Sunrace BBS18 68 mm Shell English Thread Sealed Cartridge Taper Bottom Bracket

I recommend this product

Replacement for Shimano BB-300 which only lasted 7000 miles. A good part, which has done 250 miles to date, will have to wait and see how long the SunRace lasts.

Noted this part has aluminium cups not steel as stated..

Arrived promptly and well packaged.

SJS reliably stock precisely this the bottm bracket in the right size that I repquired to replace the similar one originally fitted to my bicycle. The original one had performed well over 12,000 miles of energetic hybrid style cycling before its bearings went which seems to me a good recommendation. The result of fitting the new one is excellent.

Good snug fit in the frame, smooth running bearings and after a couple of fairly hard rides cranks have kept tight on the tapers.

Not used yet as the chainset is an old 23.3 thread and trying to locate removal tool looks good and comes with crank bolts

Replacing a Shimano BB-UN52 which has lasted 22 years on my MTB through all sorts of riding. I hope this lasts as long! It has alloy cups, one is fixed to the shell and the loose one has a thin plastic insert which is designed to take up the last bit of play between the shell and the cup. If this fails after a while, I have found that Loctite 641 bearing fit retaining compound stops it creaking. If not, then it's your knees! Trust SJSC to have the less common axle lengths. It comes with normal black axle bolts. The 107 length weighs 250g without the bolts.

Looks and feels well engineered. Certainly better than the unbranded one it’s replaced. Fitted very easily and looks like it should give long service.
