What are, if any, the signature postural differences between riding a 26″ bike and a 29″ bike?

Can I replace 26 inch wheels with 29 inch wheels on my Giant Sedona?

You cannot just mount a larger tyre, even if you had the clearance. The larger tyres need also need larger rims, that usually means you need complete new wheels. It is unlikely that a frame for a ...

Would a hard tail 29er be a good starter bike for road and light trails?

Short answer yes, a hard tail 29 would be a good fit for what you have described. And it sounds like you already have a fun FS bike and a road bike so it only makes sense. The equation N + 1 comes to ...

Why mountain bikes had originally 26 inch wheels?

Wheel & tire sizes are a source of unending confusion. The more you learn, the more confusing they get. 29" mountain-bike wheels have the same bead-seat diameter as modern road bikes: 622 mm (...

Bontrager thorn-resistant vs self-sealing tubes?

Wheels for fat guy - 27.5" vs 29"

In theory, a smaller wheel is stronger than a bigger wheel if hub and rim section are the same. This is largely due to the length of the spoke and it's contributions to the stiffness/flex vs spoke ...

What are, if any, the signature postural differences between riding a 26″ bike and a 29″ bike?

If the three contact points of Hands, Feet, and Backside are in the same relative places, then the rider's static posture will be identical regardless of the bike's shape or wheel size. But nothing is ...

Can I replace 26 inch wheels with 29 inch wheels on my Giant Sedona?

If they are disk wheels, it may be remotely possible. If not, no, the rim brakes in the wrong location. 29" is much larger than 26". Being the front fork, its possible, but unlikely a 29er ...

Do 27.5" wheels fit a 29" mtb?

They fit, in the sense that you can install them in the frame (if the axles are correct, hub width is correct, etc). The problems are: The bike stands a few centimeters closer to ground. Which means ...

What features does a mountain bike need to be converted to an ebike?

What features does a mountain bike need to be converted to an ebike?

The cassette and hub will depend entirely on the conversion kit - is it a front wheel, rear wheel or center drive? If rear wheel, you probably will replace the whole wheel with a choice of swaping the ...

Do 27.5" wheels fit a 29" mtb?

Yes and no. Installing them with normal sized (2-2.3") tires will result in that much less ground and pedal clearance as well as tweak the geometry of the bike. So that's not likely to work out well. ...
