ProsGood value, does the job well.
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 due to technicality

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
It looks good

ProsGood value
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.
Good BB

ConsNon that I can see!
ProsVery good quality for the price, trusted brand, quality of manufacture
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.

Hi, both BBS18 and BBS15 have JIS taper?
By
14 Sep 2020
Hello, Yes both the Sunrace BBS15 and the Sunrace BBS18 use JIS taper.
What is the loose plastic washer for?
By
22 May 2020
Dear SJS,
I just purchased a BBS18 103 from you and there is a loose plastic washer included in the bag, I looked at the Sunrace website and drawings, but it is not clear what this washer is for.
I'm guessing it is intended to go over the spindle on the non-drive side, perhaps as a bit of dirt ingress protection?
thanks
Hi, I think the washer may be an error. I have checked some of our other stock and there is no washer. There is not normally a washer with bottom brackets so I think you should keep it as a spare. Thanks

Is this lighter than the BBS 15?
By
06 Oct 2019
Compared with the BBS 15 does this use aluminium cups & sleeve (compared with steel) and is it "78g" lighter?

http://www.sunrace.com/files/catalog/files/450/Specifications%20-%20Bottom%20Brackets.pdf
BBS15 has steel cups and weighs - 342grams including bolts.
BBS18 has aluminium cups and weighs- 282grams including bolts.

What is a BBS18?
By
20 Jun 2019
What is a BBS18 and what is the difference between your BBS15 and BBS18 Sunrace bottom brackets?
Hi,

the BBS15 is longer than the BBS18 and has a JIS taper.
What single chain set can I use form this BB with a 107 spindle
By
28 Feb 2018
I bought the Sturmey Archer FCS603 Single Chainset - Silver - 170mm - 33T for an 8 speed without realising it would not go with this BB. The previous BB had a 107 spindle, so I replaced that like for like. I have installed the BB and have decided that I do not like the chain set anyway. cheers

Hi,

We would always recommend choosing your chainset first and then getting a bottom bracket to suit, trying to work backwards does not usually work as you still need to achieve your desired chainline.

Thanks.

What Taper Is This Bb Please? Jis Or Iso?
By
19 Mar 2016
I'm looking for a narrow (102/103mm) axle length for an English threaded BB shell, And a JIS square taper.
Thank you.
Hi,

This bottom bracket uses a JIS taper. All of our square taper bottom brackets will be JIS unless they clearly state otherwise.

Thanks.
