Bronson 150mm VPP Travel - 27.5"

MBR Test Winner
MBR 10/10

Living Up To The Hype

When we introduced Bronson, it took the market by storm, redefining what people expected from a 150mm trail bike. Equally at home in the Trans-Provence as it was on The Ridge, updating and improving it was going to be no small feat.

The most visible upgrade is the completely new VPP® link arrangement.  The lower link tucks neatly above the bottom bracket, fully-recessed and protected from impacts.  Meanwhile the box-section upper link now mounts cleanly to the top tube and enhances lateral stiffness as a result. Shock rate’s been refined in the process too, delivering greater small bump sensitivity and a more progressive mid-stroke.

Geometry has also evolved subtly to meet demand from riders for a bike of this ilk.  The seat tube angle’s been steepened, placing the rider right above the cranks and perfectly in position to lay down the power. Meanwhile a one-degree slacker 66 degree head tube angle combines with a 20-25mm longer top tube and shorter chainstay length to create an evermore rally-ready geometry than its predecessor.

FAQS

Can I mount a chainguide to my bike?

No. We opted against including ISCG tabs, as one-by drivetrains have rendered them mostly unnecessary.

Is the 148x12 derailleur hanger the same as the 142x12 hanger?

No, it's not. We had to make a new derailleur hanger to go with the new dropout. They look similar, but the easiest way to tell them apart is the finish. Our 142x12mm hangers have a bead-blasted finish, while the 148x12mm hangers have a smooth, machined finish.

Should I grease the headset cups when I install them (Carbon Frame)?

Yes, we recommend this. Do not use the Carbon Assembly Compound on the headset, as it will make it more difficult to remove from the frame.

What is the torque spec for the seat collar?

We don't provide a torque spec for the seatpost, because it really depends on what seatpost you are using. Some seatposts are slippery, and require more torque to stay put, and others are very thin- and can be crushed by overzealous tightening. Some are both slippery and thin... Make sure you use the Carbon Assembly Compound included with your frame, and use some common sense.

You will not damage your frame by overtightening the seat collar, assuming you have a 31.6 seatpost in there.

What Kind of Front Derailleur do I Need?

The updated versions of the Bronson, 5010, and Tallboy use Shimano side-swing front derailleurs. The names and part numbers are:

Shimano XT M8020 Side Swing
Shimano XTR M9020D Side Swing

What kind of headset does this bike use?

Carbon: This bike useds Mixed Taper 1.5" Lower, 1 1/8" Upper headset cups

Alloy: This bike uses an integrated headset with drop-in bearings and integrated bearing races. The SHIS measurement is IS41 (upper) and IS52 (lower).

What kind of rear brake adaptor do I need?

This frame uses a standard IS rear brake mount. Just pick your rotor size and order the correct adaptor to go from IS to post mount (all modern brakes).

What size bottom bracket shell does this bike use?

We use a standard 73mm threaded BB. Nearly any crank on the market (besides BB30 cranks) will fit.

What size seatpost do I need?

This bike uses a 31.6mm seatpost. Always ensure it is inserted into the frame a minimum of 4" (100mm).
