Here's my story. Rode Mtn bikes in 90's-00's. 5 years ago decided to pick up cycling again. wanted to ride on paved MUP's and roads. Bought a Sirrus "Flat bar road bike". Loved it. after a couple years my mileage went up and I wanted to try a drop bar bike. Bought a "Gravell bike" with 105/hydraulic disc. Only time I rode a drop bar bike was on the several test rides while shopping for one. Felt fast, but after 5 miles or so my hands would be so numb I couldn't hardly turn on a bike light. The buyers remorse set in and I thought I had made a huge mistake. The shop gave me a 30 min bike fit when I bought it. I finally scheduled. After the fit, it is like a different bike. Nothing drastic was done either just adjusted to me.
What's funny is after about 6 months of riding the new bike when I get on the flat bar bike it takes me a little bit to get the feel back. Now it feels unnatural to ride with my thumbs pointing in.
