I recently purchased a Linkin Ultimate 135 (at a substantial discount) and was surprised how many extra bits came with it:

Two extra headset spacers
Different angle headset cups
Two tubeless valves and 125 ml bottles of Synchros sealant
Front fender
Crank arm boots
Small magnet (and two spares) to measure rear shock sag and travel
…

Initially rode it in the default setup and stock configuration (other than removing Fox front fork volume spacers and swapping the wheels with a hand-built carbon set). The “save the day” tube/pump kit is cool though adds 430g and separate mini tool (magnetically attached in the same underside compartment) weighs 76.5g.

Liked the feel of it overall though the carbon bars (with integrated stem) seemed a bit low. I added the extra pair of headset spacers (raised it a total of 1cm above the steer tube) and will have a go with it again today.
