When I get my head round it all, it’s really simple to understand.
The other 97% of the time it makes my head hurt, would love to know why shimano decided to bring out A/B spec.
B is cheaper to make, but still an exclusive design that no one else would tool up for to produce the parts and with B you can fit/replace/remove a shifter without removing the brake lever too.
I think the design job was given to the work experience gang who did good, but still cocked it up.
Hopefully someone said ” just tap a thread into the lever body” at some point but we will never know.
Instead of the simple thing, cut off a small piece of metal, or even in the first place, they redesign the whole lot to get more units shifted.
In the end it’s all about the ride, as long as you buy their gear.
