I have been riding a Slate Ultegra (size M, i'm 1m72) for a year and a half now.
I really enjoy this bike, but it requires some mods.
First mod : tires. Stock tires won't endure real gravel roads or singletracks. Moslty pavement only... I have a couple of options : WTB horizon for versatile terrain, Surly Knard 41c for dirt only (terrible on pavement) , Schwalbe G-on 38 and Panaracer pari-moto 38 for road oriented loops.
You might want to go with WTB resolute, that i've not tested but look really interresseting.
Second mod : gears. The ultegra comes with a road specific gearing (36x52, 11-28), which is nearly impossible to sustain where i live (pretty much mountains all around). I'm running a 1x11 solution : MTB cassette with Roadlink, Garbaruk chainring in 38t. So basically i have 38t - 11-40. I can climb everywhere now...
Third mod : handlebars... Cannondale stock bars are quite good and light. But i've tried Ritchey Venturemax bars for a week-end of bike-packing, and it was really fun. As i'm more into "race mode" now, i've put a classic carbon bars i had for years.
All in all, this bike a truly versatile. Can go much farther into singletrack that my previous gravel (pinnacle arkose). Very fun to ride, thanks to the oliver fork.
Weight wise, mine is 9kg with this setup bellow. with light tires such as Panaracer pari-moto, it's 8.5kg.
One important thing : check the rims. Cannondale has called back all the original slate rims (hookless) and switched them to Mavic rims, because there was some tire pop-outs when ran tubeless. I 've kept the original however, and never had any trouble... the pressure i use is quite low (28/30 psi)
hope it helps !!!
