ConsTake your luck on quality
ProsNever have to hook out bearing fragments again
A nice solution to the problem of sourcing good quality conventional cups and bearings for my 1938 Holdsworth, although quality control is suspect. The first had a faulty bearing (replaced promptly by SJS) but the thread on the cup of the second unit is so badly cut and undersized it simply fell out. While the last 70 years have seen some inevitable wear on the frame the original (but damaged) cups screw in just fine. A nice idea, poorly executed.
Great Upgrade

Part was not in stock but email updated worked great. The bottom bracket came with metallic cup. Only problem with part is that the standard ice or park bottom bracket tool does not fit due to the length of the drive spindle.
Superb Delivery,

ConsLoss of originality
ProsWill never need to butcher the cups to get them out again
I'm restoring a 1950s Rudge and decided to compromise on originality in order to get the maintenancefree advantages of a sealed unit. The cost compares favourably with what some "old cycle" specialists charge for wellmade conventional cups and bearings, and since the Rudge still has a chain case, you need to look hard to spot the difference.

I was really happy to find this product as I couldn't get original cup & spindle BB to fit. Thanks for stocking a very niche, but indispensable product!

In the picture, the bottom bracket seems to have metallic cups, that´s why I ordered it. I was very disappointed when I received a bracket with black plastic cups.
I had one of those already :(

Hi there,

Would you be able to tell me whether this ships with metal or plastic cups?
