Talk to me about wheels, please

[williaa68]

My local bike shop, who have always seemed pretty good and straight, have told the mrs ahead of her first Ironman 70.3 in a couple of weeks that the best upgrade she can make to her existing bike (a Meek 2k Poggio - cost about £750 i think) is to the wheels. They have various sets on sale but have suggested a carbon set from Vision for about £500. I know very little about such matters, will new fancy wheels make much of a difference? The wife is an experienced ultra-marathon runner but relatively inexperienced in triathlons but has been training fairly hard. All thoughts and advice much appreciated. Thanks in advance.

thanks - that's all very helpful.

Thanks for the advice. So she bought the wheels (vision 42's) and did the 70.3 today. She seems pretty happy with her bike time - about 3.15, particularly given the heat - someone told me at the end their bike computer registered 38 degrees on the second leg of the bike course. Very impressed with the organisation and some of the kit there was amazing - i was talking to a South African bloke this morning who said he bought a bike instead of a Porsche as his mid-life crisis. I had to confess to buying a Porsche but I think it was cheaper! Also interesting that the gender mix between tris and marathons / ultras is so different - 16% of competitors this morning were women, most marathons these days it is closer to 40. Roll on Wales!
