What's a faster race set up?

I've been wondering which will be a faster set up for this seasons flatter races? Both have the disc on the rear but which is a faster front? I didn't buy the spinergys to race on but reckon it could be a fast wheel on the front but the cosmic carbon is a quick wheel as well. Any opinions would help thanks.

Time to accept facts

Ok so this season was due to begin a couple of weeks back at the Clumber Classic duathlon, entered and DNS. Next up should have been the Fleet Half Marathon, entered and DNS. Next race should be the London Marathon, entered and you guessed it...........its going to be another DNS. There is a bit of a pattern going on here and its not very good! When I first injured my knee in Lanza back in Feb I thought I would be back in time for London but with only 4 weeks on Sunday until race day its time to give up that hope/dream that I will be fit and ready to race. I am actually doing a little running but not a chance of any distance or speed. I feel at this stage its far more important to avoid further injury and try and recover for the European Championships for the GB Age Group squad in June and the Antwerp 70.3 in July. Being an athlete really sucks sometimes I hate injuries.

Champions bike for sale!

Ok so if you've seen my previous post you will be aware I now have a new time trial bike from my sponsor this season. As a result I don't need my other time trial bike which was the very machine that took me through last season to become the Yorkshire and Humberside Champion. This is in very good condition as you can see from the pictures. Its been fitted with a brand new set of michelin ironman tyres and is ready to go. I'm looking for £900 for it. Also I've popped a quick pick on of my TCR with my retro wheels I picked up recently for a bargain price. Nice set of wheels for training on and despite the age I think they still look cool.

Ok, so a quick update, total hours training last week...........zero, hours training the week before.........zero, hours spent painting the house before it went on the market 18-20. So i've been a bit busy lately, but it didn't matter much as my knee is still not fixed. Finally got my arse into gear and picked up the new bike from Paul and Lisa at http://www.hilderthorpecycles.co.uk/ / Cyclelife. So Friday was the first ride on it to sort out my position. After a 20 mile loop I went back to the shop and swapped the stem from my Giant Trinity TT bike which is now in the shop for sale. I fitted the stem and then today (Sunday) did 26 miles on the turbo trainer so I could finish tweaking it, only changed the saddle position by moving it forward on the rails. I am now sure of the tri bar length and will speak with Paul to get about 2 inches taken off the length so the bar end shifters are closer and that should be it all set up. Initial thoughts after Friday's road ride are its a nice ride. It corners well and descends nice and steady. Haven't climbed to hard on it yet due to the knee injury as its still not ready to be pushed hard. Its a full carbon frame with full carbon fork and topped off with full SRAM Red groupset. So what are your thoughts, do you like it, be honest with your comments.
