Hi! Im new to this forum and even newer to Triathlons!
Im planning to buy a bike, but Im not sure if buying a Road bike or a Triathlon one.
Some info that might be important for the decision:
+The longest TT Im planning to participate is Ironman 70.3, most others are mainly sprints
+I live in a country/city with lots of mountains, so that would be the comon training ground. Off course I can find spots with no mountains as well though.
Ive heard also that is possible to:
+Buy a Road bike and just change the Steering to the TT, but I understand that the whole reason behind the TT bike is the body position to "save" legs for the running
+Buy a TT bike and change the steering to road, dont no if this has a con.
I've ridden nothing but road bikes until a few weeks ago when I picked up my first tri bike (a Felt B16). I absolutely love my tri bike but I can already tell that climbing on it won't be much fun and that group rides will leave my wrists hurting due to the lack of hand positions where I can still access the brakes. If you plan on doing any group rides or really enjoy climbing I would stick with a road bike. If you plan on training almost exclusively on flat roads or on a trainer and all your events have relatively flat bike courses then the tri bike will be faster.
It is possible to change your road bike to a tri bike with aero bars and a different seatpost. However setting up a road bike as a tri bike will ruin your road bike fit and you'll have to change back and forth each time. You could also install the Red Shift system that makes this switch easier. (Redshift Sports: Free Shipping & Returns. 100% Satisfaction Guarantee)
I've seen some people buy a tri bike and try to make it a road bike but that is very difficult as the steeper seat tube completely changes the geometry of the bike.
Thanks for the heads up on the redshift aerobars! I plan on using clip-ons on my S1 this year, and these look like a great option for me. Combined with an extra seat rail clamp for the Cervelo 2-pos post, swaps from road to tri fit will be super easy and repeatable.
