The world of bike porn is a seductive one with so many shiny two wheeled mistresses eager to release you of your hard earned pennies. Of these the TT bike is regularly one of the most coveted in the world of triathlon as athletes fret about improving their times and look for upgrades and tips to shave those precious minutes from their PB’s.  For our blog this week we look at the need to have one of these machines to do triathlon or in the extreme for those looking to go long and do ironman.  So do you NEED a TT bike to do a triathlon?

Do you really need a TT bike?

So.  Do you need one?  I think we all fundamentally know the answer here without really asking.  Do you want one?  For sure we all want a beautiful carbon TT machine to make us feel faster and carve through the pack to wow our loved ones who patiently wait at the finish line for us to crawl in.  TT bikes are often not lighter and as a consequence not quicker than a road bike.  If you are Dave Scott reborn then this is not the case and there are huge gains to be made from using a TT bike but for the rest of us the reality may not be so cut and dry.

6 key decisions to help decide if you need a TT bike to do a triathlon

To help guide you through this minefield of n+1 bike purchasing we have devised the following set of principles.  Answer yes to all of these and head straight to buy that TT bike you have been pondering over the past two seasons.

  1. Are you planning on tucking into the aero position for at least half of the bike leg?
  2. Can you climb hills comfortably without the luxury of a triple on the front?
  3. Are you confident riding in a crowd?
  4. Does the prospect of not being able to put on the anchors when you need not trouble you?
  5. Do you have another road bike already that you can use as a regular road machine preserving your TT for “best”?
  6. Do you weigh less than 100KG as some of those target bikes have a weight limit?

All of the above get a big fat yet?  Crack on as you could be pedalling away to podium finishes before you know it.  Any of this result in a maybe or a sheepish no then maybe you are better off sticking to that trusty road bike and leaving the TT bikes to the less informed.  We do love a TT bike at Trivelo but we do see lots of folk selling on their pride and joy having covered next to no miles through our site after the reality of ownership turns out not to be such a match made in heaven as they had hoped.  Let us know if this has helped any and if you think differently?  We would love to hear from you with comments on our blog.

Thanks for sharing. I keep battling with this and justification for getting myself yet another bike. Really useful. Answer for me in reality is a No but isn’t going to stop me dreaming.
