This is simply done by turning the barrel adjuster counter clockwise

We immediately took the bike over to a professional cycle shop

The bike is well constructed, gears shift smoothly, the tires are above average, and the seat is very comfortable

We are extremely pleased with our Tommaso La Forma Lightweight Aluminum Fitness bike

Best bike for the money!!

The owner confirmed we had made a great purchase, even stated he could not have beaten the price we paid on Amazon, especially with free shipping! My husband rides the bike 5+ days a week and is very happy with the purchase
