I was helping out a friend adjust the travel on his 2011 Reba S29 w/Brain in his Specialized.

Opened it up and removed the spacer to 80-100mm.

After gettin it all back together, the Brain was super harsh right around the first 20mm of travel, no matter how firm or soft we adjusted it.

Do you have to adjust something else within the Brain cartridge when changing the travel?

Can't find any info on this anywhere on line.

We ended up putting the travel spacer back on and it worked just fine.

Any help is appreciated.
