700x35c tire size, your tube should be sized the same. 700 would be your wheel diameter in mm and 35 is the width of the tire in mm. You can not use a larger width tube in a smaller width tire, but since the tube is in general terms just a balloon, your tire is what holds the air pressure so you would probably be OK with using a bit smaller diameter tube (like a 32mm tube.) My old bike was a mountain bike with 1.95 inch tires and I had I think 1.75 inch tubes in it. A coworker gave me a 28mm tube to use as a spare in my 32 mm tires on my new bike because he switched to a thinner tire.

Note, I don't have experience with this stuff as I am just buying as well, but here is what I've decided after research.

Everyone keeps saying to get the Topeak Road Morph G. It is $35 at Amazon. It is small enough to mount on the frame, has a hose to connect to the valve and has a little peg that folds out for you to hold with your foot to pump. A lot of the frame pumps connect directly to the valve with no hose and from what I read, it is first awkward to use and second, it is easy to push and pull the valve around possibly damaging the valve. I am hoping this will do for an every day pump as well for a little bit because my 2 month old floor foot pump that I picked up at Walmart and have hardly even used already broke.

Everything I have read about tire levers is these, Pedro levers. So, I have these in my cart at Amazon waiting for me to checkout. Seems like a lot of reviews and forum talk about the fact that they have a lot of leverage and are pretty unbreakable as well.

I've been looking at an under the saddle bag to carry the stuff and the Topeak Aero Wedge bag seems pretty popular. I don't have much of a budget though for everything so I thought maybe I could knock a few dollars down and have this BV USA bag in my Amazon cart. Would like to see if someone has an opinion on this.

Just now i see another bag that looks nice. Aviner Bigmouth seat bag. Anyone know anything about this bag?

Again, those are just what I've been researching. I don't have personal experience yet.
