I recently got a hold of a Thunderbolt from a fire sale and it came without a front wheelset. I borrowed the front tire of my 29er hardtail temporarily to get it up and running. I have yet to try the setup on our local trails but it got me thinking if I should go the B9er route. The thunderbolt has Ride-9 so I can probably adjust the HA from there whether to it steeper or slacker, depending on how the bike rides.
Would like to have some inputs before going forward on this.
