Creaking
By Evan Stuber

Bought one of these a couple of months back and already getting a load of creaking. Is there a way to stop this?
SJS Customer Service:
Hi there,
It is worth removing, cleaning, regreasing and refitting. If you are using a carbon frame, it is worth checking, systematically, every single part on the bike. Things like mech hanger bolts being slightly loose can make a noise than sounds like the bottom bracket is toast!

Can this be used with a 2013 Canondale CAADX?
By Anonymous

I'm trying to convert my CAADX from FSA Cranks to Shimano Cranks(ultegra,105). Will this product do what I need?
SJS Customer Service:
Hi there,
This may fit, from experience in many Cannondales the cable routing can cause issues. We would recommend heading to your local Cannondale dealer.

can i use pus this bb on plastic cups
By celilcetiner

i have pf 30 plastic cups on bb came with bike. bb diameter is 46 but with cups on it inner diameter is 42. do i have to remove the plastic cups ? or can i put the kcnc bb on plastic cups ?
SJS Customer Service:
Hi there,
We would need to see the bike in question to confirm this, if they are suitable reducer cups then it will fit fine. Be aware, there is a highly likelihood of a noisy bottom bracket with multiple adapters.

What Is The Diameter Of The Centre
By Magnus
11 Apr 2017
Can you tell me what the diameter of the centre is?
I want to fit this to a Felt F1 FRD. The frame doesn't have a clip inside it but a slightly smaller diameter so a praxis bb doesn't fit.

Installation
By Tim

Should this be installed with grease, or not necessary because of the o-rings?
How (and how well) are the bearings protected from dirt and water entry?

None
SJS Customer Service:
Hi,
You can indeed change the bearings in this bottom bracket adaptor. The old ones can be pressed out and the new ones just need to be pressed in.
