Howdy!

I just started using a Magene P505 with this adapter (https://bdopcycling.com/product/bdop-track-adapter-110bcd144bcd-shimano-4-bolt/).  I only have one ride on it so far, so no real feedback yet, but I got the PM/crank for $200 used so it ended up being a nice deal, and it's the same PM I use on the road bike, so less chance for variation.

I've got about 500 miles on an AK105. I really enjoy it and have had no issues. I swapped a Magene p505 on and narrower handlebars. It did shift perfectly right out of the box. Seems to be good quality for the price. I have heard the lower end Sava models are fairly poor quality.

Not sure what current prices are, but 4 years ago the frameset would've been $760 USD for just frame/fork/shipping without tax.  I paid $1030 including handlebar, paint, spare derailleur hanger, paypal fee.

I do think this is a good do-it-all bike.  I used mine for both gravel and road for quite a while.  I picked up a road bike this year, and there's two main things I notice.  The stack of the road bike is lower so it's more aggressive, more aerodynamic position, but less comfortable.  The steering is also snappier on the road bike than the CFR707.  Before I started racing crits, I didn't care at all.  But it's nice having the quick steering for crit racing.  To be honest the only reason I bought a road bike is because I was switching between road and gravel wheelsets often, it was more for convenience and not for performance.

Dang, wish Balugoe had those a few months ago!  I got the ones with less flare, 34cm at the hoods and 37cm at the drops, and LOVE the hood position, but wish there was a bit more flare.

Got the Yoke in the mail last week, haven't done anything but measure so far, and don't plan on installing until putting some good miles on the Brain this year.

Brain shock + yoke, eye to eye = 255mm
Brain shock, travel = 49mm
Brain shock + yoke, at bottom out = 206mm

At bottom out, there's an 8mm gap from the seat stay bridge to the seat tube.  With potential for compressing bottom-out bumpers and frame/pivot/etc compliance, I wouldn't want to go much closer.

AliX yoke = 60mm
Recommended shocks = 200x51mm or 200x57mm

210 shock + AliX yoke, eye to eye = 261mm
51mm travel at bottom out = 210mm
57mm travel at bottom out = 203mm

I was using a measuring square, as parallel to the frame as I could tell, so it may not be the most accurate.  If my measurements were perfect, going to the 57mm shock would bring the seat stay clearance down from 8mm to ~5mm, but I'm sure there's some inaccuracy there.  I think it's at least close enough to say that a 210mm eye-to-eye shock will raise the rear end by ~10mm, the 51mm travel shock will bottom out a bit higher in travel than the Brain (but have slightly more travel), and the 57mm travel shock will bottom out a bit lower in travel than the Brain (and have ~15mm more travel).  I would assume the BikeYoke version keeps top-out height the same as the Brain, but the shorter shock option reduces travel, and the longer shock option matches factory travel.

Raising the rear end by ~10mm will also steepen the HA and STA, so could be a good candidate for a 110 or 120mm fork.
