No offense, but if you've been riding for six months, be you probably aren't putting out the same power as people who've been cycling for many years. Even if you really and swam for years. Specificity.
Climbing it's all about watts to kilograms, on the flat it's mostly watts to air resistance. A $200 skin suit will save you more time than $2,000 wheels. The other cyclists probably put out more power (because they've been doing bike race discussion workouts for years) and have better aerodynamics, mostly because of posture.
