I have my new TT bike (thanks again to my man) and I bought the same saddle as I use on my raod bike.

I think the make of the saddle isn't so importantant as the position of it.

Because a TT position will put your bars lower in relation to your seat height, then check the position of your seat - it is likely that all you should need to do is tilt the nose down a tad, rather than change the whole saddle.

Good luck
