have you tried, 2.3? That's generally about the max I've used. If you're running them at low psi, I doubt you can fit anything much bigger than that.

 

Thanks. This is the biggest I've tried. Seems 2.3 would be the next logical step now that you mention it. I appreciate the suggestion.

 

I ran some 2.2" tires (WTB's) on my wifes old MB-5 and they slightly buzzed the frame, but once worn in they worked fine. It really depends on the volume. I tried running 2.2 conti trail kings on my vintage 80's Marin and I was only able to fit them in back. They buzzed the fork a bit too much in the front.

 

Thanks. It looks like I might have to go through trial and error. I'd like to think I could get a 2.3 in there but it might depend on the tire.

 

I've been able to fit old 2.35 Z-Max tires on my Logic fork, so you should be able to do the same.

 

Thanks. What year range tire would you say?

Nice to see another Ritchey product!

 

I have 2 early 90's mb-4 and mb-3, forks not bad for clearance (not ritchey), frame is tight with 2.2 geax saguaro, new tire fuzz rubs chainstay. I actually scrapped the mb-3 for my next build due to tire clearance, my rock hopper has much more room.

 

Thanks Shane. Glad to hear you own more than 1 Bridgestone!

I've actually decided to put slicks back on my MB-2 because I just picked up my first full-sus - a 2009 Cannondale Rize 4. I did take videos of me on one last ride in the woods on my MB-2. I figured it was a good idea because it is a classic bike and has served me well since 1991.

Thanks for your tire input. Good luck on your next build.
