Dinolfo Cycles has just released their first hardtail mountain bike. Like their gravel frame, the Dinolfo Hardtail is hand-fabricated from custom-butted 4130 steel tubing at their HQ in Wiesbaden, Germany. The brand decided to keep things classic and simple, opting to run all the common standards allowing the bike’s unique geometry to do all the talking.

There’s very little to know about the Dinolfo Hardtail, and that’s just how the brand wanted it; fast, functional and fuss-free. The frameset sees all the regular mountain bike standards, if such a thing exists; boost 148mm rear end spacing, a 44mm headtube, 180mm post mount brake and a 73mm threaded BSA bottom bracket.

The Dinolfo frame gets four bottle cage/accessory mounting points; two on the top of the downtube and two on the underside of top tube

The Dinolfo’s geometry is optimised around 29″ wheels and a 612mm axle-to-crown fork, or 140mm travel; the one picture here is a custom-made 140mm travel inverted fork from Intend. They do tell us the frame geometry can also work well with fork travel anywhere between 130mm and 150mm, however.

A 447mm rear-center length on the large frame gives the Dinolfo clearance for a 29″ x 2.5″ wide tire out back. Almost equally balanced front-to-rear, reach comes in a tad longer at 450mm. The head angle sits at 65° paired with a 74° seat tube angle. Though they make not look too dissimilar, the Dinolfo’s geometry is a little more conservative as compared to that of the mixed-wheel Starling Roost Hardtail we wrote about earlier this week.

“All the standards”
“Functional”

Not a rack mount in sight……

K. Cool.

@Dirt McGirt You see a lot of riders running racks on your local trails? I don’t think I’ve ever seen a single one, and just about every bikepacker I see nowdays is running bags that don’t need rack mounts. I think what you may be looking for is a totally different type of bike.

$2900 is a bit steep, even for a good looking custom steel frame.

I think the ability to mount a rack on a mountain bike is a necessary thing. Not for trail riding, obviously. And with 30 years in the bike biz, I know what bike I’m looking for. I have one. It’s a rad mountain bike with crap tons of mounts on it so I’m not limited to little bikepacking bags and simple trail riding.

Thanks for the input though.

What 140mm fork has a 600+ mm axle to crown length?!? My 160mm 29er forks are in the 572 range. Even a190mm travel Zeb is under 600mm.

They’ve connected that dimension to the wrong point. It should be 70mm above the BB height. Bear in mind this is unsagged too.

Only 3k for the 4130 version? I wonder what the titanium version will go for?
