Would be a huge saving to just buy a 29er front wheel. Any idea if this is a good idea with this particular frame? Was thinking 150 or maybe even 140 fork to offset some effect of the mullet setup since this bike is already super slack. I was surprised to hear you are trying to slacken it even more. I would like to run it mullet without making the bike slacker than it already is. I haven't really looked into the details yet.I've attached the geo change just by over-forking to a 160mm Lyrik. Will calculate potential mullet numbers tomorrow after work.Using my elementary math knowledge, the resulting geo of a mullet build with a 160mm fork would approximately be:• Fork Height: 571 mm (RS Lyrik 29)• Head Angle: 64.25• Seat Angle: 75.75• Wheelbase: 1203.3 mm• Eff. Top Tube: 593 mm• BB Height: 341.1 mm• Chainstay length: same• Headtube Height: same• Reach: -1.7 mm• Stack: +10.1 mmAssumptions:• Diameter difference between 27.5 and 29 in. wheels is at 38mm• Tires to be used are exactly the same model, just different wheel size• No flip chips or anglesets or offset bearings used• Mullet defined as the 29 wheel being in the front and the 27.5 wheel in the back (duh)Guys with engineering backgrounds may want to chime in and correct the above.

Will share as it comes along.
