This is possible but does notably change the geometry. The change results in approximately 1° slacker head and seat tube angles, 20mm shorter reach and BB height 10mm closer to the ground.

A 2.5” Maxxis fits with appropriate room around it.

No, there are no ISCG mounts on the Rootdown [VI].

All our frames can work with +/-10mm of fork travel. To generalise the geometry change is around a 0.5° slacker head tube and seat tube angle for every 10mm added.

All geared hardtails run a standard boost chain line (52mm)

With a 52mm chainline (SRAM boost standard), the Rootdown [VI] can fit up to a 34-tooth chainring.

For context, most of us here are running a 30t, with a 10/52 cassette.

There is a serial number on the back of your fork arch, adding this to Rockshox Trailhead app along with your weight gives a good baseline setting.

Post mount brakes are a much more common standard these days, which means in most cases this negates the use of an adapter.

We were seeing a great deal of variation in diameter from BB manufacturers. This is very hard to account for with a press fit.

Threaded BB's (and threads in general) are much more standardised, which means less variance from one to another. Also, the action of tightening down the cup into the frame more easily accounts for variations in thread quality from different BB manufacturers.

We chase the BB threads on every frame, ensuring good fit with both OE and aftermarket bottom brackets.

It does, however the specific blend of steel we use (CR-MO) has very good corrosion resistant properties.

The Rootdown [VI] also has our ED coating inside and out which further helps protect it from the elements.

Nothing of note on this frame. Please let us know if you have tried to fit a more obscure component and faced issues.

Greasing you seat post prevents this issues, we strongly recommend re-greasing every 6 months at a minimum.

Not much! Here's what you need to do if we shipped your bike to you:

• Inflate tires to desired pressure. (Sealant is already installed)
• Install brake rotors, tightening bolts to 6.2Nm.
• Attach derailleur to frame, tightening to 9Nm making sure that the B-tension tab rests properly against the derailleur hanger stop.
• Grease headset bearings, install fork and handlebar, positioning the headset spacers above or below the stem according to rider fit.
• Align handlebar stem, preload headset and tighten stem pinch bolts to 8Nm.
• Install wheels, tighten axles.
• Install chain with quick link.
• Grease pedal threads and install pedals using pedal washers supplied.
• Adjust brakes, shifters, saddle position and height for personal preference.
• Set up suspension.
• Bed-in brakes. (Roll down a gentle gradient dragging one brake at a time. Avoid locking them up.)
• Go ride!

Note: If you had to Google "Nm", or you don't know which way to install your rotors, you should probably get a qualified mechanic to build your bike!

Here's what's been done:

• Chain length adjusted.
• Gears adjusted.
• Brakes set up and bled.
• Handlebar tightened to 6Nm.
• Grips tight on handlebar.
• Crankset tight, bottom bracket tight/adjusted.
• Saddle and seatpost tight.
• Seatpost greased *make sure to re-grease every 6 months!
• Tire sealant installed.
• Cassette tight.
