Took a nice easy first ride this afternoon.  Only 8 miles or so, some mild trail with a few rollers and under 12 inch drops.  Bike did well.  While teh geometry feels very similar to my previous frame, the 150/150 split is going to take some getting used to.  Even though its balanced, it doesnt feel evenly matched front and rear.  Some of it is mental, and some may require some air pressure, rebound and compression adjustments.  Anyway, the shock contact hasn't caused a catastrophic failure yet, so thats nice.

I may be crazy, but looking at the flip chip, do you have it set to the larger position? From the picture TanTan sent me, it looked like the flip supported 200 or 210.

I believe the pic of the 200/210 flip chip is from the FM08 frame, not the FM10. The FM10 flip chip is unlabeled.   The 200 is the max length shock that will fit, any longer and the seat stay arch will contact the seat tube.

DANGER DANGER DANGER!!!!!

If you have a 200mm shock, Hold off on riding this frame until this gets straightened out.   The nose of the shock rubs the seat stay arch at 3/4 to full compression.  Its broken through the paint and starting to show fibers.  And this was just from test rides.   Emailing them to see what they say.  Probably not a great idea to ride this frame as it is, at least not hard.  Well, crap.  This sucks.

Thanks. The tire has a good inch, or maybe 7/8 if I really jammed it into the bottom out bumper. But I'm running 27.5 plus tires, it would be a half inch closer with 29ers.  The only reason I worry about the spacing at 200mm is rebound over jumps or drops. I sure don't want it to make contact. I just hope that too out bumper doesn't have much give.

Shes all built up, but still needs dialing in.  Maybe a shakedown run tomorrow.  Most of the parts are obviously well used from my last frame.  The Manitou Magnum was stretched from 140 to 153mm travel.  Drivetrain is all new except for the crankset and a worn out absoluteblack oval that desperately needs replacement.   Have a Wheels-Mfg thread together BB to keep from developing any creaks.  Wheels are nextie i45 carbon hoops on sram 900 hubs.  Brakes are simano zee with 203/180 hope rotors.  All around solid bike.  Ive been riding a big split in travel (140/100) for so long, this feels really weird to me right now.   Let me know if you guys want any detailed / close up pics of any specific areas, and Ill snap a few tomorrow.

Going purely by the clearances I see in real life, I'm inclined to agree that 205 is probably a mistake.  The 200 is scary tight as it is.

No, max shock they say is 200 x 57    "190*50mm / 190*57mm / 200*50mm /200*57mm"

Look at the geometry chart, it shows 185-205.   Offset bushings probably wont fit since the shock nose is so close to the rear triangle.  And even if they did fit, 205 is a trunnion size, isn't it?  You could only put offset bushings on one side.

Clearance is RAZOR thin with a 210 shock and the flip chip in the 210 position. No room for error.

Ruh roh, sounds like my 205 is not going to work here. I may get creative, or just get another shock :(

Pics look great, frame looks beautiful. You're making me antsy for mine to get here! I'm in Boston by the way, not sure where on the east coast you are but if you're close, it'd be fun to compare frames to see how QC is from their factory.

Sorry, I misspoke before.  I have a 200x56 shock stuffed in there, and I'm not sure you can fit the 205.  I spent too much time in the Hightower Group Purchase thread and got my shocks confused.  The FM10 has the 200mm eye to eye. 

If you haven't ordered yet, I'm wondering if TanTan could simply drill the air can mounting holes up 5mm for you?  Or maybe I'm simply misjudging how much wiggle room there really is.  I mean, they did claim 185-205, right?  Next time I pull  the shock, Ill make a more conscious effort to see if you can squeeze that extra 5mm, but my initial gut reaction is that it probably wont fit.

I'm down on Wrong Island, so its a good 6 hour trip to boston.  I occasionally ride upstate NY, but never really in new england.  I do have a couple buddies that have houses in NH and are always offering me a chance to ride up there, but thats not necessarily close either.  But if I happen to be up your way, Ill shoot you a message.

Frame weight was 3185 with the shock installed.  Ill weigh the shock next time I pull it, but I assume its somewhere around 300g.

Couple more quick pics.  This is with a 200 x 56 shock installed.   I dont see how you could possibly squeeze a 205 or 210 length shock in there, I dont think it will fit.

First minor difficulty.  I couldn't pull one of the trunnion bolts out of the plastic shock brace they use for shipping.  It just spun and spun.  Had to drill through the other side bolt hole and tap it out with a long screwdriver.  Not a huge deal, but took a while.   If that's my only hurdle, Ill be very pleased.

As for the shock hardware, it comes with two piece hardware on the shaft side (stepped ala manitou style).  Then on the air chamber side, it has two spacers so you can use the standard 22mm hardware of your choosing.  You dont need need either the 54mm or 40mm hardware kits, though the 40 is probably better than what it comes with.  I may also go for a 22mm ABI roller bearing on the air can side.  But for now, this is working.   Clearance is RAZOR thin with a 200 shock and the flip chip in the 200 position. No room for error.  Probably only 2mm clearance before the arch hits the seat tube.  But a miss by a mm is as good as a kilometer, to paraphrase the saying from freedom units.

Also, the frame came with TWO axles.  Not quite sure why, they seem to be the same.

Moving along.

She's here. 

Frame was delivered by UPS at 5:33pm EST, and and as of 5:39 I'm writing this post.

The box arrived in the best condition Ive ever had a frame arrive in.  A good sign.  Well packaged with 1/8 foam and tape, but no cardboard.  Regardless, it doesnt look like it bounced around too much. 

And now the fun part.  The cable exits and entrance are indeed on the bottom bracket and into the chainstays.

The shock appears to be a trunnion mount......    AND a standard mount.   Once I fit my shock on Ill be able to confirm, but as far as I can tell, they've included a handy little adapter to allow us to use a standard shock in a trunnion mount.  Saves me the hassle of having to fabricate something myself.  Awesome.  Frame comes with pressed in cups for an integrated tapered headset, though the headset was not included.  It did come with a seatpost clamp and rear axle.  I ordered two spare derailleur hangers for a few bucks more, nice to see they remembered.

So thats that...  Ill post up more once I start swapping parts over and really dig in.

UPS says it's out for delivery.   Counting down the hours.   Who wants to place bets on whether I open up a tattered box of carbon splinters or not?

Sorry mate, us badgering you must only make it feel longer.
No, no worries at all.  Its arrived at the local UPS warehouse.  Hopefully being loaded onto a truck right now.  Ill post pics the moment the frame arrives.  Usually around 5pm EST if its gonna make it here today.

.... Still Waiting .....

UPS showed a status of *Held in Warehouse* for a few days, most likely stuck in customs and clearance.  There's movement again now.  Maybe it will arrive today.  Maybe it will arrive July 4.  Nobody knows.  Frame was ordered Feb 10.  Its been a long wait.
