Pro-mance M7006 might be an option. (http://www.pro-mance.com/product-390-504-5255.html)

Anyone know what open frame this one is?

@carbonazza - the color was called purple chameleon.  Frame was painted by Tideace when I bought it.  They also had a greenish/blue chameleon paint job.

Here is my component list - I don't have the actual weight for all the parts.

Frame:  Tideace FM-M009 - 27.5" frame - painted - 1120g (as advertised - includes QR dropouts) - $291
Tideace supplied headset, seat clamp, rear thru-axle, carbon steerer compression plug - ~250g (forgot to weigh)
Seatpost: Tideace carbon - 400mm - ~210g - $25
Handlebar: Tideace carbon - 660mm - ~120g - $17
Fork#1: Tideace carbon ridgid 29" fork - painted - 515g (untrimmed.  TA and nut added 110g) - $96
Fork #2: Rockshox Reba 27.5" 100mm 15mm TA - 1660g (untrimmed.  includes TA) - $280

Forte Corsa stem - ~120g - $13
Wheels - WTB i25 second-hand, hand built - ~2200g (HEAVY!) - $180
Tires - Schwalbe Evo Snakeskin - Nobby Nick Front / Rocket Ron back ~1340g - ~$70 (for both)
Sella Italia Ldy Gel saddle - ~280g - $100 (Mom didn't like it.)
Specialized clamp-on grips - ~120g - Free! (door prize)
Generic composite pedals - ~350g - leftovers
Tubes 27.5 x 2.1 ~400g

From my spreadsheet that I just did, 9757grams calculated.  On the scale right now as ridden on the trails- 9.8kg (bathroom scales - my nice hanging scale drowned in a rainstorm.)

So - not exactly svelt - but almost 2lbs extra in the crappy wheelset.  That would put me under 20lbs with the rigid fork and under 22lbs with the Reba installed.

And for ~$1600 - she has a bike that can be run rigid for CX and front squish for MTB.  To buy an equivalent 26" bike, would be in for $2300 and wouldn't have the rigid fork and this bike is 27.5.

I'm happy - and more important the daughter is happy (second bike I built her and SHE LOVES that it is a "Daddy" brand without any letters all over it.)

Well got it finished.  She wanted to start riding before I had a suspension fork, so is riding it now with the rigid (which I bought for CX season.)

She likes it so much that now I have the Reba sitting on a shelf waiting for a moment when I can take the bike apart and trim the steerer tube down.

The Sprinkle Donut steerer tube cap and the purple nipples on the rims were a big hit.

No weight or cost data ATM as I was lazy on record keeping and the 27.5 wheels that are on there now are heavy AM wheels that I bought as spares for the 2 Kona Full Squish bikes that we have.  I have a set of 26" Crest hoops that are drilled 24H so I could lace them up triplet (16: and make a really light wheelset.  But she fits the 27.5 just fine and the Stans rims are white which won't work as well aesthetically (and its all about the looks at this point.)

I did go with a Praxis BB so I could run the Trailcraft cranks.  The bummer and delay with that option was the nut plate laid up in the bottom bracket shell extended too far into the hole to allow the outer sleeve for the Praxis bracket to go through.  About a 30min with a small grinder wheel on a mini dremel tool took that down with plenty of threads left on the nut plate and screw to hold the access cover on the bottom.

(And NO - I didn't send her out without any brake discs!  Snapped these pics before I got them installed and just haven't taken any pics of the complete/complete bike.)

My wife is hot for the Julianna Furtado carbon.  I don't want to take out a second mortgage for her next bike, so thinking of building Chiner #2 (first was a 27.5 HT for my 10 y.o. daughter - Tideace frame and rigid fork.)

Doesn't seem to be a lot of dedicated 27.5 FS frame options.  Anyone recommend one that has similar geo to the Furtado?

I don't think she really wants Plus size (east coast flowy trail recreational rider), so I think just using a 27.5+ frame would put the BB too low with non-plus tires.

So here is where I'm at:

9.5 year old daughter has been riding a Marin 13" frame 24" wheelset for about 18 months.  She hasn't REALLY outgrown it but the 24" wheels are really starting to impact her riding compared to her peers.  She raced CX on a 24" CX frame last year and wants to race again this year but on a MTB instead of a CX bike.

So - I would like to build her a new bike as light or lighter than my previous build on the Marin (~23lbs).  Have looked at the FM-M001 frame and it would certainly fit the bill but have also looked at a FM-M009 27.5 in 15" frame.  I have some 26" Crest hoops that I plan on using to build Triplet laced wheelset for her.

By my calculations - this would put the standover height at around 26-27" (1/3 way up top tube) with 26" wheels and closer to 28.5" with 650B.   Effective Top Tube length is 30mm longer (about an inch) so she would probably be a "little" more stretched out but probably manageable with short stem and zero offset post.

Here are her stats:
Height: 58" (147cm)
Sternal Notch: 47" (119cm)
Inseam (cycling): 28" (71cm)
Trunk: 17" (43cm)
Forearm: 10" (25cm)
Arm: 19" (48cm)
Thigh: 18" (46cm)
Lower leg: 19" (48cm)

I would expect she will grow 1-1.5" in the next year based on her growth curve and her older brother's heights (she has bee taller than both of them at every milestone and 14 y.o. is now 5'10")

Is it worth it to bother with a 650B frame in hopes of putting larger hoops on later? (Seems like this frame and 650B would easily get her to 5'2" without being to jammed up?)
Will 26" wheels on the 650B frame mess up the rideability considerably?
She is going into 4th grade - so she has 2 years before she starts riding on our NICA team. Am I fooling myself to think she could ride this bike (assuming built in the next 6 months) in the Spring of 2021?

Nothing can be transferred from the 24" and I will probably hand that down to one of the other neighborhood girls. 

I'm sort of using the TrailCraft Timber 1x top build as a benchmark.  With a lightweight aluminum frame and wheelset - they claim 21.75lbs for a 26" bike.  But I think I can build it for less than $2300 using Chinese Carbon, hand built wheels etc.

Hey BXCC

If you are still monitoring this thread, I have a question.

You mention putting 27.5 hoops on at some point.  Are the chainstays long enough on this frame to support 650B?  This is what I have been thinking of doing as well.  I have a couple of sets of Crest hoops in 26 - so was going to put my daughter on this frame and then grow her up to 650B. 

I had been looking at the 15.5 frames that are marketed as 650B but I thought it would be a bit tall for her for a while.
