Gates belts for XC?

So who has used the gates belts on the cross country. I have 30000 miles on my stock belt, it still looks good but thought about replacing it this spring.

Okay, just want to share a little experience plus New Insights in regards to inspecting/replacing the Victory Drive Belt after mine suddenly just snapped and I got rear ended by another Biker (Yes $$) at just a little over 90k in 2017.
I had literally just carefully VISUALLY inspected my entire Original Drive Belt during another service and it showed no cracking, discoloration, chipped teeth or other unusual wear. So Yes, I was shocked and Pissed when it snapped far from home on a favorite Charity Poker run. Then I was even more pissed at myself later when I realized my ignorance in something I should have known being in the Automotive Parts field.

While belts are cleaner, lighter, cheaper, smoother, quieter and require less maintenance or adjustment than chains, they are made of Kevlar and carbon fiber and just like Automotive Timing Belts they suffer internal material fatigue over time and use. So while they look visually great, internally they become stiffer and more prone to sudden breakage. Not cracking in most cases as most mechanics that have repaired cars with snapped timing belts, they just suddenly snap clean.

I suddenly remembered this when I picked up the broken Victory Drive Belt and compared it to the much more flexible Replacement Victory Drive Belt. Night and Day in how flexible it was.

So Moral of the Story, besides visually inspecting your High Mileage Drive Belt, you need to remove it and check how flexible it still is compared to a New Drive Belt. Remember just because she’s pretty, doesn’t mean she’s safe. 😉

How was the tension and tracking when you did that inspection?

It was right on, I had just checked as part of my belt inspection. Early on years ago after having my rear tire replaced and getting belt squeal, I learned how to properly adjust and align my drive belt correctly myself. So the belt looked perfect and was set correctly.

Well until it just snapped as I pulled away from a stoplight at the head of a pack of bikes.

So the "reported" avg life of one of these belts is around 80K miles. I suppose each has to decide just how far he's willing to gamble, but I'm sort of, change at 80 (if it holds that long) and be very happy to have gotten that far with it. They will break. Just when?
I would agree.

About 80k you got your monies worth and still have a pretty confident reliability that it won't likely fail in the middle of nowhere. If you keep pretty local, then you can stretch your luck as you desire, but if your on a few hundred or more miles ride away from home it can be a much worse day.

I imagine that damage was done by the other bike, not the belt?
Yep, a Road King was pulling out right behind me and more focused on the rest of the intersection plus another bike alongside him at the light change. Took only a second too long to realize I was suddenly not continuing my pull away from the stop, he clipped me as he tried to swerve away from me and plus clear of the pack behind him also pulling out. Not his fault, he prevented a worse situation by swerving verses stopping and BLEEP Just Happens.

I changed mine at 70k miles. After I got the original one off and inspected it, I wish I had left it on there. I compared it to the new one in all ways possible. Absolutely no difference. Even the print was still clear. I went ahead and put the new one on since I had the bike all apart. But I feel like it was a waste of time and money. I believe I could still be running the original belt at 104k miles.
Just wondering, if you still have it, have you compared how flexible it still is compared to a new one? Like I said in my post/experience, at 90k it still looked perfect after my recent inspection, but I then realized how stiff it was compared to the new belt. Wondering if at 70k if you can feel a difference in the stiffness?
