I'm looking to upgrade my '05 Specialized Allez to a new bike in the $2,000 range. I'd also like to support my lbs. My favorite lbs can hook me up with the Kona Zing Deluxe for about $2,100. Another lbs can get me on Jamis Ventura Elite for $1700. The Kona is full carbon, while the Jamis is a mix - but also is Ultegra vs. the Kona's 105. Any insight or advice on either of these bikes is appreciated. Any suggestions for other bikes in this price range would also be appreciated as well. I am a recreational rider and I ride about 50 miles per week and I ride a handful of centuries in the summer as well. I'd like to stay 105 and up component wise. Thanks.
