Are Offset Mountain Bike Rims Good Idea



Why are MTB rims offset?

To start with, offset rims do one thing: they equalize tension between the spokes on each side of the wheel. This makes it less likely that the lower tension side spokes will go slack, fatigue, and eventually break. That’s all.

How much wheel offset difference is OK?

It’s best to allow an 1/8-inch of play for potentially wider tires. See all 11 photos Offset not only affects how far the wheel/tire sticks out of the fender well but also its proximity to suspension components like knuckles, and control arms.

Does offset affect handling?

Too much positive offset (the wheel sits too far in towards the car) can cause damage to inner suspension and brake components from the inside lip. This can lead to poor handling making the car unstable at speed. Sometimes the rubbing will happen on the inner sidewall of the tire causing a rupture of the tire.

How far will offset stick out?

Well-Known Member. Yup.. – 12 offset. Sticks out sbout an inch.

Are asymmetrical rims stronger?

Rim beads are symmetrical, even on asymmetrical rims. Now, if you are talking about the wheel coming out of true, then an asymmetrical rim/wheel will be stronger. The reason the rim is asymmetrical is so the spokes from opposing sides are closer in length, creating a more even triangulation.

Can you decrease wheel offset?

There are many wheel spacers with varying thicknesses which allow you to change the offset of your wheels quickly and easily. Wheel spacers essentially increase the distance from the centre of the wheel to the hub, thus reducing positive offset.

Does negative offset cause rubbing?

If you get the offset or backspacing wrong when you are procuring and installing new wheels for a customer, you run the very real risk of having the wheel sit too far inside the wheel well, causing the inner edge of the wheel and tire to rub against the suspension.

Is lower offset better?

Looks: A smaller offset moves the wheels outward, so they have a tendency to fill out the wheel well better. Cars set up for show, more than performance will often choose a lower offset wheel, however, if the offset is too small the sidewall will rub the inside of the fender.

Does offset affect fitment?

(+) offset pushes the wheel farther into the caliper/brake. Extreme positive offset can result in poor overall fitment due to the wheel tucking, or even worse, suspension rubbing!

Is negative offset good?

If your offset is too positive, you risk the inside of the tire hitting your suspension. To fix this, bring the offset down, so it’s closer to zero. This moves the tire out. If your offset is too negative, then the outside of the tire will rub on the car’s body and fenders.
