2024 Santa Cruz Heckler SL

Can I put a 27.5" front wheel on this bike?

No, the bike is made specifically for MX wheels. A 27.5" front wheel would negatively affect the geometry.

Why MX (mixed) wheels?

MX wheels give you the stability and traction of a 29" front wheel and the agility of a 27.5" rear wheel. The smaller rear wheel has a lower axle height so you can more easily unweight the front wheel. That means confident and agile handling on steep descents. The drive unit also propells the rear wheel over rough terrain with no hang ups or lost momentum.

Do all sizes use MX wheels?

Yes, all sizes and builds.

I'm used to a 27.5" bike. What will feel different on MX?

An MX bike handles differently than a 27.5" bike. It mainly feels more stable and confident in the front end. Turning is slower, but it feels more secure in corners, and you get more traction. There's a taller front axle height and improved rollover from the 29" back wheel. Lessening your chances of stuffing the front wheel or being sent over the handlebars. Use these features to ride on more challenging terrain with a more dynamic body position.

I'm used to a 29" bike. What will feel different on MX?

A 29" bike has a ton of front wheel grip from the front wheel. Also from the axle height of the rear wheel, which keeps the front end of the bike weighted. These features give you a more natural riding position on lower-angle terrain, but you have to make adjustments for rearward bias. An MX bike has more rearward bias for a natural feel on steep descents. But you have to make adjustments for balance on flatter terrain. A lower handlebar, a more forward-biased suspension, and a Hi BB setting will make an MX feel like a 29er.

What's the recommended fork offset?

The bike is optimized for a 44mm fork offset.

What is the crank arm Q-Factor?

There are different chainstay lengths for each size. Can I use a different swingarm to customize my bike length?

The change in chainstay length happens in the front triangles. The pivot locations vary fore and aft to achieve the different lengths with a single size swingarm. No, you can't get the chainstay length of small on large, medium on extra-large, etc.
