Ti spindle Isis Bottom Bracket lasted a week.
How much travel is that bike? We used to build a pivotless rocker link bike that had 60mm but we used a trek fuel (before trek did) style rocker to eliminate the dropout pivot. That bike will flex at the dropout.
Just curious.
Just curious.
Standard travel is 1.7 on these... but the unique part about this one is that the shock will have a longer stroke and the stays will be preloaded... extending travel by a bit more than half inch. I'll probably run it super firm... let the ti soak up the vibrations and the shock deal with only the big stuff. The goal is to make a really fast, light, hard tail feeling bike that will eat the big bumps.
Have no idea what the hell I'm doing up... it's 1:30 and I rode with some super fit elite cross guys tonight... I feel beat, but eyes wont stay shut.

shut up
Brace yourself... The shortest distance between 2 points is a straight line
MAn I lvoed the Isis Ti BB's..... Those were friggin bullet proof. Lets just say some parts are great built in Ti, some are not
?????
so what's the latest on golgi's sh*t show?
I think he is still waiting for the frame so he can strip out the brake boss's and claim it as a manufacture fault
Sorry guys been on vacation so haven't been on the computer at all... Bike turned out real nice. Only kink on the build up... noticed a small bit of play in one of the swing links. Turned out to have been machined with some extra material at the contact point... Extra material removed... Problem solved.
Looks to have been built to spec. Just a hair over 23lbs without pedals. Will report on ride when I get a chance to put a few dozen miles on it.
Note: I'll trim that cable after I pick up a new barb. Also... Rear brake cable routing is funky. Shock needs to be removed inorder to route cable without detaching brake hose... Suckage.

I am interested in seeing a close up of the rear dropout.
Looks like an off the shelf "breezer" to me
If you remove the linkage, do the seatstays spring into a straighter line? Curious if they are preloaded since the dropout has no pivot and is obviously gusseted so it won't move.
I thought it was standard practice to build a pivotless frame at 50% travel. That way it will never see strain more than 50% of travel whether topped or bottomed out.
When the shock bolt is removed the seat stays look about the same... But the chainstays spring up about an an inch... Makes for an interesting time putting the shock bolt back in place.
I don't think it is preloaded to 50% though... More like 20%.
I'll post more photos later... They dropouts are indeed breezer style, like BYO posted, but the hanger is replaceable.
Put quite a few miles on the bike today. Rides well, very racy... Fast handling, fast climbing, accelerates quickly, very sharp feeling. I had a pretty fat tire of the rear... Got a buzz a couple of times in a hard rocky corner... Have dropped down to a 2.0... Lots of clearance now.
Here are a few more photos:

Nice looking frame!
Last bits are in, Middleburn crank, rings from HBC. Nothing more to do except ride.
Is that a simple strap?
Honestly not my cup of tea for a mountain bike, but nice job! 
Never heard of that... what are you talking about? The strap holding my tube to my saddle?
It was built to race XC. Light and fast.Honestly not my cup of tea for a mountain bike, but nice job!

That's a joke, right?
Nope, a very handy thing to have. I never use them to strap tubes to my seat but have found a million other uses. Not much different than any other generic strap other than the rubber strip which prevents it from sliding around.
Same thing... mine is a bit wider though, was originally for tying down the right leg of your pants for commuting. I keep a tube, 2 co2's and a small lever in there. I've seen some pro guys do the same with duct tape.
There are a few small complaints I have with the frame design. That is one of them. I also wish it had more tire clearance in the chain stay/BB area, its too tight for comfort on 2.2+. The other thing is that there is very little clearance between chain and the top of the chain stay when shifted to 32/11... it clears, but it's stupidly tight... if the stays had either a slight bend near the dropout or had been welded just a hair lower they could have doubled the clearance in that area.
The bike is a rocketship though and I now that I have it dialed in I'm very happy with the ride... so I'm trying not to focus on the small negatives.
there's a merlin frame on chainlove right now for $1200...
is that patented?
If you watch the Lynskey site "the loft" sometimes you'll see the 26ers in there for under $1k.
