On a warpath to convert all my machines to 49mm. The Linea Micra is the latest to be transformed!

Convert the group head from 58mm to 49mm with a simple bolt on replacement.

Hidden benefit after converting is that the portafilter will seal with just your pinky strength. No longer will you need to ram the portafilter on with all your might to guarantee a leak free seal!

Installation guide can be found here

Compatible with:

• Linea Micra
• Linea Mini
• GS3
• Linea Classic Multi-Group
• Likely compatible with many other LM machines but I am unable to test it

Kit Includes:

• 49mm Bayonet Unit
• Shower Screen
• Two group head seals (one spare)

Note:

• *At this time, only my portafilter has been verified to be compatible - which works with all of my 49mm Billet Baskets. The OEM Cremina portafilter is compatible but it is uncertain if all of them are as it was produced for decades - there may be variations or design changes over that time period.
• Aftermarket CNC machined Cremina/La Pavoni portafilters should be avoided due to the narrow/small mounting lugs.
• Not compatible with La Pavoni portafilters
• Baskets are not included
