I bought a rear wheel to put on a SS build I'm doing for the student intern at work. Got this one with a blue anodized Shimano hub and it came with a sprocket, but I've never seen this contraption before: Seems to use a standard track sprocket, but it's too small (14t) and I'd like to replace it with something like 17t.
What's to use to remove it/ or the sprocket?
Chainwhip and lockring wrench, or a (special Shimano) 2-prong FW tool?
Who made it?
Thanks for any help!
