As a background, my interest in cycling is almost exclusively for practical reasons - commuting to work, towing the kids around to the park, etc. Not into it for the sport/racing/fitness etc. So my rig is a ~14 kg flat bar commuter with the works (and a hub gear); slow, but gets me there every day rain or shine.
On the weekend I met up with my brother and some of his friends in the Barossa Valley after they did the BUPA Challenge (if you saw a guy in a pink tutu, that was my brother). Anyway, he loaned my his bike for a loop through the hills - we did about 35km through Tanunda, over Menglers Hill, Angaston and Nuriootpa.
The bike is a Look 585 with SRAM Red and weighs about 6.5 kg.
I knew it would be faster and more efficient, but honestly I was completely blown away by how much more efficient it was, and how quickly it would respond to acceleration. Ergonomics was OK for something that wasn't set up for me - probably a size too small, though it did feel very stretched out on the hoods. Shifting was OK, though the front D was a bit recalcitrant and crunchy. The saddle was very comfy despite looking like a medieval torture device (Selle SMP composit). Decently stable on the downhills. Brakes were so-so - I much prefer my over-servoed disc - but never needed to use them in anger. Probably the main issue there was just accessing the drop bar levers.
Overall a very fun experience, I didn't walk away sore and didn't embarrass myself/get dropped.
Yeah, back on the commuter today was a grounding. It accelerates in the same way that pulling a car with an occy strap would - ie, eventually it's going a bit faster. The LOOK was just instantly going faster as soon as you put weight on the pedal.
Speaking of pedals - road pedals can get bent. SPDs for life.
So, when are you getting a road bike?
When I could either justify it, had space to put it or time or reason to ride it... It was a fun experience but it would make as much sense as putting a Ferrari in the driveway.
I'm curious to know if there is a dominant reason for the speed difference, or is it just a sum of all the parts combined (drivetrain efficiency, weight, rolling resistance, aero position, frame stiffness). What makes the biggest difference and what makes the least?
It's everything - aero, light weight, all the parts and pieces put together. But the light weight is the biggest difference, along with the drivetrain efficiency and aero, compared with a non-road-bike. On a road-bike, you were probably a lot more tucked down as well - which also makes a difference
Just makes a road-bike really fly. And you riding a heavy bike, you are used to that, so putting you on a light weight bike and the feeling is hey, this is pretty good!
But at the same time, my road bike, I put a different set of tyres on it, and it was like riding through superglue - they were sort of like all-weather tyres. They were so slow in comparison - swapped them off really quickly.
