シマノのBBは、その精度の高さと耐久性で定評があります。実際にMTBで使用してみると、ペダリング時のパワーロスが少なく、スムーズな回転を実感できました。特に、ハードなトレイル走行時でも、ガタつきや異音が発生せず、安定した性能を発揮してくれました。取り付けも比較的簡単で、専用工具があればDIYでも交換可能です。ただし、ネジ山のグリスアップなど、正しい手順で行う必要があります。シマノのBBには、様々なグレードがありますが、上位グレードのBBほど、回転性能や耐久性が向上します。予算に合わせて、最適なグレードを選ぶと良いでしょう。全体的に、シマノのMTB用BBは、高品質で信頼性の高い製品だと感じました。MTBでの走行性能を向上させたい方や、BBの耐久性に不満を感じている方におすすめです。

Does what it should.Much smoother pedaling than my used one.I ride every day up steep slopes which wears these brackets out with time but I should see about a year or two of use from this with this in mind.30 dollar replacement is probably the best value.

Sehr preiswertes Patronenlager mit begrenzter Haltbarkeit. Bei meiner belastungsintensiven Nutzung hält das Lager rund ein Jahr (1200 km).

Bought this to replace the bottom bracket in my Voodoo Limba. I thought I had purchased the right size, but it is a little narrow - the non-drive side recesses about half a centimetre. Doesn't impact the performance - the wobble from my cranks has gone, bike runs great again.When researching how to install the BB, some people said the cap supplied with the BB doesn't always fit - mine didn't. I kept the cap from my old BB and it fit in perfectly.

I installed mine in the winter of 2022, adding additional grease around the bearings and seals and it saw light offroad use throughout the spring and early summer of 2023. It wound up put away early last season, but I've had it out a couple of times this spring and it quickly developed a wobble. I removed it to check it and both bearings were rough and rusty. It was stored in a heated, dry, basement all winter.

Remplacement boîtier de pédalier d'un VTT de 1999 Lapierre faisant 112mm de long. Modèle livré fait 115mm au lieu de 113 prévu alors dû modifier le réglage du dérailleur avant. Sinon semble ok, pas de jeu ni de dur. A voir dans le temps
