i did notice the additional weight on the front. for me, heavier fork, heavier wheel, heavier tire. monster trucking was definitely easier.
i went from a 2020 fox 36 factory 180mm 37mm offset to a 2021 fox 38 factory 170mm 44mm offset(and tested a 160mm) . i'll leave out the big differences between these two forks. im 5'4 and ride a size small.
i def noticed more wheel flop in the parking lot and while riding. really sharp turns are tougher. while cornering the wheel flop didn't bother me so much. i hit a bunch of PRs on trails with consecutive corners(not 90 degree corners). the bike gets pretty slacked out. i think the geo charts put the HA at 62.5 degrees with a 170mm 29er fork. 160mm travel kinda brings it back in line with the stock HA of 63.5.
bb height increases a touch which is helpful.
side note, on the flattest part of my garage, i measured my stock setup HA and it's 62.5 and not 63.5 like the stock geo chart.
overall it feels like you're in a laz-y-boy couch. very upright pedaling position. you def will want to lower the stem spacers(or overall stack height) to get more weight/grip on the front. i normally run 15-20mm of spacers under my stem with my stock setup, but with the mullet, i ran 5-10mm of spacers under the stem. same headset cover, stem, and handlebars.
if you are in the zone, and ON the front, it'll monster truck and ride awesome. sometimes i ride like **** and just dont feel connected with the bike, this is when it kinda sucks. but thats probably more MY problem than the mullet.
because the bike is slightly rotated more towards the rear, i did feel like i was bottoming out more and my saddle was hitting my rear tire during full compressions. this might be because i run a low stack height saddle, and my dropper is installed all the way in, to the hilt. so no dropper post sticking out of my seat tube aside from the dropper collar/seal. i have short legs, so i HAVE to have it this way or else i can't reach my pedals. also looks the best.
we've talked on the pinkbike forums before on the sb165 group.
i ended up selling my fox 38 29er fork and currently back on the stock fork. 29er made me so fast, i was hitting rocks so hard that one of them knicked my kashima and that really made my OCD go nuts. so i sold it. im debating on going back to the mullet setup. i was hoping fox would improve something for 2022, but it doesn't look like they changed anything. plus i was running a borrowed wheel from a friend and eventually needed to give that wheel back.
