BSA is another way of stating English threading; it comes from British Standard Cycle. English threading on road bikes mean a 68mm wide, 34mm inside diameter shell with reverse threading on the drive side. It’s the most common threaded standard employed today. This kit works with 24mm diameter thru-axle cranks, found on Shimano, FSA, Rotor, among others.


Choose between two bearings for the cups. Standard Bearings have low drag thanks to hardened-steel races and our Ceramic balls. Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag.

In The Box

  • 2 threaded cups with bearings.
  • 2 dust covers with built-in spacers.
  • Spacer tube.
  • All Round Grease.
  • Sticker sheet.

English threading is easy to work with and the drive side cup, thanks to being reverse-threaded, stays in place without extra effort. 24mm spindles easily fit through the shell, allow for large bearings to be employed in the outside cups.

Put more of your energy into forward motion by reducing frictional drag wherever you can. CS Standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That’s in the range of a 75% drag reduction compared to standard bottom brackets. CS balls are 100% smoother and 15% harder than ceramic competition. The bearings last at least 3x longer than other bearings.

Race Day Grease, All Round, and Long Life are greases CS designed to help the bearings roll smoothly. The first is the least drag, the last is the most durable. All Round comes in road bearings, Long Life in MTB. You can change the grease to tune performance.

Really cool! But it’s already torn a bit!
Size: One Size, Color: Duke Blue Devils
We liked the label DUKE on the basketball it was perfect for our Duke boy puppy but unfortunately it already tore a bit. I would have given it 5 stars if it wasn’t for that!

Not for your Chewers
Size: One Size, Color: Purdue Boilermakers
My 7 month old English springer spaniel loved this toy from the moment I took it out of the amazon box until about 15 minutes later when she had torn a whole in the ball. Thankfully we were able to remove the basketball section and she was able to chew on and play with the rope for a little longer before we tossed it.

Perfect Calming Bed for Puppies
Color: Dark Gray, Size: Small - 23”L x 23”W x 8”Th, Color: Dark Gray, Size: Small - 23”L x 23”W x 8”Th
I bought this calming dog bed for my 10-week-old puppy and he absolutely LOVES it. The moment I put it in his pen he curled right up and fell asleep. The soft, fluffy material is incredibly cozy and supportive, and the raised edges make him feel safe and secure. As a new puppy owner, I wanted something that would help him relax and settle down, and this bed works amazingly well. He sleeps so peacefully in it and clearly feels comfortable. The quality is great, the cushion is thick, and it holds its shape nicely. If you have a puppy or a dog that likes to curl up, I highly recommend this bed. It truly is a calming bed! Bonus: it also looks really nice in the crate.

Amazingly soft! My dog loves it!
Color: Dark Gray, Size: Medium - 30”L x 30”W x 8”Th
If you follow the instructions inside for fluffing the bed, it's AMAZING! I myself sat in it and it was so soft and very comfortable. (I need one for my bed!😆) If you also follow the sizing chart, it's pretty accurate. My dog loves it!
