Helios A9X

So far, with a little over a hundred miles, this bike has been fantastic. I am very impressed with the Di2 shifting. I've never experienced any like electronic shifting before; it is fantastic. The disk brakes are all everyone makes them out to be. Great in all conditions and speeds. Only two real negative thoughts. Assembly instructions are practically non-existent. There is incomplete wiring instructions for the DYI assembler, like me. I had to to research on the shifter wiring. It is not hard to do, just would have been nice to have those instruction. Seat post to frame squeaks a lot. Some more investigating solved that issue too. This is a very enjoyable bike to ride. Frame is stiff, transmits torque efficiently, and yet, the bike frame does a great job absorbing vibrations. as a result you have a smooth and comfortable ride.

Despite a hiccup in tracking the shipment, I received the bike in less than a week. Very easy to put together and the bike was tuned perfectly. The bike itself is very comfortable and performed excellently
