Hub and bearing servicing

Postby Ed Stanley » August 16th, 2013, 6:55 am

Chris, Jon,

Sorry for the somewhat random questions (as always). I've just purchased a pair of Flo 30s from you which are clearing UK customs as we speak. We were really desperate to get these as Frankie's qualified for Vegas and Kona and we're going to take out the 60s and the 30s to give her a choice of wheel.

When I bought the 30s a few weeks ago I had the usual problem of several hundred people trying to buy them at once (no fault of yours other than producing such good products!) and only the ceramic bearing were left by the time I logged in so I got them. On the assumption that Frankie will probably be doing more racing on the 60s than the 30s and that there may be a tiny peformance advantage in the ceramics I'd quite like to swap the bearings over from the 30s to the 60s. It looks like this should be possible but I'm not clear on how best to extract the bearings from the hub/axle and didn't want to fiddle too much for fear of breaking them. Do you know if this would be possible and, assuming so, how best to go about it?

On a related note, one of our other wheels (I think we're up to four sets of Flos in the house now) has a strange 'tick' noise coming from the rear wheel. I've tried the wheel on two bikes, the spoke tension seems (not actually measured yet) to be consistent, the wheel is true and I've tried swapping out the cassette - all to no avail. My next trick was going to be swapping the freehub but I thought it could also be the bearings (steel on this one). If it is the bearings (again by no means certain or even likely) is it possible to buy some replacements from you?

Many thanks in advance for your help and all the best,

Ed

Ed,

Thanks for writing. To answer your first question, I would say that you will get little to no benefit from swapping the bearings. You will need some special tools and in all honesty I don't think it is worth your while. If you are still dead set on it, I can try and run you through the process over the phone or skype, but you risk damaging the bearings. Just my two cents.

For your second question. When are you hearing the "tick" noise? In other words, what causes the noise to occur? Sprinting, shifting, etc.

Thanks,
Chris Thornham

Hi Chris,

Thanks for the very quick response.

Thanks for letting me know. I may well just leave that then and be content in the knowledge that I have contributed to the Bike for a Kid program :-) I think having something on the website covering bearing servicing would probably be a good thing for you guys in the long run though. Even my Chris King hubs need a service/swap occasionally given the lovely long, wet winters we've been having in Europe recently.

On the second point, I will check with the boss/rider but my recollection from her original comments (this happened in June in the middle of a big block of racing so she just stole my Flo 90 after we couldn't fix it quickly) was that it happened mainly under power (especially peak accelerations/out of the saddle climbing) but did occasionally happen when freewheeling and could be felt/heard over the (awesome sounding) freewheel on fast descents. There's a lot of clearance on the frame at both chainstays and seatstays, changing the cassette didn't make a difference and the noise stops when the wheel is taken off and occurs on whatever bike the wheel is put on so I'm pretty sure it's something in the wheel. I've taken the freehub off and it looks fine. No particular wear etc. Any help gratefully received!

Thanks again and all the best,

Ed

Thanks for the thoughts on the bearing service info Ed. That is something we will likely work towards in the future.

Regarding the noise. It appears like it is happening during hard efforts. Are the spokes by chance dirty? We've had customers in the past with dirt between their spokes cause this same type of noise. Let's start with that.

Take care,

Thank Chris!

I had the same thought as I had the same issue with some Planet X wheels a few years ago. These are spotless though. The problem came up during ITU Long Distance Worlds so the bike had been fully cleaned beforehand and I've just checked the spokes again and they're pristine, even the contact areas where they cross.

Any other ideas?

I'm taking the wheel out to Vegas next week as backup in case it's too windy for Frankie to use the Flo 90 so I'll try and get a better handle on the symptoms when I'm out there.

All the best,

Ed

Ed,

I'd double check to make sure the end caps on the hubs are secure and that the cassette is properly installed (eg not missing a spacer). Also, you may want to check your valve stem. Sometimes those can be smaller than the valve hole and they make a tick noise when the wheel rotates. The valve stem/extender falls from one side to the other.

If you can shoot a video of the noise that would be helpful as well.

Thanks,

Hi Chris,

Thank you so much; you guys are great. I've taken off the end caps again, greased lightly and retightened. The cassette has all its spacers but doesn't have the silver one that comes with the hubs (so it could be that?) but there's no play at all in the sprockets (either from side to side or rotationally). I'll give it anothe go tomorrow and try to get you a video/audio file. I'll also swap the inner tube and check the extender. It feels snug but you're right it could be that.

I tried it on a short ride near Vegas today. The noise was most noticeable during low cadence/high power periods such as on seated, low cadence climbing. It was less pronounced on the flats but still clearly audible. I couldn't hear it over the wind noise on the descents and it's either much quieter or else not present during freewheeling. When climbing side by side Frankie's Flo wheels (actually my 90 that she's stolen!) were silent and my 60 was making a real racket.

On the plus side, I've brought my new 30 front out and it's wonderful. Well done to you both for getting it to market.

All the best,

Ed

Ed,

Are you in Vegas? If so, how long are you here and where are you staying?

Hi Chris,

Sorry I missed this! only just found the email. Yes we were staying in an appartment about 50m from the start! Had a great time.

I've taken a video and will upload it to youtube so you can see what I'm talking about.

Alternatively, we'll be on the big island in a few weeks if you are going to be there too?

All the best and thanks again (to you both) for all your help,

Ed

P.S. The 30s are great! nice work!
