I talked to my bike shop and they don't have any extenders in stock but they said they come in different sizes like 18, 23, 28 mm. I found one on Amazon that's 20 mm. I asked the bike shop guy and he was saying I'd probably need to get a fitting to confirm which size I'd need. Would you all recommend a specific length for the extenders? I have no clue and am guessing maybe 23 mm is a good start? Any suggestions about that? Thanks.
Edit - almost all options on Amazon are 20mm so is that what is typical for extender length?
