Hey guys. I’m curious what is your view on expanders/compression plugs. Yishun provided one(see picture), but I’m unsure if it’s any good or enough, if I want to use spacers. What would you suggest?

The JH-10 looks absolutely sick, and advertised 950g is incredibly light for a frameset, and like others have said, it looks fast in all the right places--deep tubes, fairly narrow headset clean lines, shields the water bottles.

BUT as Patty and others have pointed out, the geometry is not great. 72.3 degree seat tube but no zero-setback option for the seat post? Not great. Narrowest bar is 380mm with a max stem length of 90mm? Not great. The 582mm stack for a 56 is wild to me--my Seka which is supposedly "endurance" geometry has a 571mm stack. I support it--it supports very new school "tall and long" bike fits that I like. But damn it's tall bike.

how much have you guys actually paid for ER9? I'm seeing 475 which imo is still not that good of a deal

I have ICAN Aero 50 and Elite SLT (not edge). The Elitewheels is a proven, well loved brand and Edge is a fantastic wheelset by all means if you read reviews. However between SLT and Aero 50, the Aero is simply better in the way it rolls and sound it makes. The SLT hubs are incredibly loud. And I guess Edge also has those loud hubs. Aero's are almost silent comparatively and I love it for that reason. They have also stayed true for the longest time compared to any other wheelset I have had.

Very light, accelerate reasonably well and keep up the speed exceedingly well. Don't think you will unhappy with either. From my experience, in future if I am to choose between ICAN and Elite I think I will go with ICAN.
