    A day of lessons for the unprepared cyclist!

    Today I was all set for a 65 mile ride in the morning. All was set, my bottles of water were loaded, I had enough food. I hit the road. About 15km in I notice that the rear tyre is going flat...

    "not to worry" I think "I have a pump, a spare, a repair kit, AND there is a gas station over there."

    Turns out that the spare tube was from my old bike and the valve wouldn't fit the new wheel. The pump is a small frame variety that takes forever to pump anything up. The repair kit dated back about 6 years so the vulcanizing glue was shot, AND because it was my new bike it was using the wrong sort of valve for any of the various air pressure gadgets at the gas station to be of any use.

    Thus I walked back 10km (seemed to take forever!) to where there was a cycle track side vendor who happened to have tubes and picked up 2 new tubes, and some new glue/patches for my repair kit. It wasn't the century I wanted to ride, but it certainly was eventful! I also learned that walking using different muscles. I really must see if there is some kind of car valve to bike valve adapter I can throw in my bag. Plenty of compressors along my route, but they are all useless as is.

    A presta to shrader adapter is most likely what you'd want. Just be careful using an air compressor, especially with higher pressure road tires.

    You are not the first person to learn those lessons, nor will you be the last. I did the same thing 15 years ago except my tubes were dry rotted, patches were dry and the guy who stopped to help me had the same dry rot and dry patches. Go figure!

    I try to rotate them more frequently now.

    So the presta to schrader valve adapters mentioned are cheap and a good thing to keep with you on a ride. Good thing is they are cheap I paid 1.50 for each (bought 2) at REI, and since it was REI I know I overpaid. One thing to keep in mind is that they are tricky to use with a gas station air pump and the pressure gauge on the air pump is hard to get a good reading on. SO its probably better to under fill the tube slightly rather than trying to get it spot on.

    I'm guessing the old bike was a schrader and the new bike presta. A presta to schrader adaptor would not be of any assistance in this case.

    Been there and done that. Hated it. But good lessons were learned and same thing with you.

    OP picked up two spare tubes during the ride and said "I really must see if there is some kind of car valve to bike valve adapter I can throw in my bag. Plenty of compressors along my route, but they are all useless as is.", so actually a presta to schrader adaptor could have been of assistance.

    I don't use them, but most bike shops in the US have them for about $1. Just make sure to try it out before relying on it for a repairing a flat. Some of them can be finicky and won't depress the center pin on the schrader chuck making them useless at a gas station.

    His old bike had schrader (tubes he had in his seat pack), new bike is presta. The presta to shrader would not have worked in this case. Not to mention a schrader will not fit through a presta rim hole.

    His statement is saying he now has presta (picked up new tubes) and needs the shrader to use the gas station pumps with new tubes. So it will be of assistance on future rides but not the situation in the OP.

    Yeah, I got all the that and the fact that the glue had dried up in his patch kit as well. He said he then had to walk back 10km and picked up two new tubes (presta?) and glue/patches. That's when it may have been of assistance. Oh well, it's all air in the innertube now, so it doesn't really matter.

    Reminds me though to check how old some of my patch kits are.....

    Haha! Got it now, I was thinking of the first part of the OP only. I think the 71 miler today sucked some oxygen from my brain

    I learned this early on. I don't have anyone to come pick me up, so instead of being a roadie with a little tiny seatbag. I carry a rather large seat bag with tubes spare chain linkage CO2's etc. etc. Spare pump etc etc

    You know the even more foolish thing? Having never seen such an adapter (which must of come with the patch kit) I HAD ONE ALL ALONG! I looked at it when I removed the tube, thought "what an odd thing." and threw it back into the bag. Went to the bike shop to switch out the tyres on my mtb to something a bit more road worthy and saw that I already had one. I didn't have to walk the WHOLE way after all...

    I'm usually a mile away when I realize I forgot something, like tire irons or my cellphone. I've learned to go back and get what you forgot, your mind will rest easier.
