I just picked up my Hydra right from the WW shop in Newton. Received a great tour of the facility and learned, first-hand. about the never ending supply chain and overall parts supply issues WW faces. It was great to meet Pushkar and see where it all happens.
The Hydra first impressions are it is FAST, suspension and brakes are excellent and it looks amazing (unrestricted/27.5" wheels, chain drive).
The Large frame just barely fits my 6' 3" height and I will need both bar risers and the longer seat post to get it right for me - so something to keep in mind when picking your frame size.
It's very early in terms of riding time but one immediate niggling issue is when on either fo the two smallest cogs, the chain feels like it catches and jerks a bit; almost like it is in between cogs. The chain doesn't jump cogs but feels like it wants to. This will happen immediately after coasting and then pedaling again but you don't have to be pedaling to experience this jerk/catch - just rolling along on throttle as well. Thinking it may just be an adjustment issue with the derailleur - we will see.
