SRQ/JIS Aluminum Sealed Cartridge Bottom Bracket ENG with Bolts

I ordered this BB instead of others in the same price range (such as Shimano UN55) because it came with crank arm bolts, or so the description says. This BB is to replace a mid-80's style Sugino bottom bracket (the original on a 1985 Trek 300) that used nuts to attach the crank arms to the spindle. I didn't want to spend an extra $7-$10 on crank arm bolts as this BB was going on my bike trainer BB. I received the package today and it did NOT come with crank arm bolts. I went to my local bike shop and they gave me (no charge) crank arm bolts from their spare parts bin. If you don't have crank arm bolts, buyer beware! The description says they come with bolts but mine did not. Had I known that I would have opted for the UN55 as Shimano is a much better known brand vs. Neco. The quality of the Neco seems fine. I installed it today and I'll do my first trainer ride today.

My original part was steel housing and cups. This replacement is aluminum. It's much lighter. I believe the durability is not affected by using aluminum. My old part came out (I needed to use a bracelet removal tool) easily. My new part installed easily. It took me about 20 min. So far, so good! 🙂

It was nice looking but didn’t feel smooth, I ended up going with the other brand.

Came only with one crank bolt

Great product and I love it

Expect to get a 1-2years of service out of the bb.

Works as it should
