Shimano knob chart

There are two knob sizes for Shimano reels, Shimano A and Shimano B. Most bait casting reels and spinning reels in the size of 1000-C5000 have Shimano A. Large conventional reels and large off-shore spinning reels in 3000-30000 have Shimano B. As you might have noticed, A and B are both used on 3000-5000 models, and you have to check the knob shaft dimensions to determine by removing knobs. It is known US Stella 3000 has B, but JP Stella 3000 has A.
