Turbo Creo SL Expert Evo/Road Info.

I have just discovered Pathfinder Pro being a perfect gravel tyre. One of the fastest rolling, very compliant and puncture resistant. Make no mistake. Read the reviews. I've just installed and ridden these tyres and am in love.
 
Ok, so my chain keeps falling off even with the clutch engaged. I micro-adjusted the rear derailleur 2 clicks to the left and all seems well now. I have Di2, btw.

I'll have to test it on my next ride. Did a 55 miler today with a mix of gravel and tarmac. The gravel part was a little technical but the pathfinder pro tires and front shock performed well. I'm impressed with this bike.

I finally ordered the part below to keep the chain where it belongs. I did not order from that site but it was a quick find this morning.

Garbaruk Narrow Wide chainring. This has taller teeth than Praxis and I have never dropped a chain. Half the weight of the Praxis one to.

Does it also require aligning the chain plates to the tooth position like the Wave Tech version? But the taller teeth work better overall?

Yes it does. The whole idea of the Narrow-Wide pattern is one of chainring teeth is wide (you need to look at the ring from the top), and the next tooth is narrow. Of course, you place the outer chain link on the Wide tooth. (It is important to look at the chainring from the top! The teeth look confusing as seen from the side).

I would love to install this but I fear it may take more skill than I currently have...lol...

It is about one of the easiest mods to be done :) Yes, it seemed scary to me when I was doing that for the first time. Needless to say, I am a technical anti-talent, and cannot replace the tyre myself for instance :)
 
I can't use the same bolts currently on the bike?
You probably have a Praxis ring, which uses threaded bolts. I have no experience with road chainrings but the third-party MTB ones are not threaded but use a nut, which makes the matters slightly complicated. (All Specialized e-bikes except Creo use MTB Praxis chainrings).

the praxis chainring has threads in it, so they take one bolt from the outside through the crank spider and into the chainring. the garbaruk and wolf tooth are smooth holes, so you need a male and female bolt (a sex bolt, yes, actually called that!) to make the connection.

it really is very easy.

here are the wolf tooth bolts


and the chainrings

 
… (All Specialized e-bikes except Creo use MTB Praxis chainrings).

actually, they’ve branched out quite a bit. vado sl 5 now has an SRAM x-sync ring. some como are up in the 48t range, not really an MTB ring. not sure if the specs are always correct but a bunch also aren’t 110 BCD! specialized always specializing things 😂😂

104 BCD, 4 unthreaded holes is the MTB style even if a classical MTB ring ends at 38T :) Other brands making mid-motor commuter ebikes also use bigger 104 BCD rings.

There's something Mark I want ask you about. What bolts are used for the 110 BCD 5-hole rings? Are the bolts threaded or use a nut? Is there a kind of industry standard there? I'm asking because there are many different things in road bikes!

the stock praxis ones are threaded, but the replacement wolftooth/garbaruk are smooth holes for a sex bolt setup as linked above. the system is the same concept as the vado SL but it is 5 x 110, presumably inherited from larger diameter rings? on a traditional 2x/3x non-mid drive road bike it works a bit differently to attach both rings, but also not threaded, at least shimano. i think the threaded praxis ebike chainrings are somewhat unique to ebikes. not sure.

Thank you! (I missed your earlier post). I can see the road-bike bolts are different from the MTB ones. And I would say Specialized have been using the Praxis rings because threaded bolts are only accessed from the outside, while using a nut requires that you work in the tight space between the ring and the motor to insert and secure the nut.
