The Titanium Bottom Bracket Thread

The Titanium Bottom Bracket Thread
I have a few vintage titanium bottom brackets and while most of them are bordering on OT, I have seen a lot of interest in vintage Mountain Bikes here. My next project is a TBD vintage MTB rebuild. I think the 90's were a super fun era of customization with cool american made anodized parts and lots of machining. Hell you can still customize your mountain bike heavily today, but must of it is carbon now and I was a wide eyed young teen in the 1990s drooling in shop windows at anodized parts (kooka, cook pros, ringle, salsa, syncros, paul, chris king, and so much more)...
I digress. Unfortunately I sold most of my syncros BBs, but I still have 1 and a half.
Please post photos of your titanium bottom brackets and any other information you have... some brands I know of.
1. Syncros

2. American Classic

3. Cook Brother's racing

please add yours

Of course there is Phil Wood, Campagnolo Super Record, and maybe something specific to the Viscount... But I am more interested in the 1990s era stuff. I have a few unidentified ones, which seems off as most examples have the manufacturer engraved on them... I would think a high end item like a ti BB would always have done so, but apparently not... I'll photograph the unidentified ones and post photos at some point.

I just had to remove an Edco TI spindle Bottom Bracket as the bearings went south. I think I will be able to source replacements, (I hope anyway). My guess as to why is failed is due to the inherent flex of the ti spindle.
So, I would look for one or repair one that had an oversized diameter ti spindle if you had a choice.

That GT BB looks very similar to a Phil wood (but they all kind of do in a way). I'd be curious to see the whole spindle.
THe syncros BBs came in several configurations which I do not know the names of, but some models had a double wide bearing with two sets of ball bearings per side... there was also a version with "inset" bearings and the face of the cup was depressed... I am not sure why they would want to place the bearings closer to the center, but maybe it was to reduce the stress on the center of the spindle and allowed them to make the spindle lighter? Not sure, but it seems like it would be more flexible.

A UN-5x is around 300g while a UN-7x is around 250g a UN91 is claimed to be about 220...
I put a phil wood Ti-magnum BB on my road bike with my 185mm TA Carmina cranks to save weight. With the alloy cups it's under 150g. So pretty significan't weight savings if you are a weenie. And I was trying to get my steel road bike (carbon fork) down to 17lbs in an XL size. I eventually succeeded, but with a dura-ace 7800 180mm crank-set. I still use the TA's and my classic lugged, road bike with fenders though. That is a for life crank and BB set.

I wanted to pull the GT BB apart, but I'm afraid I'd never get it back together.

The sealed bearing cartridges marked #61903RS are machine pressed onto the spindle, which is generally a good thing, but there is a complication. After one of the bearing cartridges is pressed on, an anodized aluminum tube with the "GT" logo is placed over the spindle before the second cartridge is pressed in place. This tube is precise fit and conforms perfectly to the outer diameter of the cartridges.
Most other B/B with machined pressed bearings have a gap between the water sleeve and the bearing that enables you to slide a piece of plate steel to support the bearing as you rap with a hammer to free a failed bearing for replacement. These pieces fit so tightly, and have no gap, replacing a bearing should it fail is likely to leave some real physical damage on the remaining parts.

I think one of my unidentified BBs is a later syncros.. I didn't realize it.. as it has the cups which utilized the shimano tool.. I like the older ones better... Also looks like '97 was the last year for syncros.

No pics right now, but I have a Race Face Ti BB. It's square taper, & the cups are anodized blue, probably aluminum or some alloy. I've had it around 5-ish years, but it's probably a lot older than that. It came with the old Race Face Forged cranks, when I got it used, & the seller said they were the same vintage.

Wow, never heard of that crank and BB Jeff. that's awesome. I also curious to see the raceface BB, are the cranks blue as well spacemanz? What bike are you using them on?

Just the BB cups are blue, the cranks are a very plain (for the day) silver anodized aluminum billet. I've mostly used it on Cannondales, I think it's on the Silk Road 500 now.
EDIT: I know my posts are weird here, not my fault, a weird connection-type thing. The first post went missing for a bit.

I don't have any pics of mine, but I have 3 Ti BB's. All fairly old one's that haven't shown me any problems (yet). Although, Teledynes were prone to breaking..

I think the open ball and cone bearing design is much more forgiving of a flexing spindle. That written, I wonder how much additional friction that flex brings upon the bearing system?

On a somewhat related note, I thought I heard that Ti axles with built in Ti cones would wear out quickly, because the bearing race was not as durable as a comparable steel race. I think this is why most companies used sealed bearings. Of course, I can't remember where I heard this, and I may be wrong.

Well, here's what we get for pics, LOL. I have the cranks on a XT/Ultegra BB on the F1000, because it fits that frame better on length. It's definitely a little heavier than the Race Face, but it's weight doesn't matter as much as on a road bike. I dunno if I ever posted the old F1000, I should sell it off & reclaim some space.

Yes, titanium alloys aren't anywhere near as hard as steel alloys can get. The Zeus 2000 bottom bracket I pictured above uses pressed-on hardened steel races on the axle and in the cups for the bearing to run on.
