Shimano makes great quality products even at this price point. This part was installed into an older bike with a failing bottom bracket. It made a huge difference and this new bottom bracket will likely outlast the bike at this point. Great product at a great price.

Muy fácil de instalar y su calidad muy superior, al ser balero sellado si se siente la diferencia en comparación de los cartuchos de balín suelto, el pedaleo es más suave y sin crujidos.

You can continue to relube or replace parts of your multi-piece bottom bracket, or chuck it all and replace it with a sealed cartridge. But which one? There are dozens of sizes out there....For older standard road bike (Trek, Giant, etc.) square taper spindles, you'll probably find something like this: BC 1.37 x 24 x 68 x 117.5. What does that mean? It seems that BSA/BC/ even ISO are identical layout in practical terms. 1.37 is the approximate diameter of the frame bore in inches. 24 is the threading (24 tpi). 68 mm is the bottom bracket width (left to right). Mountain bikes might be 73 mm. You'll find standard right hand threads on the left side, and LEFT HAND (reverse) threads on the drive side. The square taper ends are reportedly JIS profile, which fits most Asian crank arms. Install the drive side first (fully seated), then fit the left retainer. You'll need a Park BBT-22 or equivalent tool to install this assembly.Spindle length is the tricky part. My old one had threaded extensions with nuts and then plastic dust caps to finish the look. Cartridges are internally threaded, and you'll need to also buy hex head crank arm M8 bolts that include a rubber dust seal. Minus the threaded ends, my road bike spindle was 117 mm long (square end to square end). This cartridge claims to be 117.5 mm. The unpredictable part is that some old spindles don't have exactly the same amount of that 117.5 protruding on each side. Once installed, I had a very slight differential from the original, which increased the chain-line (chain rings pushed out a millimeter or so) which required adjusting the travel limit (H & L) screws on the front derailleur slightly to compensate along with a small shift cable adjustment. A quarter turn of each limit screw and I was good to go!

Sprockets Limited sent the item via Royal Mail 48hr delivery - fair enough......except it took 6 days to arrive. Not the seller fault and to be fair their comms is excellent. They respond within a couple of hours to any questions/queries.Anyway, the bottom bracket is here and looks fab - will fit it when I have a a spare hour or so. WIll probably use Sprockets Limited again.

はまらないので確認してみると、ネジ山が潰れていたり変に盛り上がっていた。シマノというブランドを信頼して買ったのにとても残念だった。
