The seat tube cracked on my old hard tail (Big Sur) and I'm now looking for a replacement. I own a duallie but looking to get a different ride. I'm tossing up between Specialized S-Works M5 HT, Kona Primo, or perhaps Salsa Ala Carte, afterall steel is real right? I ride XC, with some technical thrown in, mainly rock gardens a few drop offs of up to 3ft, but in the main tight single track. I love me dual suspension bike (Blur) but looking to mix it up with a stiffer ride for my 6' 2" and 82kg frame. I ride approx. 50kms/week, so I would be grateful for any feedback on these bikes and suggestions of your own. I've looked at MTBR.com and now turning to your help with this next purchase. I'm looking to keep the ride light, less than 10kg. Your feedback is very welcome.
