Have you found what you are looking for:

Do the pulleys require any maintenance?

In general very little maintenance is required for our pulleys due to both the seals and thick grease which is pre-applied.
If you would like to keep them fresh after heavy use, or long mileage and you are confident in peeling back the bearing seals with a scalpel or similar sharp blade, the bearings can be lubricated with a slightly thicker grease, such as lithium grease. Generally this is a good consistency for the bearings.

Will the anodising wear off after use?

Because the tips of the teeth on the pulleys are coming into contact most frequently with the chain, slight visibility of the raw aluminium colour can be expected after consistent use. This will not gradually expand in size however and will only be apparent on the very end of the pulleys at the contact points. Once the pulleys are kept clean, the overall colour of the body will not change over time.

Are the pulley wheels noisier than stock plastic pulleys?

While we dont have a lab based conclusion for this, measuring comparative sound levels, the level of noise when compared to stock plastic pulley wheels should be unnoticeable on a well maintained, lubricated drivetrain.

Will these work with Shimano 11 Speed Groupsets

These are intended for use with the listed 12 speed groupsets only. For further clarification about compatibility with your specific groupset, please use our Pulley Selector Tool.

Hi Ward,

As we already noted to you by email to your previous query, you did not receive them because after checking your shipping address inputted at the checkout, you did not put in your full address, your house number was not listed there. As mentioned at that time that unfortunately, as the address submitted from your side was incomplete, our options to assist further are limited and recommended you follow up with the shipping provider to request further details on the parcel.
