I'm looking to replace my Knolly carbon Warden with a long travel 29er. I already have an Evil Following v3, so looking for something around 150mm travel to complement. Among my top bike options are the SB150 and the Transition Sentinel v2. The SB150 was introduced mid 2018. Any idea how long Yeti goes before updating / replacing models? The SB150 geo numbers are still spot on and not dated, so hopefully they will keep it another few seasons.
