Nice !
I had a look at that model in the shop the other day , looked very clean and i liked the fact it had rack mount bolts by the rear brake caliper although that fact it has a metal fork was a bit of a let down as i was hoping they would have kept the carbon fork ..........
Strike that just had a google and the spesh allez + trek 1.1 are £50 more expensive and have similar forks .
If you do not like the saddle just go onto
ebay as people are always selling boardman saddles, i happen to like them and even bought one for my virtuoso.
I bought the road comp about 18 months ago on C2W and i get a lot of good comments about the bike ranging from "is it carbon?" because of the smooth welds and "boardmans have a good frame ".
Like other suggested change the white tape when it gets dirty and i couldnt get it clean again .
I think your 1st upgrade should be mudgaurds, something like cruds so you can get out without getting wet ass this time of year , if its not icey there is no reason not to get out there.
Then look at clipless pedals and shoes as they make a lot of difference , again ebay is your friend as you can pick up good second hand shoes + pedals cheap .I prefer to use "MTB" spd rather than road style as i have a fair walk at work from the bike sheds so it easier to walk in the shoes and i only want to run 1 sort of cleat across my bikes.With shoes aldi + lidl have them in a couple of times a year and are serviceable enough .
Most importantly just ride and enjoy it !!!!
