Here is an easy one, can anyone tell me the chain specs for a Paso 750? I am looking for pitch and links. Thoughts on roller,o ring, x ring???

Well, not as easy as you might think....

According to my service manual, Paso's up to serial number 750130 came stock with a Regina O-ring chain DA-OR136, 3/8" x 5/8". Using an online conversion I see that this is a 530 chain.

Serial numbers 750131 and up came stock with a Regina O-ring chain DA-OR135, 1/4" x 5/8". This shows to be a 520 chain.

So it would appear that the very earliest Paso's came with a 530 chain. Mine is a 520, as I believe most are.

My Paso has 108 links. But you will want to cut your chain to fit. For example, I believe mine has a 41 tooth rear sprocket. If you're only running a 38 rear, you'll probably want 106 pins.

The easiest way for you to do this would be to go look at what's currently on your bike, as far as size and length. The 520 or 530 should be stamped on the side of every other link on your chain. As for length, just count the number of pins, using a paint marker to mark the starting point.

I run the DID 520ERV3 X ring chain on my Paso, but they're rediculously expensive, like $180. Any decent O ring chain can deal with the Paso's power output just fine.

I prefer riveted links, having seen the results of a clip-style master link coming apart. But the tools aren't cheap.

Thanks for the info. I checked mine, although there were no number on links, a quick caliper on the rear sprocket revealed .25 and not .375 thickness.

I ordered a D.I.D 520 VM GOLD X-RING Chain: 108 Links. Although still more expensive than a roller, I thought it was not a bad deal at 107.00 delivered.

Also got breaker and rivet tool on the way. I should be set up for any chain issues in the future.
