First Look: Rose Root Miller

by
May 29, 2017

After getting a good look at the new Rose Bike range during the 2017 London Bike Show, we’ve been eager to get our hands one of the full suspension bikes since. Fin from Rose Bikes UK has followed through with the goods, having delivered a fresh Root Miller to Singletrack Towers for an upcoming Pennine Pasting™.

The Root Miller is the German brand’s 29in full suspension trail bike, with 140mm travel front and rear. It’s based on the same suspension platform as the 27.5in version, the Granite Chief, but adds in the wagon wheels for extra traction and speed on rougher terrain. Offering a bang-up package for the money thanks to its direct-to-consumer model, the ocean-blue Root Miller test bike is certainly appealing on paper. Before getting stuck into testing, we’re going to take you through some of the details of the bike here.

German brand Rose offers bikes direct-to-consumer via their website.

The trail is rough and challenging. You know that you can rely on your bike. Everything that gets under your 29-inch wheels suddenly seems small. Your ROOT MILLER quickly absorbs bumps and gives you full control. The trail is flowing, you feel like a surfer, you celebrate the profile of the track, you enjoy every corner, every drop. This bike is your fun bike – even more potent than before. For this we have upgraded the travel to 140 mm in front and rear, lengthened the top tube and slackened the head angle. In this way, we could further improve the bike’s downhill performance and increase riding pleasure. The new Boost standard and the option to ride 27,5 plus size tyres also promises a boost in performance. Even more possibilities, even more action – the ROOT MILLER offers you the full range” – Rose Bikes.

Up front is a 140mm travel Fox 34 fork with a 29in specific chassis.

Although Rose offers several models in the Root Miller series (there’s a 1, 2, 3, and 4), the customer has the ability to custom spec various upgrades at the point of purchase. So you can upgrade the suspension, wheels, drivetrain and cockpit as you wish. For our test bike, that means it has a fully custom spec, which is built around Fox Factory Series suspension with lovely gold Kashima highlights.

With 34mm diameter Kashima-coated stanchions, the 34 Float is a slippery-plush trail fork.

Spank wheels aren’t a particularly common OEM spec.

The Spank Oozy Trail 345 wheelset features wide alloy rims with a 30mm internal rim width, sealed cartridge bearing hubs, and a claimed weight of 2090g for the 29in set. They’re built for durability, and are ready to go tubeless with Spank’s Bead Bite technology that helps to decrease the chance of burping – of your tubeless tyres that is, we’re not sure they can control your own indigestion.

Boost hubs front and rear with 32x spokes per wheel in a traditional 3-cross lacing pattern.

Nicely wide alloy rims with Spank’s ‘Oohbah’ tubeless rim profile that promises greater strength.

The Spank Oozy Trail wheelset uses a 30mm internal rim width to keep up with the Jones’.

A conventional four-bar arrangement controls the 140mm of rear wheel travel.

The rear suspension design is a relatively straightforward four-bar arrangement. Using a horst link rear chainstay pivot, the four bar linkage sees a small alloy rocker up top that drives the base eyelet on the rear shock. Despite being void of any fancy acronyms or showy graphs on the website, the conventional arrangement promises a smooth, active suspension feel with less influence from chain torque and rear braking.

Welded seatstay brace.

To keep the rear end taut under load, Rose has welded in a brace between the upper seatstays, while adding in an alloy outer tube between the rocker link plates where the seatstays meet the rocker.

And there you go – a brief virtual tour of one of our latest test bikes from German brand Rose. What do you think of the Root Miller? Do you dig the colour? The frame design? The spec?

We’ll be getting down with testing very shortly, with our Lake District correspondent, James Vincent, giving this bike a solid going over on his local challenging and rocky singletrack. Stay tuned for the full review, and head to the Rose Bikes website for more info.
