Is it for you?

Best suited to
Enduro riders who want Rail+ travel and power on an aluminium frame at a lower price than the carbon 9.8.
Standout strength
RockShox Lyrik fork and Super Deluxe shock on an Alpha Platinum Aluminum frame, for much less than the 9.8 Gen 5 carbon build.
The main compromise
Still a five figure price bracket bike that sits well above every other Trek model already listed on eBikeFinder.au.
