Weight Weenies

These are reasonably priced and based on the feedback I've across they seem to be solid bottom brackets. Anyone know about the following?

-Is the BB body metal or plastic?

-Are the bearing seals low friction for road or high sealing for cyclocross/mtb/wet riding?

-When the bearings wear out, can they be replaced or does the whole BB need to be replaced?

-Are the bearings a standard size?

Thanks in advance.

If I may ask, where are you planning to buy the bb from?

There is a seller on ebay named mr_ride that seems to carry most of their products if not all.

http://stores.ebay.com/mrridebicycle/

I can answer a few of the questions:

-Looking closely at a couple of their BB's the seals say 6806-2RS, so they are standard size bearings
-and double sided seal so good for wet weather riding.
-The BB bodies have machine marks so must be alloy rather than plastic

Still not sure if the bearings can be easily pulled out to service.

I haven’t had the best experience with the same vendor. He was slow to respond to messages and after a month of waiting patiently for tracking information, I lodged a complaint and received my money back. Don’t know why he never posted the bb. Wishbone themselves also don’t answer emails......

For what it’s worth I’ve purchased a bunch of KMC chains from mr_ride over the years and never had an issue.

I’ve been thinking about getting the Wishbone Threadfit Shimano bottom bracket for the C60 for a while now but can find very little if anything about them.

Wishbone started their business with carbon wheels (I have a pair, basically Gigantex stock wheels) and then switched to making bottom brackets for all kind of combinations, but I can't speak for this as I didnt have chance to try.

You may as well wait to see what Ceramic Speed has come up with for the Colnago C64. It should work on the same premise as the Wishbone solution in that it’s an option which replaces the Threadfit cups which come standard with the frame.

I also posted this info in the thread: Colnago C60 - Campagnolo bottom bracket. I apologize if you are seeing it twice.

I contacted Ceramicspeed to find out when information will be available on the Threadfit 82.5 bottom bracket solutions for Colnago models with the TF82.5 standard. Below is the reply:

Very much interested in the Ceramic Speed BB. I saw they are making one, cheers.

@cal - I have mad respect for your knowledge on all things Colnago, especially BB solutions. I would have just sent you a PM, however it does not seem that I am allowed to yet (anyway to get a hold of a mod so I can pM?)

Anyway, as you know I’m building up a gorgeous PLWH c60 at my local bike shop (which is a great shop and has a great reputation - Fairwheel bikes aka madcow on the forums). The build overall turned out fantastic with DuraAce, however I was expecting a HSC ceramic BB and when I went to go pick up the bike, it had a dura ace bb (that’s a fraction of the cost). Is DA 9100 a suitable alternative to HSC? Should I have considered ceramic speed BB? Will I notice a difference?
Thanks

It's fine... you likely won't notice a difference while riding. I wouldn't worry about it. As long as it isn't creaking or develops a creak you're good. Nothing worse than a creaky bottom bracket. But that's largely a function of how well it was installed in the first place and whether a retaining compound and primer was used. Colnago actually recommends a dry install. I used a little Morgan Blue Aquaproof Paste just as a preventative antiseize agent. But do not use grease. Grease is your enemy when installing a pressfit BB... as it just facilitates movement and while it may "mask" the noise from the movement for a while, it's still allowing it, and that will eventually creak again, but worse, cause excessive wear on your BB shell. In Colnago's case, with the Threadfit BB, if something like that ever did cause excessive wear the solution is very simple, you just replace the Threadfit cups. Unlike a lot of other bare carbon shell frames where, if wear occurs, you're kind of stuck with it.

The Ceramicspeed customer service representative has apologized for the delay in updating the website to reflect the new T45 bottom bracket solution for Colnago Threadfit 82.5 bottom bracket equipped bikes. Here is the latest reply:

Hi Gary

I am sorry for the late reply and the bad news about you can´t see it yet.
Our website is working against adding this to the website. But I hope it will be up next week. This is being worked hard on by our webmaster.

I ordered a Wishbone Thread Fit 82.5 bb for my C60 from mr_ride last May. The bb showed up quickly after a smooth tranaction on eBay. The bb spins ok right out of box, not super smooth but acceptable. My LBS wrench who did the installation complained that there isn't much space for his thin Park hollow tech 2 tool to grab. As result he needed be really careful not to strip the cups. Anyway everything was working fine after the installation. Few months later a different LBS wrench removed the bb to fix the Di2 junction box rattling. Shortly after the bb started to creak. It took a few tries but finally the creak was solved by tightening the bb a little more. The LBS wrench said he was afraid strpping the cups and that's why he did not tighten it enough during the isntallation. I grabbed the same bb from LBS while visting Taipei last December since I always like having essential spare in my part bin. I noticed this one spins very smooth out of box. I guess either the first one is bad or the company switched to different bearing.

The new Ceramicspeed bb looks exactly same as one from Wishbone and that means tightening the cups can be little tricky. Personally I think $400+ for a bb is little crazy since a $40 DA bb86 will work fine for few years. But someone here will remind me about my $6k frame............
