Well...As of last week I finally hung up the commuter shoes. I was able to go pretty deep into December this year, it was warmer than normal. I was able to get a good handle on gear when it got colder, but I just don't have gloves that I like. They're either too bulky or not warm enough, I need so spend some time on that and get something I like. All total, including mileage on both bikes, and some mountain bike rides, I estimate that I got close to 2000 miles in this year, I am pleased with that.
I usually spend the off season cleaning up the bikes and doing any requisite maintenance that should be done, yanking bottom brackets and cleaning and lubing, etc. In most cases I will end up upgrading something, as I get antsy if I'm not changing things around. This year, my main geared commuter (KONA Sutra) will not see any upgrades as I got that thing pretty much where I want it. I am focusing a little bit on my fixed gear (Surly Crosscheck) and my geared Strong hardtail.
Just a few minor changes to the Surly. I am going with a smaller, faster rolling tire. I like the big 32c, but I will go down to a 28c and sacrifice a little girth for a better rolling tire. Gonna try the Panaracer Pasela TG, the gum sidewall should go pretty well with the beef gravy colored frame. In addition, I am gonna get a honey colored Brooks B17 for this bike, I have one on the KONA and really notice a difference when I am not on a Brooks.
As for the geared Strong, I am going over to a full SRAM drivetrain and see how it goes. Looking at an X9 rear derailleur and x9 trigger with a new SRAM cassette and chain.
This year I am also upgrading and changing around my wife's Raleigh hybrid. She's been using that to pull the kids over to my daughters preschool. Now, this is currently a stock hybrid, low end suspension fork, suspension seatpost and the like. I watched her pull the trailer and she was bouncing so much it was working against her and it just didn't look efficient at all. So....She's getting a rigid fork, and really a whole new front end (headset, bar, stem, shifters, brake levers, etc). I had a couple things in inventory, and got some good deals here and there (eBay). Oh, and I am replacing that blasted suspension seatpost...jeez...
I will more than likely throw new tires on the KONA, waiting for the new Schwalbe Marathon Duremes to hit the stores...That pretty much wraps up my off season maintenance/upgrade plan, just waiting for some parts to arrive so I can get started....
