So I was out for a ride yesterday and experienced something a bit unnerving that I am trying to get to the bottom of. I was coming down a hill, coasting with my hands on the handlebar drops, in something of a tuck. Around what was probably 30mph my front wheel began to shimmy left and right. It was not up and down at all, the handlebars were pulling left, then right, then left, etc. It wasn't violent enough to lose control or grip, thankfully, and sitting upright and applying the brakes lightly was enough to end it. It never happened again, but here's some info...
- New bike, Scott CR1 Team. Was checked by an LBS after who found nothing noticeably loose.
- I had my front wheel off before the ride and again between taking it to the above LBS. Why? I didnt want to fuss with the rack and just threw it into the trunk of the Highlander. At any rate it is possible the front wheel was too tight or too loose during the ride if this would be a possible cause. Tips for making sure it is right?
- There was a decent headwind. I was coming down a hill (Page Mill between Foothill and EL Camino, for those that know... not huge 150ft), but there's little between it and the SF Bay. Reading online says this can be a cause.
- I'm a novice rider so it is entirely possible my form was off, putting either too much or too little weight on the drops, if that could be a cause.
Thoughts, tips, and things to make sure to check into highly appreciated!
