Reviews over the

Shimano XT MT800

Quality bottom bracket from Shimano. If all parameters are correct easy to assemble. Runs like a sewing machine. And hopefully for quite a while.

Pros & Cons

Very easy installation with the right tools. The bb is also quite light but feels very strong and stiff while pedaling.

Pros & Cons

Not much to say about a bottom bracket, except that replacing it has been very easy for me. Very easy, and the MT800 is a good upgrade!

Pros & Cons

The product is as described. Very good quality/price.

Pros & Cons

Excellent bottom bracket. Fitting is a breeze. Cycled about 100km with it, can't say much else about it.

Pros & Cons

See pluses. Glad you are with these people in Oosterbeek

Pros & Cons

It fully meets expectations.

Pros & Cons

This BB is smooth and quiet. It not not very heavy and is sealed. The BB itself is small and discreet, and improves ride feel

Pros & Cons

Since there was probably sand in my bb51 bsa bearing (precursor bb52), I installed this slightly more expensive and hopefully better mt800. To disassemble the bb51/52 I bought the bbb spanner BTL-27L (44 mm) and to install the mt800 I bought the adapter tl-fc25 (44 to 41 mm). Previously the adapter was included in the package I was told, now it was not. Installation was pretty simple, adapter does go very tight in the key, but 't fits. Now I have a smooth-running bottom bracket again. Unfortunately, I can't say anything about the durability yet.

Pros & Cons

exactly what you expect

Pros & Cons

Does what it needs to do and is easy to install.

Pros & Cons

Nothing to complain about! Now for further testing in practice.

Pros & Cons

Beautiful black anodised bottom bracket with mounting direction laser-engraved. Lockant on the thread and well greased inside. Fitting is perfect. Just be careful to refit the shim rings properly so that your front derailleur/chain don't hit. Mounting is with a 14-tooth tool, but an insert for a 16-tooth is included! Top.
