The race is on to get this light climbing bike built up before Tour das Hugel (TdH) this year.
TdH is an “unofficial” bicycle ride that takes place every year down in Austin, Texas which consists of ~110ish miles ~12,000 feet of elevation.
After participating for the first time in 2021 I decided to make the punishment that is TdH a permanent event on my cycling calendar. I usually just slap some road tires on my gravel bike and give it my best shot. This year is going to be different, this year I am taking a dedicated road/climb bike. Assuming I can get it built before November 11th.
The core of this build is a size 56cm Flybike Asia FM906-D. The rest is going to be a cobble of parts that have been sitting in my bins for a few years, shy of a few things I don’t have. I just ordered the frame from Flybike which has a production time of 2 weeks and I don’t know how much time to ship.

I find a interesting result. This 56cm frame have contradict parameter between stack and head tube length. If its stack is 570, head tube length should be 170 instead of 155; If its head tube length is 155, stack should be 557 instead of 570. Calculated by bikegeocalc.
