. :)
Took a half hour or more to put a new one on and adjust it. The breakaway, to get the new one into the frame, was super stiff making it the worst part.

Took it out for a few miles...silent and perfect.
