Frequently Asked Questions

2022 Santa Cruz Bronson 4

  • Why mixed wheels?

    It's the stability and traction of a 29" front wheel and the agility of a 27.5" rear wheel. The smaller rear wheel and its lower axle height make it easier to unweight the front wheel. So you have confident yet agile handling on steep descents.

  • Does every size have MX wheels?

    XS has 27.5" front and rear wheels. All others have MX.

  • Can I fit a 27.5" front wheel on this bike?

    Only on XS. It's made for that size.

  • There are different chainstay lengths for each size bike. Can I buy a different swingarm to customize the length?

    The chainstay length change happens in the front triangles. The pivot locations are varied fore and aft to achieve different lengths, while also using a single size swingarm. So no, you can't customize it.

  • I've been riding a 29" bike. What will feel different on MX?

    29" has a ton of front wheel grip. The bias is more rearward on MX. That makes it feel very natural on steep descents. It does require some body position and setup consideration to feel balanced on flatter terrain. MX also has a slightly lower handlebar and a more forward-biased suspension setup. The Hi BB setting gives it a more front biased feel.

  • I've been riding a 27.5" bike. What will feel different on MX?

    MX handles differently than 27.5". It has a more stable and confident front end, and slower turning. It also has a taller front axle height and improved roll-over of the large wheel. So there's no chance of stuffing the front wheel or going over the bars.

  • What's the recommended fork offset?

    Most sizes have 42-44mm offset forks. XS has a 37mm offset 27.5" fork. That's what's recommended for optimal handling.

  • What's the biggest rear rotor that fits on this bike?

    180mm minimum, 223mm maximum.

  • Why are there two measurements for BB Drop?

    BB drop is the measurement between the center of the bottom bracket and the front and rear axles. The Bronson comes with two different wheel sizes, so the drop is greater up front.
