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.

Tech Support

Can I mount a chainguide to my bike?

Yes, this bike is equipped with ISCG-05 tabs for easy chainguide mounting.  Most chainguides on the market that are made for this standard should work.

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?

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 kind of headset does this bike use?

We use a headset generally referred to as "mixed tapered". This is a 44mm internal upper cup, with an external 49mm lower cup. The SHIS name is ZS44/28.6 EC49/40.
