Dude i forgot to mention, the store link with Axon u posted is kind expensive 300€ You can find it here for 190€ www.rczbikeshop.com (now it's out of stock and not listed) Usually they bring new stuff every month u should check it regullary. U don't need new wheel cause this is standard 9mm axle. But in your case i would choose something else for your lady.
I bought my Epicon six months ago from this seller (link posted above) no TAX charge, item was declared as gift. I choose mine based on reviews and did't regret it. Also u can go with Recon Gold, but they have it only in Black, still in great price. White is tappered 1.5 to 1 1/8, so no suited for her bike i guess. If u can find it better price go for Recon Gold, IMO. Always based on reviews. BTW if u can wait, try to check regullary RCZbikeshop, they listed RS Reba RL for 250€ But goes quickly out of stock.
Thats my suggestions. Good luck!
EDIT: Before you make up your mind, try and search reviews on net. Helps a lot. It's not ultimate guide but helps, many diffrent opinions and critics. Especially the one i mentioned in previus post, comparing 1000$ forks with 300$ and calling them s h i t........go figure.
I suggest you buy her a white rock shox reba and remove the damned decals. Tell her whatever you want until she tells you she loves it after the first ride. Alternatively, a Suntour epicon is pretty solid, has lockout, adjustable rebound, a 15QR bolt through, and a solo air spring.
Better yet, get some FOX decals from eBay, some gold spray paint from your local art shop and BAM, a pair of F120 RLC FIT Kashima's (for the first two rides).
