Hi,

I built a Fl1 last year and got enough kilometers to share my opinion about this frame. (Excuse my poor English) My configuration is Fl1 56cm, Sram Force axs groupset, Avian Canary 130x420mm, Assioma pro rs2, Farsports C3 with Conti GP5000.
The contact with Sherry was really good, the configuration, payment, and shipping were simple and quick.
The quality of the frame is good, the bottom bracket and brake caliper areas have been machined and are absolutely ready for assembly. So building was really easy. I first tried a mechanical groupset, but the space around the bottom bracket is really tight, adjusting the front derailleur is not easy. I recommend an electronic groupset.
Riding is very comfortable, even on bad surfaces, climbing is fun. I've never had an aero bike, so I can't compare.
But I think it's not the stiffest frame. I was in the Swiss Alps and I have to say that descending is not very pleasant. I had big problems with speed wobbling, which started at 35-40 km/h and only stopped when you pressed your legs against the top tube. You have to actively descend with the frame and cannot just let it run.
Maybe it's my fault or the configuration is not good, but these are my experiences with the bike so far.
Has anyone else noticed the same thing and found a solution?
Nevertheless, I do not regret the purchase, it is a nice frame for the price. However, you can tell that the price difference to the big brands is not just due to marketing.
Regards and success for your built ups,
Stefan
