wheel bearings and gas mileage

I noticed my gas mileage was down this spring, and while changing my front tire I discovered that the wheel bearings were turning less than smoothly. Two new bearings later and the fuel economy is back to normal. Just a suggestion for anyone who is noticing poorer fuel economy, to have a look (and more importantly, a feel) at your wheel bearings. Cheers.

Good point. I have to pull both wheels to get new meat mounted next weekend. I be sure to check them well.

I can well believe a bad bearing would drop your milage. The bags, tail trunk and tall windshield "Robbed" me of close to 5-7 mpg. But, What'ya gonna do?

Or was that look THEN leap?

I reckon the bearings would have to be very tight to turn or even seized to have an affect on gas mileage.

Wheel bearing drag is in fact directly related to fuel efficiency and power transfer. Up to about 15% increased fuel consumption can be experienced without it being obvious that the bearings have developed extra drag.

Do you happen to know what the proper bearings are for the V? I was thinking of getting new bearings but wiuld have just ordered oem's.

Also what is the average life span before replacing? I have 25k on my V. When I lift the wheels on race stands I have no play in the wheels.

A parts supplier like cheapcycleparts.com will be able to size them for you, but frankly they are so cheap that I get mine at my local shop - it's hard to get screwed on a $5 part.

Wheel bearings seem to be one of those things that get sourced from different suppliers, so there isn't really an "oem" part. I've tried "All Balls" and a different brand, they didn't seem to perform or last any different from one another.

The bearings would have to be really bad to notice play in the wheel, and would likely be making a racket by then. The best way to check is with your fingers, which means taking the wheel off. If they feel notchy or gritty when the inside race turns then they're due to be replaced. If you are careful removing the dust seals they can be re-used (they are actually more expensive than the bearings).

I check the bearings any time I have the front wheel off (usually for a tire change) and this is the third set of front wheel bearings I've put in at 85K kms. I've changed the back ones once. I've noticed the same phenomenon each time: increase in fuel consumption prior to the change.

Just one last thing: this would be a tough DIY job without a bearing puller. Harbour Freight probably sells a cheap one.

Front wheel bearings: 2 x 6004-2RS (C3) with rubber seal on both sides.
Rear wheel bearings: 2 x 6204-2RS (C3) with rubber seal on both sides, 1 x 6205-2RS (C3) with rubber seal on both sides.

I spent $$$ on a set of World Wide ceramic bearings for my land speed bike and I can not believe the difference in just pushing the bike around.

I gotta agree. A set of old, worn-out bearings would make a difference in fuel mileage.

Good post Mt. Versuvius!

This is what comes up for "All Balls" on cheap cycle parts for the V. It says that it is a wheel bearing kit. For $18 is that all of the bearings needed for the front and rear wheels? Seems to cheap to me to include everything... But I dont see anything else that could be added to it.

That's about what I paid for the front wheel kit (All Balls) last year. The kit is the bearings plus the dust seals. I doubt if it would be for both wheels but who knows? Parts are a lot cheaper for you guys in the States.

Edit: With cheapcycleparts I find it's better to call and speak with someone, since I can't always find what I'm looking for on the website. They have been incredibly helpful and nice with me on the phone.

Another thing to bear in mind when talking fuel efficiency - your chain. IF it's properly lubed you'll find it will spin through several rotations each time you spin it with your foot (the V on a rear stand, of course), and when the chain is dirty it WON'T, so the lubed chain will translate to better mileage.

Thanks for the answers Mt. V, and Invader. I called them up to ask questions about the needed parts, and was helped out. Unfortunately the email that was sent to me does not list the part #'s I am getting....

The parts that show up on the web sight is only 1 wheel. He looked up the proper parts in his books, and got me everything needed. Front cost $18, and rear $13. I also got brake pads for it as well while I was at it.

can tyre weight effect fuel economy , I put a set of BRIDGESTONE BT 54's on as that was all I could get and now my fuel economy has dropped quite a bit

I would say the type of tire and how it's made is more crucial. The weight should be very similar. But if its a softer rubber that grips more, you could lose some mpg, though grip the road better. If you're having any significant loss in economy, it may be some other means mechanically, or maybe you're just riding harder.

It didn't suffer that much. You just got a taller and heavier rear tyre... Which sizes did you get? 150/70 rear?
