2021 Specialized Creo SL E5 Replacing Praxis with Wolf Tooth Chainring

I recently purchased a 2021 Specialized Crew SL E5 e-bike and I read about many stories in a Facebook forum that the Praxis chainring can be faulty. In many cases, a cyclist rides a bumpy road and the chain can pop off the chainring. The recommended solution is to replace the chainring with an aftermarket version. In this case, I replaced my Praxis chainring with the Wolf Tooth 110 BCD, 48T Chainring. This video shows how to replace it.

Wolf tooth chain ring going well. I didn’t wait for a chain drop to change it. There are enough discussions in the facebook creo group that hint it may drop eventually. I wanted to avoid it. I didn’t need to use spacers and I didn’t need to modify the chain itself- reused the same length.

hello, I have exactly the same problem as you with my Turbo Creo SL, how did it go with the modification? thanks in advance

highly recommended, its smoother and has never dropped. WHY the praxis is designed that way is just wrong.

[@jeffpetrinitz2012]

The blue stuff on the Bolts is loctite. It prevents the bolts from loosening up with vibration. You don’t want your chainring falling off while riding. I also use loctite on my bolts for my shoe cleats and other bolts that I don’t want to loosening up over time like my handle bar bolts. What torque setting did you use?

@ucberk599 Looks good! After a few weeks how is your wolf tooth chain ring going? Does the chain align well when in the lower gears (worse/better) also have you had any dropped chain incidents?

[@rivergladesgardenrailroad8834]

it's perfect and after 2 years NO problems...

[@jimgoldman2316]

I had exactly this issue on bumpy rides. My bike shop changed the chainring, but seems ridiculous to have to pay for this if it is an obvious issue with a new expensive bike

How do you remove the bolt/add the bolt that’s hidden behind the crank arm?

[@ucberk599]

You use a bike torque wrench to unloosen the bolts from the front and screw in the new bolts.

[@Rookie2Racer]

One of the bolts isn’t hidden behind the crank arm?

[@grandimperialpoobah]

I'm having the same chain drop problem, especially when I'm close to the large gear in the rear. Can you let us know which torque wrench you're using (brand and model)?

best thing i did for sure...
