AI Summary
Hello everyone, here is my go at it.
First time building a bike from scratch and obviously first time buying a frame direct from China.
Frame, fork & cockpit : Tantan FM301
Groupset : 105 di2 12v (without crankset and consumables)
Crankset : Rotor Aldhu with powermeter (from a previous bike)
Wheelset : DT Swiss 1400 48mm/62mm (spare)
Cheap jockey wheel from Ali
KMC chain1 - Overall pretty satisfied with the build although i did not get to try the bike on the road (recovering from knee surgery). I like how it looks which is already a good thing
2 - The package was delivered damaged but the frame was well protected.
3 - Seems like this bike was designed for a gravel groupset. The FD hanger was not compatible with 105 di2 for 52/36 rings (sitting too low). I had to modify the hanger to make it work.
I also went for a gravel crank axle with spacers to increase Q Factor and compensate for little to no clearance with the frame.Later update on 2025-03-06 by julienb
Hello Everyone I wanted to update you on the riding experience after an intense weekend of riding
Friday : solo endurance ride 130KM - 1350mD+ - 206w average for 30km/h with the Tantan
Saturday : Group ride 100k - 1000mD+ 203w average for 31 km/h with my Canyon Aeroad CFR
Sunday : Group ride 130k - 1000mD+ 181w average for 31km/h with the Tantan
Overall the Tantan does not hold me back and i expect to get the same speed for the same power.
Handling, cornering, feeling at high speed: 5/5
Stiffness: 5/5
Comfort 3.5/5 The rear end feels stiffer than my Canyon. It does not filter as much. I would expect maybe more compliance from an all road set up. Definitely needs larger tires with less pressures to bring more comfort.
Overall pretty happy with the ride. Remember that my i make the comparison with a Canyon Aeorad CFR which is proven to be a fantastic bike. I am thinking about maybe changing the seatpost as a lot of the compliance on the canyon comes from the seat post. I also want to get rid of the offset
