SHIMANOSM-BBR60 (BSA) Ultegra Bottom Bracket

Really easy to fit, just make sure you have the right tools at the start and lubrication for reassemblyThere are no special knacks for putting back together. The tightening direction is printed on the parts.Just take your time, work in a light and spacious area, I was in my kitchenI turned my bike upside down but a bike stand would have worked as wellGood part. The previous one lasted 4000 miles. I am expecting the same or better from this

Great bottom bracket but be aware that thus item does not include the adapter. Some do.

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 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!

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.

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!

This is a bottom bracket. it does what it says. good quality, seems like the original part, not counterfeit. bought 2-3 of them already, all great
