Purchased this item years ago for my old PX-10-LE. Wow, what a great addition to its last rebuild. The bearings are smooth as butter, and there is no play in the crank spindle. It really made the bike feel better, there is no movement as one watches the chainrings spin around! I couldn't eliminate that slight wobble with the old cup and cone bearings.

(First time customer) After receiving this B.B. and a pair of hubs, I came away with a grateful feeling, and an immediate desire to purchase more, which I will. It is definitely refreshing to run across a business that sells quality products at a good price. Thanks for that. These parts are light, run smooth, and have class written all over them, so to speak.

Then there's the niche factor: For people who are looking to restore their beloved vintage bikes, these guys offer valuable products that are not exactly flooding the market. And once again, offer them at a great price.
I am very satisfied.

1. It was the lightest of the three 68x110mm BC1.37 BB I bought at 421g (positive). (Shimano BB-UN300, heaviest 467g and IRD QB-95 at 436g).
2. The non-drive side cap barely fit my Park Tool BBT-32. I had to really wriggle the BB piece until the openings seemed to open up a little. The metal on this non-drive side cap seemed somewhat flimsy, also. (negative)
3. I do not like any pre-applied material on the threads. (negative)
4. It was not the cheapest, not most expensive of the three BB. (neutral).
So, I installed the IRD QB-95 on my bike as it seemed like a more solid metallic BB and turned most easily of the 3 I purchased.

English Threaded Bottom Bracket

One of the English threaded bb cartridges seems to have an unusual amount of drag after installation. It may loosen up after some use, but in the work stand, you can turn it with one finger and give it a spin ... but it only spins about 3/4 of turn, even with a hard spin.

The stars grade on this review is for another English one I have installed, as well as the French one a bike shop put in for me years ago - both work GREAT!
