Another bike maintenance question...wheels..

[Bigtallfatbloke]

...are the front and rear wheels supposed to spin att he same speed?....If I give th erear wheel a good spin it goes round forever...takes ages to stop turning. When I give the front wheel the same spin it goes around nicely but stops a LOT earlier than the rear wheel. Currently there is no chain set in place and I have the bike on a hanger. Is that normal or should they both turn as well as the rear wheel?

 

[Peter]

Perfectly normal. The rear wheel is heavier (with the cassette) and like you say, will spin forever.

Unless there is play or rough running in the front wheel I wouldn't worry. All it takes is a bit more grease in the bearings to make it spin slower unloaded.

good .Ta.

You're getting just a little bit too involved with your bike : )

If it's loads sooner, then I'd check out the bearings/tightness. As things go, if spinning the wheel, the rear should stop slightly sooner because of the slight resistance on the freewheel....spinning the wheels doesn't move the sprockets....

 

[hubgearfreak]

with the front wheel spinning, put a big screw driver onto the axle, and the handle end into your ear. do you hear grinding and grumbling, or does it sound like ball bearings rolling around in grease?

 

[Bigtallfatbloke]

I will try that...


This is a quote ref some Khamsin wheels I read at random

The hubs, also in anodized aluminium, ride on sealed high-quality bearings.

Does the bearings being in a sealed unit mean that if the bearings fail I need to buy a new wheel?

 

[mickle]

No, just new sealed bearings.

...are the front and rear wheels supposed to spin at the same speed??

While you're riding it - yes, definitely!
