Very well done. The new Addict SL is so much lighter than the version it replaced. I always wondered why we don't see more of these fantastic frames on this forum. 10 years ago the original Addict was a starting point frame for all weight weenies. The revised Addict is so much cleaner with the internal cable routing and semi aero profiles. I just love it.
What are some noticeable differences on ride quality and fit when compared to your retired RC build?
With 250mi on my new Addict now, I can happily report that all is well. The fit is good (benefit of sticking with essentially the same geometry) and the ride is pleasantly taut. When I (finally) find some fitness, we'll see how it ascends and descends.
The ride on my new Addict is more compliant the vast majority of the time. (My old Addict wasn't unruly, but it didn't have much "give." I have a funny memory about my first ride with it - felt like the tires were pumped up to 500psi!) My new Addict has a 27.2 seatpost vs an ISP, which is allegedly supposed to contribute to a more compliant ride. Furthermore, the chain stays are shaped differently and look like they're designed to flex up and down not side-to-side. They're still oval-ish, but they're squared off on the top and underside now.
I say it's more compliant most of the time because my new Addict acts very differently on some poor road conditions where there's very regular perpendicular cracks in the tarmac (maybe a bike length or two between each). The bike seems to get out of sorts when the bike is rhythmically hitting these one after the other - boom, boom, boom. I wonder if the "magic" up/down flex built into the chain stays gets out of "time." It's an oddity, since the ride is so much better otherwise.
For my new cockpit, it's a 100mm Extralite stem and 40cm x 31.8 Lightweight bar. I feel more flex sprinting in the drops than with my old cockpit (90mm Extralite and an old 40cm x 26.0 Kestrel bar). Not sure it matters, but I feel a difference.
While I'm talking about the cockpit, my new stem is longer but my LW bar has less reach (79mm vs 84-85?) so it's taking a bit of getting used to - the flats are 10mm further away than on my old bike due to the longer stem, but the shorter reach on the LW bar moderates the distance to the hoods and drops. As a result, I'm less hunched over in the drops and more stretched out overall, but my elbows are still nicely bent on the hoods.
Riding with Power for the first time is fun. I've got a lot to learn (!!!), but a riding partner with loads of experience is shepherding me through the learning curve. I hope that I don't ride scared, like I did many years ago when I first started with HRM. I was afraid of my shadow - every time my HR went up, I backed off the pace.
