I've just recently bought a new bike with drop bars for my daily commute. It's great fun and actual feels quite comfortable after following a few fitment videos and guides online.
The bike is a single speed Kona Paddy Wagon.
I have no pain or strain while riding, however at night the tendons on the of inside my elbow tighten up and get quite sore when used. It is really hard to pinpoint the pain, but it's not muscle, it's tendon. However the pain happens whenever I bend/flex my arm with the palm down or thumb up. When the palm is up, it doesn't hurt.
I'm not even 100% sure it's because of the bike, but the position my hand is in during the pain is basically the the hood position, so it makes sense.
Had anyone experienced this? It's what I imagine tendonitis might feel like.
During my attempt at setting things up, I managed to take a couple photos, I don't know if they help or not.
