it helps, especially once you already have an engine
once you are riding at 30kph avg, deep section wheels do make a difference - they keep speed really well and maybe add 1-2 kph
my ebay special sram s30s have just bit the dust, and the vision tri max pros (£500 discounted to £250 3 years ago also have just given up the ghost - not surprised as I have hammered them - 3 years of training, winter rides and 2 IMs) the free hub / cassette was wobbling seriously today but they got me round the southern sportive - 192k and 2 something meters of climbing. - thought of bailing at 40k but they kept going
so I too am in the market for a nice set for the road bike, and a winter / training set for the tri bike
joddly - I understand a bit - lost my nose clip in the first metre on the Vit and spent the next 200 feeling like I was drowning as water washed up my nose - I actually started to head for the kayaks twice, but there were too many swimmers in the way, and it was easier to keep going. I had to have serious words with myself, and only just decided to carry on.
not having much target makes it very easy to not HTFU....
sounds like you are gonna go back next year and smack it? or just try to swim in big seas?
