Marzocchi flies again with new Bomber DJ – a super burly, light weight dirt jump fork

Are those bombers?!

20×110 is the old 20mm standard, while the new 20mm Boost standard is also 20×110 but is not the same as it compensates for hub flanges and disc mount being 5mm (I think) further outboard. The axle width fits the same but a Boost wheel may have clearance issues and the disc will be in the wrong place. I imagine Marz went with the older standard to accommodate the 26″ wheels, likely to be using older equipment.

spaceracoon – i’m fairly certain the lower casting was from an older gen Fox 36 that was re-used (now that Fox owns Marz, and because tooling/molds for fork castings is very expensive; it didn’t make sense to create all new tooling for something like a DJ fork that won’t have huge sales volume) which was created prior to the introduction of 20mm boost.

spaceracoon – the lowers on the new Marz Z1 are 15mm boost and use a QR style thru axle (this DJ uses pinch bolts) so this can’t be the same; plus the arch on that is the more pronounced “M”. the closer i look at it, the more i’m certain it’s the same lowers Fox used on the 36 from 2015 through 2017. it uses the same 20mm to 15mm axle adapter sleeves and the placement of the brake hose guide is identical. the dropouts (pinch bolt style) are identical too (the new Marz Z1 lowers do not use pinch bolts). the contours on the arch are the same. i remember joking at the time because this pseudo M arch was released on the 2015 36 not long before the announcement that Fox acquired Marzocchi’s mtb division. should note here i still have a 2015 Fox 36 with these lowers.
