"I just wanted to follow up and let you know the Luftkappe and Fractive tune on the fork are incredible.  I have 3 rides on it now and have the settings almost all dialed.  Things I’m noticing so far:

1. The fork smooths out the small chatter making it much easier on my hands and wrists
2. Large hits are very controlled and it has a much more bottomless feel
3. The control it gives me going through chunky corners is scary good.  I’ve always liked the feel of the rear suspension on the bike, but it can’t keep up to the fork now in these situations.

I’m a very happy customer!  Thanks for the awesome service."

The No-BS Limitations

• Self-install on these is not simple. Please read the installation manual before ordering a kit for self-install and ensure you are capable and comfortable carrying this out.
• We do not sell tools for self-install of these parts at this time - Fox does however.
• This kit cannot address air spring concerns. Our Luftkappe upgrades however can help with that.
• Our valving recommendations are based on our testing, and are aimed at centering you in the adjustment range. The range of adjustment is quite wide, and you will still need to spend some time finding the setup you like best.
• This will not turn your 100mm travel XC race bike into a 200mm DH bike. Sorry.

WARNING: VORSPRUNG products should be installed and serviced by a trained bicycle service technician, in accordance with both VORSPRUNG and original manufacturers' specifications. If you have any doubt whether or not you can properly service your suspension product, or you have not performed this kind of work before, then DO NOT attempt it. Improperly serviced products can fail, causing the rider to lose control resulting in SERIOUS INJURY OR DEATH. That's not a joke. Don't mess around with it if you don't know what you're doing, because the best case scenario is usually that you damage something in the process.
