Rotor UBB 4630 universal bottom bracket pf30 bbright bb386 threaded (5)

Love the threaded BB30 solution from Rotor Bike Components? That same threaded pressfit design is now making its way to more bottom bracket “standards” thanks to their new UBB4630. For whatever reason some bottom brackets tend to creak – some claim it’s the fault of frame manufactures, while others claim it’s a fault of the BB design itself. To help with the issue, Rotor is adding a more secure aluminum threaded pressfit bottom bracket to complement their current UBB line.

Whether you have a frame with a PF30, BBRight, or BB386 shell, the UBB4630 is here to help…

At the core, the UBB is a threaded aluminum shell with two matching threaded cups. The threaded mechanism takes some of the locking function off the press fit shell which is said to allow for a more precise installation and a more secure fit resulting in better spin and less noise. According to David Martinez, Rotor’s head of engineering, “The motive for the UBB4630 was to address challenges related to bottom bracket installation and durability with respect to specific frames.” He goes on to say that the UBB4630 will reinforce their current UBB line.

Sold in PF30, BB386, and BBRight fitments, the UBB has a claimed weight of 109g and will be available with either steel or ceramic bearings ( 89.99€ and 199.99€ ).

Hey! Nice Enduro Bearings Torqtite, I mean Rotor Torqtite.

It isn’t Torqtite, not even close. Torqtite is a mindless goofball solution that requires you to loctite the entire threaded BB into the BB shell. They are soooo sonfidnt in their threads that they recommend loctiting the BB into th BB shell. LMFAO!

These Rotor BB’s are spcifically designed to work with grease only during the install. ZERO loctite!! And FYI, Rotor was making threaded BB solutions like this for 24mm spindles on BB30 frames back in 2010, years before Enduro essentially copied their idea with Torqtite. This Rotor product is simply Rotor applying their 24mm spindle threaded tech to 30mm spindles.

I’m just over here waiting for a nice fix for my BB30a frame…

That’s funny. I actually did put one on my BB30a Supersix, the Enduro version. It’s been available so I didn’t have to wait for the Rotor version. LOL

Adding threads to fix problems created by removing threads. Brilliant.

Threads in standard bb’s do not thread the BB halves together, nor do they prevent creaking in any meaningful way and never have. I have had loads of traditional threaded bb’s that creaked beyond belief. My curent BBright Cervelo is easily the most quiet BB of any I have ever run. It has literally never made a single peep of noise from day one. These Rotor threads are specifically on the bb itself to hold it together, and prevent movement in the bb shell. Traditional threads do not do that and never have in any meaningful way unless they were loctited down.

how about a solution to Specs less than optimal OSBB that is 61 mm? Their PF30 sleeves fallout when you clean them to reduce the creaking noise. LBS said it’s not defective.

Specialized has two solutions: epoxy their plastic cups, a removable solution; epoxy in their newer aluminum cups, a non-removable solution. I’d recommend their aluminum cups and be done with it. From then, it’s essentially a bb30 frame.

Yeah, and if the problm is with poorly fit bearings rather than cups you are thn stuck with a permanent problem, not a solution. 🙂

A PF cup or a sleeve in a PF shell was never meant to have something spin in it (trust me, I torched a frame after a BB bearing ceased). The idea of threading a BB into a cup sounds like a short term solution that will create a long term mess… that won’t be covered under a frame warranty.

It may look like that but in fact ROTOR has been using the same solution for 24mm axles and BB30 frames since 2010 (I think)…and even then it wasn’t something really new.
Those BB’s work great and are currently used in pro teams (not sponsored by ROTOR) to prevent frame damage from BB’s.
This new BB extends ROTOR’s UBB range to 30mm axles, and differs from similar solutions especially in the way it prevents bearing overload with respect to the frame’s bottom bracket shell.

I’ve been looking at my options for a new carbon full suspension frame and all of them except the Santa Cruz Tallboy have Pressfit 92 BBs (Spez has PF30 but I just don’t want one of those either!).

Look at Ibis. All three of their full suspension bikes use threaded bottom brackets.

The idea and product has already been out there for a a while people. This is just an exact copy different aesthetics.

Rotor has been doing this since just before 2010. Only difference was that BB only applied to 24mm diameter spindles. All they have done is now extend the same tech to 30mm. They were one of the vey first companies to offer threaded bb solutions for Bb30 and PF30 bb’s.

Again (and again) to all you thread lovers: There are valid reasons to remove threads from the BB shells of carbon frames. So yes, it indeed is smart to move the threads to the (aluminium) bottom bracket cups.

What is wonder is why i am recommended to pull out my current pf bb, clean it and press it in again with some grease. I think my bb was mounted with some adhesive like Loctite.

I also know when frames with direct press bearings creak, the only thing to solve it, is take them out, clean the housing and press them in with housing greased.
Now it seems i am recommended to do same with a pf (with sleeve) bb.
This is the opposite from fixing them with Loctite.

I can’t find the Rotor threaded pf anywhere!?
Anyone knowing when this is available?
