Was hoping to see if there was a general consensus yet as to the durability of the 256 frame? The 057 has pretty much been put through it's paces enough over the past year or so without pics of cracked frames popping up (I actually can't recall seeing even one durability issue with the 057 - one of the attractive features of the frame imo) but seeing as how the 256 is newer, it hasn't quite proven itself.

That said, there are plenty of those frames being ridden around right now, and so far haven't seen any known issues with it either. Of course, some were/are cautious of the whole bottom bracket trap door thing.

Was hoping to here from anyone who has a 256 frame and has ridden for at least a few months or more in fairly difficult terrain.. Any issues? Trap door is a non-issue, I assume?

Honestly, there were about 3 complete builds with the IP-256SL up until about a week ago. A select few persons got an early production IP-256SL around May, but the vast majority who ordered only got them this month.  There aren't enough data points to draw any reliable conclusions at this point.  I'm very curious myself.

I would hope the IP-256 will be as bullet proof as my IP-057 has been but only time will tell.

I think the bottom door is a non issue.
It may help passing and maintain the shifter cable.

As I just finished building mine. Here is another potential worry.
The rear brake hose goes through the frame and is free to move in the tubes.

When I see how a cable can hurt a frame on the outside.
I'm wondering what will happen in the inside?

I rode yesterday, and some parts of the trail are quite rocky, and I could hear(at least I think) the house shocking inside the frame.

It's been a while since the last post here.  Does anyone have more input on this now??

I think no input is good news   

I have well over 600 miles on mine without issue. Same with the other two my coworkers built. Bikes have been great. 

There was a post back in August of a rider that broke his IP-256 at the seatpost/chainstay Y-junction shortly after getting the bike built.  Possibly just a flaw in the carbon layup on his frame, so far I've not read about any other people who have had issues.

2200 kms on mine. No issues 150lbs rider.
