Thanks for the replies. I’ve attached some photos (the bike still needs to be cleaned as it was only wiped down) but in regards to the brakes I couldn’t find a model and only see the Shimano. The bike is a 2002 Cannondale RT1000. The bike is setup so that both brakes are applied with 1 lever because the captain we bought the bike from was missing a hand and therefore couldn’t apply the brakes with 2 levers. I didn’t/don’t know how to change it. I’ve tried to attach a picture of the device that brings them together but the mount for our handlebar bag is kind of in the way (it can also be seen that I misspoke when I said the right was missing the left is the lever that is missing). The left side basically is missing the silver level and the front derailleur level is the switch that you see so he could still shift the bike. In regards to the rims not sure if the Mavic sticker gives you information about the rims but I couldn’t find anything else that indicates a brand or model other than the tire.

In regards to the pads wearing down in 1 ride they weren’t new for the race and we have ridding about 1000 miles on the bike and not sure when they were replaced by the previous owner. We obviously should have changed them sooner. It was DANGEROUS. Neither of us really owned a bike other than when we were in grade school (we’re still in our 20’s now) so learning as we go what to do. When we replaced the pads at the REI we threw the old pads and holder away so not sure what brand they were. They were all pretty evenly worn (except the one of the rear pads was significantly more on the rear of the pad). The pads we put on are Avid Rim Wrangler 2 Brake Pads Powered by SRAM (basically what they had at REI). The pads after the 70 miles that we rode on them in the rain look a bit like they melted and when I touched them today pretty large pieces flaked off so I’ll probably replace them again.

Last I included a picture of what I assume is the threaded rear hub.
