Hi guys I've been cycling a while now on my old appollo TDF100, soon I'l be upgrading through cycle to work scheme. This year Im planning to ride some sportives namely the wales velethon and the Tenby velethon, Im looking a 3 bikes for my upgrade, these are 1. giant defy 0, 2 Cube peleton race, and 3 Felt z75. all are under 1K and have compacts groupsets, has anybody got any advice or ridden these. I'll try to ride all 3 before I buy, but is there any concerns around reliability etc to take into account. Cheers..
