UK Ironman 70.3 road bike or TT bike

Hello people,

I've trolled google trying to find which bike to use for the Ironman 70.3 down in Wimbleball in June. I have seen a few pics of people using TT bikes but without knowning how good they are I cant tell if it would be beneficial for me to use one or use my road bike.
I did the Ballbuster Duathlon last month on my Trek madone as I wasnt sure about getting up the hills on the TT however wish I have used it.

Any help would be much appreciated.

    I'm using a road bike, but then I don't have a choice, although I wil have clip-on bars which should get some use. Watch the video at the top of the page here, http://www.tritalk.co.uk/forums/viewtop ... &start=255, should give you some idea that a TT bike will be OK

    I wish I had a TT bike for it last summer. Definetely are some steep climbs, so plan your gearing accordingly. However, if you're used to climbing on the TT, you'll be faster. Every uphill has a downhill where you can really let loose, and staying low and fast there is worth it. The flat part along the northern edge of the loop, and the long straight sections down the west side of the loop are all ideal for it. Just make sure you're comfortable taking some downhill corners and climbing 4-5% on the aero bars, otherwise you're going to be on the base bar a lot.

    Thanks for the replies guy, ans the questions to ask myself.

    Im going to do a couple of hilly rides on my TT (Planet X Stealth) over the next few weeks to see how I feel, did a 40 miler the other day (fairly hilly) and the times compared to my road bike were about the same so not sure I will benefit until I get more rides in.

    Thanks for the help, will make the decision in a couple of weeks.

    If your looking for a Tri bike that climbs and handles well, try looking at the new Valdora PHX bike. Has had good reviews regarding climbing. Reviews and details can be found at http://bikesales4u.com/ and http://bikesales4u.posterous.com/. PM if you want more info. .

    I think CH made the point that he wouldn't do it on his TT bike, which is a full on, nasty, twitchy bitch of a bike that not only spits him off regularly, but actually follows him around the house tripping him up.

    On a less extreme geometry TT bike, p-x being a good example, it may be a different story.

    I'm comfy on my 'soft' TT bike on just about any road.

    Best answer.... try it and see.
