Stefan - Apples and Oranges...totally different bikes. You are comparing a Vado to a Creo. Did Specialized add a stock chain guide to the Vado to prevent inside chain drop? Not that I am aware of so expectedly, it must not be a problem.I cannot agree to that. My Vado has a 48T Praxis Wave Narrow-Wide chainring and an 11-46T cassette. No chain drop over more than a year
That could be the reason. My chains have always been properly aligned.
You state you have a “Praxis Wave Narrow/Wide. You are combining two different technologies into a single statement. Praxis Wave technology is not the same as narrow/wide. It’s teeth has the same profile but alternate in an inside/outside pattern relying on lateral force to retain the chain. Their website actually states:
- In very rough terrain, or just for pure security, we still recommend use of an upper guide
Tooth heights are the same. Tooth widths vary between standard (narrow) and wide.
Narrow/wide is alternating narrow and wider teeth. It relies on friction to keep the chain on.
I am not arguing one technology over another. I was simply stating what riders of the Creo, not the Vado, are experiencing and for some, by swapping Praxis Wave technology for a N/W variant technology, it has solved their chain drop issues.
Nevertheless, I’m not sure I understand what you agreeing and disagreeing to has any bearing on the facts. Specialized obviously agrees with it by adding the stock chain guide to the 2021 Creo models and their the ultimate authority.
For those of you who actually ride a Creo, and have been experiencing chain drops, if you have a model that does not come with the chain guide, and want to try it, the rumor is Specialized will eventually start selling it as a after market part. The purported SKU is S211200002 but a search of the Specialized US website yields no results. Maybe check with your dealer.
