Or you’re doing a conversion on a frame that wasn’t designed specifically for the tires you want to run? maybe it’s a road frame with very short stays designed for the use of very skinny tires, maybe has no dimples on the inside of the stays? Petty common for 70s era road frames, which are very popular choices for conversion. You could easily enough say, use a different frame, but none the less, there are in fact reasons why you could have little room for adjustment and it’s not a ‘frame designed by idiots’. But you’re welcome to your foolish opinion, I guess.

Not something most would be willing to do, and a lot of bike shops won’t do it for liability reasons. I don’t need to do that, nor am I offering such advice to do so. My point was there are in fact legitimate reasons why the full length of a dropout may not be useable. As far as wabi frames is concerned, I have no opinion, because I don’t own one.

The other is an ancient road bike with 1970s Campy dropouts. I have it set up to do roughly what I am suggesting for you, but with 3 gear inch possibilities and fast gear changes. 2 minutes at hill tops and bottoms. 3 chainrings. 2 cogs on one side of the hub (21 and 17) and the usual one on the other. Each cog lines up with its respective chainring. The three gears can be 38-21 = 49", 44-17 =70" and 46-14 = 96". (59, 60 and 61 total teeth works out nicely.) (I don't recommend doing this unless you have a machine shop at you disposal and/or engineering/CAD skills and/or most of a grand to burn, but done right it is really fun!)

In this case, not owning one, means I know nothing about it, as I have no interest in knowing anything about wabi beyond what I can glean from others. Therefore it’s probably best to not speak from a point of ignorance. What you choose to do is entirely your decision. No prerequisite required, so I’m not sure how you arrived at that opinion. I just try to avoid talking out of my arse as often as possible. I don’t always manage that, but I at least try.

Nah mate, that smiley can be read a number of ways. Besides, if your post wasn’t serious to any degree, why bother wasting the time, when it could be misunderstood. Seems rather pointless, but you do.
