TrVuativ bb adapter, anyone used one?

Has anyone here retro fitted the TruVativ BB adapter? It allows you to l fit your old single piece bb with a newer sealed unit & allowing for three piece cranks. I have it on order but thought I'd see if anyone else has used one?

Cheers,

They work great. I use one in a Schwinn Super Sport, it's a popular conversion. It will not accept an old-style loose-ball (or whatever you call it) bottom bracket, only a sealed one.

I've had a bear of a time setting them up and have also had them work well. It really depends on the quality of the frame you try to convert.

Some light reading (read my post on page 3)- https://www.bikeforums.net/showthread...apter-Problem?

Did you read that thread? They can be a BIG pain in the ass if you're not careful.



What's the frame?

Some will accept a standard (cup and ball) bottom bracket. See the very informative article here where the complete install of such a conversion is documented: https://hughsbicycle.blogspot.com/201...erican-to.html

I just did this on a 71 Super Sport. It went smooth, but you need to take your time and not force it. Here is the end result.

I used one on my '73 Super Sport. It's a terrific piece of hardware.

Scooper, nice looking bike! What are you using for a front derailleur, and what is the tooth count on the crankset? Thanks for the reply, I'm still getting mine dialed in, and the crank/front derailleur are not perfect yet.

Thanks for the pics! Looks great... I just dropped my frame off at the powder coating place this morning. Going with a basic gloss black.

The front derailleur is Campagnolo Comp Triple, and the crank is Campagnolo Comp Triple 30/42/53t. I'm using Centaur Ergo shifters, and the drivetrain works flawlessly.

I was told it was a 68 Norco. Other than that, I haven't a clue.

Thank you, your bike looks really nice! I have a 22" frame that I'm working on now, it fits me perfectly, and also a 24 " frame that I'm going to do as a winter proect. I can ride it, but it's just a touch big.

Did you test fit the adapter before you dropped it off?
