Tubes....
 

First time posting here. I picked up a Trek 7.2FX about a 2 months ago. I've been riding about 50mi-70mi a week and really enjoying it. I have the stock 700 x 35 tires that came on it right now. I am looking to get the Panaracer T-Serv 700 x 28 . I was just about to order them (or something else if anyone cares to recommend something) when I got to thinking about what tubes would be appropriate. I usually ride in the middle of the rode through my neighborhood when I have to ride at night (no traffic). But I really try and ride a paved levee near my house. I ride 1.5mi to the levee on city roads (rocks and debris on side the shoulder etc.) I haven't had any punctures with the stock tires I have now. I'm really looking for less rolling resistance and to increase the distance on my rides. I'm also 140lbs if that matters. Thanks

I use 700 X 28-35 tubes in 28 tires.

Yeah and just pick up the Bontrager tubes at your LBS. Reasonably priced and work well.

Have you taken out and looked at you standard tubes because they might be for 35 to 40c. You should take one out and look.

I haven't looked at the tubes yet. I thought there might be a difference in the tubes since I seen several choices. I'll pick some up at the LBS. Thanks
