SHIMANOSM-BBR60 (BSA) Ultegra Bottom Bracket

I got this when I realised that my ten year old Shimano Tiagra 4500 bottom bracket needed replacing. It is very easy to fit - just remove the crank, unscrew the old bottom bearing, and replace with this. There are lots of very good videos for this, I found the Park Tools ones best (you want the one for the BB with threaded shell, and the one for two piece crank removal).The only thing to be aware of is that this is a smaller diameter than the other (?older) Hollowtech II BBs - so you cant directly use your existing tool. However, this does come with the plastic insert that makes your larger diameter tool work - you just slot the plastic insert into your existing tool. Depending on the actual tool you have, it may or may not work. It didnt fit into the Ice Toolz or BT WIN tools I had, as the plastic insert was slightly too large in diameter. Other people have also said that it doesnt fit, but the simple fix is to file down the outside of the plastic insert until it does fit. Gentle use of a plastic mallet will help too.

I found there seems to be a large array of bottom brackets to choose from, but many say they are for mountain bikes. I was after one for a road bike compatible with CLARIS R2000 Series main gear, as I noticed my current one had a square taper crank fitting, but my lovely new one I had imported from France was a spline fitting ie a series of teeth. Other people in my club said I needed a Shimano Hollotech II bottom bracket and then looking at the Shimano site for the main gear you can see the recommended bottom brackets shown under PRODUCT SPECIFICATIONS which is this one for a threaded frame :)

10 minute job provided you have correct tool. This part will last a approximately year. Dont know the difference between tiagrathru to durace apart from cost.Would I recommend? Yes.

Shimano BB for road bike does exactly what it's designed to do hold your 105 cranks on with no fuss fit and forget for the next 5000 miles 👍🏻

I remember the old days trying to set up the awful square taper bottom brackets, murder. Even the internal bearing sealed bottom brackets seemed to give me loads of problems and never lasted long but the shimano hollowtech bottom brackets have been rock solid.I generally seem to get around a year out of a bottom bracket, but I ride all year round and have been caught in some horrific weather. Cheap, good quality and takes 10 minutes to replace. The direction of the threads are even marked so you can't make a mistake, love them!

Easy to fit to bike and the chainset fitted in perfectly

This is a good quality item, but is no longer provided with the adapter in the box.

This is a straight replacement for a SM-BB7900 I have on my Specialized Allez Comp. If you have the BB removal tool for the BB7900, this BBR60 comes with the adapter to allow installation of the new BB.So far I am happy as the replacement took only 15 mins and seems fine so far.Will go for a longer ride tomorrow so will see how things fair. But so far, all great!

I was setting up a Zwift setup for winter training and decided to pull an old bike down out of the garage rafters to give it a new life and the thorough going over.She was put to pasture once I became addicted to Di2, carbon EVERYTHING, disc brakes, and tubeless tires. On another tangent, I've forgotten how wonderful metal is as a frame material. The feeling and feedback is something that's gotten lost in the match towards "higher tech". This bike will now be the rotation again, once the weather warms and I purchase a set of tubeless wheels ...some tech advancements are just too good to ever go back.Ok, back to my BB review...The part arrived rather quickly and I hadn't finished putting on the new cable housing and cleaning/lubing the drivetrain so this was out on the back burner, since I wanted to get the Zwift sled up and running ASAP.In time I got the Zwift thing down and got the bike dialed in on the (Zwift) hub, so though now I had time to pop in the new bottom bracket.I knew the original Ultegra BB was ok and still turned smooth after 15 years and thousands and thousands of miles, but I bought this new BB on a whim when gathering up fresh parts for this project. I saw how Shimano claimed lighter weight and a 50% reduction in friction, but we know how "NEW AND IMPROVED!", sells so didn't buy too much into the hipe. I opened the box and thought I purchased the wrong part because the BB threaded shell looked WAY too small compared to the old one still in the bike 🤔I fished around the box looking for the advertised adapter that's supposed to come with the BB so you can use your older took to install the new gen BB, but it was nowhere to be found, which is why I dinged the review on ease of install ... be warned, you'll likely not have the right tool to put it in if you're used to servicing your old BB.Once the correct tool arrived I swapped in this new one, put the bike back on the trainer and put on my kit for a ride.🤯 I couldn't believe how much LESS energy it took to power the bike! Shimanos claims of friction reduction are not hyperbole. I could see it on in the Zwift data too, I put out fewer watts over the same courses I'd ridden several times. Data doesn't lie, this thing was a huge improvement in efficiency and you can see it in the data. To add to that, it cleans up the looks of the whole BB area and makes it look far more modern.In closing, even if you don't NEED a new BB you need this for the friction reduction and sleek looks and ... IT'S CHEAP!!!Get it, you won't regret it other than needing to buy the tool to install it if yours doesn't come with promised adapter! 👍🏽

Die Lagerschalen sind im äußeren Durchmesser kleiner geworden, was der langlebigen Funktion keinen Abbruch tut. Sieht aber gerade bei Stahl und Titan Rahmen besser aus.Die Qualität der Lager ist um jeden Zweifel erhaben!

Movimento centrale Shimano che e ' sempre una garanzia di qualità , in più il prezzo e' competitivo , montato su un gruppo Ultegra , tutto perfetto. Per la durata bisogna vedere in futuro per il momento tutto ok .
