|Hook Bead Rims & Armadillos||drop-in|

|I just bought some Specialized Armadillos and they recommend a certain air pressure with hook bead rims. I'm not sure what this means. Does it mean they can't be used with non-hook beaded rims? How can I tell if I have hook bead rims?? My rims are some fairly old (I mean retro)Mistral clinchers made in England.
My question is can I use the Armadillos on these rims?

|Alright then. A hook bead rim has "hooks" to hold the tire bead on. With the tire off, take a look at the rim, and the tops should have an "L" shape, upside down, of course.
Without seeing the rims, I can almost certainly say they're hooked. The straight style pretty much disappeared as high-pressure clincher tires came to market. Older Schwinn cruisers still use straight-sided rims, but there you can't inflate over a certain pressure, or you risk blowing the tube after the bead slips off.
So, have a look, but I bet you're fine.
