I've got a 21 with 3 demountables and one pretty bad square felloe wheel. I thought I'd put a T hub in this Overland demountable wheel. Spokes felt tight, didn't look too bad so I thought I would tap them off the hub with a hammer. I've changed hubs like this before. Glad this one broke when it did. I wonder if those were the original spokes? I've knocked out plenty spokes that looked a lot worse that never just popped in two. I didn't hit it that hard.
