Baum Cycle’s newest DBM titanium gravel bike is definitely a mountain bike, a drop bar mountain bike. Absolutely embracing the truth that fashionable journey gravel bikes are just about simply reworked old-school inflexible mountain bikes, Baum goes full MTB with their newest drop bar bike. In different phrases… correct fashionable large XC bike tire clearance, low gears to climb steep mountain grades, and a dropper to ship it off sick jumps… even within the drops!
Baum DBM titanium gravel bike is a drop bar mountain bike
Baum Cycles calls their newest DBM “a gravel bike with MTB DNA”. Founder and CEO, Darren Baum loves driving the inevitably steep native powerline tracks from Baum’s HQ southwest of Melbourne, Australia. However these steep climbs and downhills are additionally extra technically demanding than most gravel bikes can deal with, so he wished ever-wider tires to keep up grip and management.
“I usually trip within the Brisbane Ranges alongside McLean’s freeway. Whoever McLean was, he didn’t know what a freeway was. It’s acquired 20%+ pinches in it. I’ve wished a motorcycle to deal with that type of trip for a very long time…. We’ve been doing it for the final 20 years.”
His answer is 29″ x 2.25″ or 2.4″ mountain bike tires and a correct wide-range 1x MTB drivetrain with a UDH. And as a substitute of attempting to simply squeeze that into an present bike, Baum created the brand new DBM from the bottom up for max off-road functionality. He type of Frankensteined an XC rear finish onto a gravel entrance triangle, then tweaked the geometry to steadiness the dealing with of the larger tires.
“I did the working design drawings for this bike 8 years in the past – I truly designed it concurrently the Orbis [Baum’s disc brake road bike].”
“Plus-Dimension” Gravel Tires
Baum says light-weight XC race tires work greatest, and low-profile treads nonetheless really feel quick like a “plus-size” gravel tire. It’s as much as you ways large you need to go.
Baum will construct the DBM with commonplace 12x142mm rear spacing to present you max 2.25″ tire clearance. Or go for a Increase-spaced 12x148mm DBM and get 2.4″ clearance like most fashionable XC and even path bikes.
They created a brand new wider T47 backside bracket shell and 3D-printed chainstay yoke to set the chainstays and chainline wider for the larger tires. That does additionally imply you find yourself with MTB cranks as a substitute of street/gravel cranks. However there’s nonetheless room for as much as a 44T 1x chainring, so top-end pace remains to be there with a 10T cog out again and the bigger circumference of the larger MTB tires.
“Plus-Dimension” Gravel Geometry
“The DBM’s geometry is particularly designed to ship a road-oriented driving place, preferrred for grinding over lengthy distances. Subsequently, the DBM has extra backside bracket drop (~80 mm) than a MTB as a result of there’s not the identical want for impediment clearance. The pinnacle angle [69°] is nowhere close to as slack as a contemporary MTB both, however there’s a longer high tube, shorter stem, and wider handlebars to compensate for the additional entrance tyre grip.“
Tech particulars
Geometry is usually inventory in 6 sizes (XS-XXL). However even then, how Baum finishes off your body and general construct is solely as much as the customer. Kind of fork – inflexible or suspension, accent mounts, built-in routing, and way more are as much as your creativeness (and purse strings.)
