Great looking ride! I'm not sure about a smaller small chain ring but you could either go with a compact crank or try a 28t cassette. I'm running a 28t in the rear and can get over all the climbs that I ride without a problem. Soon I will be riding some organized rides with about 11,500ft and 13,000ft of climbing. For those rides I will use a Rival long cage derailleur and something like a 32t cassette. I'll have a separate chain for that set up, obviously. You may need to loose a link or two on the chain but that is much easier to do then needing to add
My SLR01 is now finished. The weight is a hair over 15lbs. Mainly due to heavy Dura Ace skewers which are quite porky. I'll stick with them as I tried some of the other lightweight offerings and was never really happy. They creaked and didn't seem to hold up well over time. My ocd also causes me to possibly over tighten the skewers and the DA ones fix that as they slightly release pressure as you close them. I could drop more wight with SRAM Red but at this point it's not worth it. I also went back to my 3T 110mm stem and Ergosum bar. Although the PRO Stealth EVO stem and bar combo felt stiffer I much prefer the feel and fit with the Ergosum bar, especially in the drops. If I had the drops of the 3T bar on the carbon EVO, it would be a keeper. Not a fan of ergo bends. The ride and handling is superb. Great on climbs and even better on descends. I've been riding my CAAD8 over the past week and although it handles awesome and is a plenty stiff bike for climbing/sprints its not something I will choose for longer rides. SLR01 feels like it's on suspension
Here is the final set-up photo I snapped with the phone. Hope to have some time soon to take some decent photos.
