After a show where I met some people of Token I received a box fool of goodies from them. In that box where not only the T33SL wheels which I will review later, but also one of their Tiramic bottom brackets.

What is Tiramic? I hear you ask. Tiramic is a surface treatment that Token uses to coat the races of the bearings they use. They coat the races of the bearings with titanium. According to their marketing blurb this treatment makes the races harder then normal steel. Normal steel races combined with ceramic balls will wear faster then titanium coated races combined with ceramic balls.

Now that we got that out of the way we can talk about the BB some more. it comes neatly packed with a few spacers and a shim for use with shimano or the Sram/Truvativ GXP system. Since I use a Sram crank I installed the shim in the left cup. since the shim is equipped with an o- ring it stays securely in place.

Installing the BB went easy. screwing something in place isn't that hard. Shimming something out is on the other hand. It took me a few installs and pulling things apart again to make it work properly. In the end I also took out the plastic bearing covers as I felt that they slowed things down as well.

In use things started to creak after a 500 km. The crank was removed and the bb was taken out. The shims needed some grease on them to kill all the sounds. The cranks spin smoothly and the bracket doesn't make its self know. If you ask me that is a good thing for a BB!

Enough! We want pictures!
Not much, it is a BB for x sake!

Hi,

Impressive stuff, Frankie. 8)

If you don't mind, the treatment of the bearing races is actually a titanium nitride coating similar to what you see on the gold coloured KMC SL chains.
Personally I use some of their tiramic ceramic hybrid bearings in a square tapered Ti BB (6903 size should someone ask) which I run on oil much like Campa's CULT bearings. They work great, no probs whatsoever.

Ciao, ;)

I have used a Token Tiramic BB on my training bikevfor 3 years now. It has been ridden in rain and on pretty rough roads with no issues to date, bike has had a major service once a year.

IMO a pretty good upgrade, comes in a range of colours, is pretty much fit and forget, spins smoothly and doesn't require much maintenance. I'm a 95kg rider so it has been used hard with no issues, so definitely something that I can recommend.:thumbup:

I've used the Omni Racer, rebadged, and have them on two of my bikes and they are very smooth bottom brackets. 2 season on the one on my tt bike that uses the Sram adapter for my Sram Quarq and the other on my single speed 29er second season too.

So, you all think their bearings are great? What life are you getting from them?

This does not say that all of their BB's are bad. just mine failed a bit.

A full review wouldn't be complete without knowing if a company really stands behind it's products. So it's really nice that you were willing to wreck those bearings in a weeks time :lol:

Hope you can get a replacement set and have better luck in the future. Keep us informed

Even though i effed up Token stands behind their product and send me a new drive side bb.

The nut head that I am I neglected to look up the installation manual on the web and installed it as I saw it fit. Turns out I put an o ring in a wrong position. leaving a cap for the crank to have some play. that is what destroyed the BB.

Here is a pic of what should have been done:

Small update on the BB: A few hundred KM later the BB is still working fine and spinning smoothly. It functions just like it should do and doesn't leave me in thoughts about it.
