Other than that the bike was ok. That was two years ago and I'm still riding that sucker. :-)

Having said that, I do enjoy riding my Surly Disc Trucker more. I'm about same speed on both bikes. Go figure - probably the drop bars vs flat bar on the specialized Sirrus give me better aerodynamics. No idea.

Besides the pedals (one day I might put titanium eggbeaters on it), I have optimized everything else to save weight. Added carbon handlebars, carbon stem, carbon seat post, titanium rail bicycle seat, carbon rims, riding tubeless... I don't think I've gotten much faster than the original bike configuration ;-) I don't think adding the titanium eggbeaters will change that ;-) but when it comes to strength of the material I have no fear of carbon.
