ShimanoUltegra SM-BBR60 Bottom Bracket Cups(Return to Product Page)

Lucked into an opportunity to get an Italian-branded frameset for an amazing deal, and needed an Italian threaded BB for it. Have used the the English threaded version of this BB for a few of my previous bikes as well as for friends' bikes that I've worked on and they've always been a great value. The Italian threaded one I picked up recently wasn't any different - aside from the thread direction :-D - and BTD had it on sale which really made it a no-brainer.

I've tried some of the knock-off BB's that are out there, and they will work alright initially, but they don't stand up to the same abuse as this Shimano one and with BTD you're not spending much more than the knock-offs anyway, and over time you're really saving money because you don't need to buy a new one every few months. You can also spend a lot more to save a watt or two or to add some bling, but if you just care about your BB working well and want the best bang for your buck, I'd look no further.

Replaced the BB on my 4 year-old / 19,000 mile Specialized Roubaix. I opted for the Park 59.3 BB tool rather than using an adapter. I replaced my crank at the same time because a full crank on sale wasn't much more expensive than the regular price of the big chain ring that I needed to replace.

I hadn't done a repair like this on this "generation" of Shimano drivetrain technology. It was surprisingly easy to do. If you have moderate wrenching skills and access to YouTube, this is definitely something you can do at home.

I had never replaced a bottom bracket and was a little intimidated by the prospect. But this was one of those repairs that was far easier and faster than I ever expected. If you're already doing some of your own wrenching, replacing one of these is about as easy as it gets.

I use this bottom bracket on my bikes with shimano hollowtech cranks. Never had an issue with it. It's light and still pretty cheap. One of those products you can install and forget about.

A threaded bottom bracket is a thing of beauty and this one did not disappoint. Lightweight, clean, and precise -- everything you'd expect from Shimano. This one went smoothly into my Surly Straggler, allowing me to re-purpose an Ultegra groupset for an all-steel, all-terrain ride. My only complaint was that it required yet another BB tool to install it.

I replaced my old Ultegra bottom bracket with this new 6800 version. There was substantial engineering effort put into this to decrease the drag from the seals. It's noticeably smoother and easier to pedal.

Do note that Shimano now has three different sizes of bottom brackets so you'll need the right tool for each. DA 9000 is the smallest in diameter, then Ultegra then 105 and none of them are the same size as the old outer diameter. Shimano includes a plastic adaptor with each bottom bracket to fit the old size Shimano tools (from Park or others). However, when you try and torque it down to the required 35nm or so, it's very easy to strip the plastic adaptor. Plan on getting the right tool ASAP. For this bottom bracket the right tool from Park Tool is the BBT-59.

Anyhow, this is a great deal in a BB in terms of cost and performance.

You can have it in any color you want, as long as it's black. The threads are not very robust, so make sure your BB is perfectly clean so you don't have to use any effort to thread it in. The seals look pretty effective, but probably not on par with a sealed cartridge. It seems pretty straightforward to set the preload, but the smallest change can make a noticeable difference in resistance when spinning the crankset by hand (and with no chain).

That's the end of the bad news. Otherwise, it is really lightweight and it feels like there is zero friction when you have it dialed in. Oh, and it's super cheap compared to any of the sexier options out there.

I am a fan of this style BB and wish all of my bikes had a threaded shell. Simple, straightforward installation, and quite economical. This is a noticeable upgrade to the previous 6700 BB that had a lot of bearing tension on the spindle, this unit spins much easier. I would give 4 stars but that durability was an issue previously and unknown with this new unit. However, with the reduced bearing tension I do expect that it will last much longer.

This shimano bottom bracket simply works, and looks great. Even comes pre-greased at the bearing interface, ready for you to install your crankset.

I had similar issues with the tool adapter, specifically using it with the park tool BB total. it was a tight fit tool-to-tool, but it works. In contrast to other review, I was able to get it plenty tight by being careful.

Numerous comments talk about an included tool to help with the bottom bracket install. The part I received, SM-BBR60B, says "SMBBR60 BC137 W/O TLFC", and does not include any installation tool. I have a Park Tool BBT-59.2, which is the correct tool for installation, so it's not a show stopper for me ... but might be for someone else if you're expecting an installation tool to be included.

BBT-59 is the installation tool to use. Shimano's included tool strips out before the BB is torqued properly.

replaced the worn out bottom bracket on my Felt. Price was great and it was shipped in a timely manner.

Upgraded my Specialized Roubaix SL4 Sport to all 105. This BB paired easily with the 105 crankset. Easy to install. Ove 1000 miles and no issues

Shipping was fast, product fit perfect, 100% satisfies, as always! Will definitely keep ordering all my parts from BTD! Your the best!

It's a lightweight product and does the job well for some years. Easy to replace.

I bought this to rebuild a road frame for use on my Wahoo Kickr. It's been low maintenance and reliable with an older Dura-Ace crank set.

This bottom brackets works great. Excellent performance for the price. Be forewarned, that noise that you think is the bottom bracket might actually be chainring bolts, or your seat post, or....

Not a Chris King, but for the price, does what is should.

Once I was able to determine which bottom bracket to order this was a perfect fit. The instructions and the included adapter tool made installation very straightforward.

Bought this to replace my 5 year old bottom bracket on my Bianchi. This bracket is very reasonably priced, it's light and easy to install.
