Re: LTWOO ER9 & ERX - Electronic groepsets

Can you explain what you with the jockey wheels?  If previously did I must have missed it. Looking for best operations.

LTwoo in-spec has a 32t max cassette size. Running an 11-34t cassette on bumpy terrain while in the smallest cog would result in occasional chain drops. Sometimes when trying to build up speed on the downhill, I find myself in the highest gear setting (small cog). Ltwoo provides an 11t upper and 12t narrow/wide lower jockey wheel. I swapped out the Ltwoo stock wheels for Ultegra 11t upper and 11t lower jockey wheels. By doing so I was able to slightly move the upper jockey wheel closer to the small cog, which gave more stability on bumpy roads. Also the Ultegra upper jockey wheel has taller teeth. I noticed it keeps the chain aligned better when doing multiple shifts at once. On the stock Ltwoo upper wheel there's a chance the chain can jump off the upper jockey wheel if doing multiple shifts at once. I don't really see a point using a lower narrow/wide 12t jockey wheel.
