SHIMANOUnisex Adult BB52 Bottom Brackets - Silver, Size 68

I have replaced the bottom bracket on my mountain bike tourer about 4 times in 10 years and each one has lasted thousands of miles in different conditions before starting to get crunchy.The price is reasonable, the parts are easy to find and replacement is easy with the park tool wrench. I’m a happy customer.

Straight forward quality no frills by Shimano

Bottom bracket arrived well packaged and full of grease, better than previous btm bracket I ordered.

Perfect fit for my Trek 6300 mtb, high quality genuine Shimano bb, comes with spacers if needed, also comes pre greased, very pleased

Easy to fit and great quality with good price. This has replaced the old version BB51.

For Shimano hollowtech cranks and equivalent Sram cranks.Fits frames with 68mm and 73mm width at the bottom bracket.The non drive side threads off and on as normal. The drive side has the opposite threading directions, it untightens clockwise and tightens anti clockwise.Clean and regrease the threads in the frame when the old bearing has been removed.Typically road bikes don't use the provided spacers but moutain bikes do.Check the service manual online to find out what spacers your bike needs and on which sides.Snug the bearings down tight into the frame.Grease the crank spindle before fitting.

Deore MTB bottom bracket - does the job fine, I usually replace every 12 months as it gets heavy use so no point getting the more expensive XT and upwards as they still wear out just as quickly

I see bottmo brackets as consumable items so going for value seems sensible to me. This should last a good season or two in the mud and dust. Usual shimano quality.

Feels as good as it looks, looks exactly like the one it replaced. Witch makes me feel really good about the job.

Eingebaut und passt.

Buena calidad y fácil de instalar

Dommage que la dénomination ne soit pas conventionnelle .... très compliqué de la trouver en faisant la recherche.

やっぱちゃんと出来てます。安心して使用できます。
