23 mm vs. 25 mm Continental Gator Hardshell tires

nice blog sky

If you can switch the tires for just any difference in cost then I’d get the 25’s especially for a cross country ride. According to an online spec sheet the 2007 ruby pro came with roubaix pro’s 23 on the front and 25 on the rear. If you liked the roubaix’s then the conti’s should feel close.
I use 23/25 on my road bike for a little more positive feedback and steering in front and a little more surface contact where the majority of my weight is on the back.

Personally I like a more supple tire like my 23/25 Vittoria’s, even with there shorter lifespan, for long road rides, climbing and descending so I’m not a fan of gatorskin/marathon/armadillo types except for commutes or heavy touring. Even on my bike for light touring I use 25/25 Vittoria’s though.....i rode that on the week ride across iowa with no problems Lots of good choices for tires.

J When I take the front wheel off, the Grand Prix tires don't clear the brake pads freely, I have to push the tire through them.

cantilever brakes ftw with really wide tires ....and yeah play with pressure on the 4000's. I'll do that on a clip seal road and that along with my sevens design to help eliminate vibrations it helps a lot. ...wondering if the 4000's might be a good tire for a coast to coast on a ruby?
