Title: Frame that accepts higher volume tires?
Post by: sherpaxc on September 14, 2014, 06:42:40 PM

I was wondering what frame would accept a 2.4 Ardent in the back?  Anyone know?
Thanks!

I'm pretty sure my IP-057 frame will.  Although, it also depends on how wide your rim is, a wider rim will allow the tire to have a wider profile.  My 30mm wide carbon rims have space to spare with my Saguaro Geax 2.35" tires.

I've got Stan crests now, but was looking at getting some wider carbon rims.  So the wider rim gives it a wider profile, does that mean less clearance?  Sorry for my ignorance. This is a great site. The mtbr thread is way overwhelming and loads way too slow.

Yes, wider rim = wider profile on the tire = less clearance at the chain stays.  How wide are the rims you are looking at?

In another post I made some measurements of tire width on my rims, don't have the numbers handy, but no clearance issues on either my IP-057 or IP-036.

I can tell you that the IP-256SL is pretty full with a 2.25 Racing Ralph on a 30mm hookless rim.  There is perhaps a bit more room to fit a 2.35, but it would be very snug and your probably beat up the frame when mud and rocks tried to squeeze by.  With the 2.25 RaRa, there is about 0.25" between the outer tire tread lugs and the inner chain stay.

My IP-106 can fit a 2.4 Mission Vee (a pretty small-knobbed tired) on a 35mm rim.

I've got the same configuration.
I made some pictures of the space that's left.

What about downsizing to 27.5 in the 29er frame and using the Trailblazer 2.8?

I'm not convinced trailblazer will fit, that clearance is tight. And you have to mess with new wheels etc.
