Don't worry, I got you covered for a winter dropper post! There is only one choice. Fox Transfer SL, all mechanical and I've never had an issue with mine in the deep dark Alaskan winters. For some reason, us flat pedal fat bikers are looked down upon. All the "serious" riders are using SPD's or Eggbeaters. I like my flats, just less things to worry about.
The rally car went into the shop today cause the brakes have been feeling fairly shit. They couldn't find anything mechanically wrong, broken, or really worn.. but did get a couple bubbles out and refreshed all the fluid. Pedal feels quite a bit better now and they only charged me $115 for it all. Okay, it's not really a rally car but it is a Subaru Impreza that I've lifted, added lights, and some little details that really make it rally inspired. Really I just made it fit for driving in Alaskan winters. Anyways..
I rode my bike to and from the shop and decided that winter time drivers really are not looking for a bike even tho I had lights and reflectors. So many encounters that could have been bad if I hadn't been purposely looking out for myself. Negativity aside, it was about -8*f in the morning and about -2*f on my afternoon leg and I mixed in a couple little trails and detours along the way to boost my attitude. Good ride all around. Picture is at about 8:40am and facing south, the sunrise wasn't till 2 hours later.
Earlier this week I finally made it to one of the group rides and three of us wandered around the valley. Our ride leader had a vague idea of the route he wanted us to do and we sorta just made it up as we went. None of us really knew if all of the trails we wanted to ride were actually put in or not yet. Definitely ended up on a couple of sections that we had never been on before. First visit to the creepy penguin house this season! The penguin appears to have vacated his tree since I last saw him.. perhaps he'll reappear later in the winter. Trails are surprisingly good with the lacking of snow so far to fill in all the tussocks.
