I bought a Patriot66 a few years back as I was scared of breaking the ‘lighter’ Five. I should have listened to the lad in the shop “The Five will be fine, the Patriot is overkill unless you are spending alot of time in the Alps”. I’ve since bought a 4″ travel XC bike and the Patriot gets used for trail centres and the odd trip to the Alps (like once since I bought it). The rest of the time I ride the HT or 4″. The Alpine isn’t that much different to the Patriot66Xcel, really nice bike, can be ridden long miles, but heavy and Sofa like.
The Five will be fine, unless you live in Morzine or Les Gets. I can’t imagine you’d ever break it (I was 15.5st when I bought the Patriot and it was still overkill). Buy the Alpine if it’s NOT your only FS bike, if you want to do lots of miles and a few trips to the Alps then get the FIVE.
If you really are v.worried about breaking the frame then I’d suggest buying one of the big US names and getting a lifetime warranty. Orange only warrant frames (or bikes) for 1yr.
