Can one bike do it all?
I am 30 years old and have taken part in my first sprint distance triathlons this year using my trusty Merida Ride 77. Despite being a relatively poor swimmer I have really enjoyed the training and events and wish to build up to a half iron man in summer 2016. I'm not going to be on the winners podium any time soon but to cover this longer distance comfortably I need to upgrade the bike. I have a budget of around £4-5k but would not want to spend all of that on a tri specific bike as I also take part in group rides and sportives that often take in a bit of climbing.
I am wondering whether or not to invest in a higher range aero bike such as the Cervelo S3, Canyon Aeroad CF SLX, Boardman Elite Air 9.8 or higher end Giant Propel that could potentially do both jobs with a bit of change in set up and clip on aerobars, or to go for 2 entry-mid level bikes such as a Dolan Scala and Tuono. Any thoughts or advice?
