Today I broke one of my own rules: "never change your equipment right before a race." I've been bothered by some tendonitis in my elbows for a while, so I changed the length and angle of my stem in a last-ditch attempt to reduce the strain on my joints.
Under normal conditions, however, I would never make changes to any of my gear so close to the season. As I suspected, when I rode today, the handling and fit of my bike just doesn't feel good. I know it will take several weeks of riding until my new position feels "right", and that's exactly what you don't want to start the season.
Depending on your location, as of today you are probably 2-6 weeks away from your first race - and at this point in the pre-season you should have your equipment choices firmly decided on. The last thing you want is to have to change a component out without plenty of time to test and adjust it! Here are some parts and accessories you can check NOW to avoid having to make last-minute changes on later:
'Cross is coming! Make those final adjustments to your gear and I'll see you at the races.
