I have experience of the Boardman, 2009 /10 vintage. A very light, well built, well equipped fast commuter. Agile,
good great brakes, stiff frame, great value. Equipped with 28mm tyres originally, I put 25s on mine and thrashed it on roads. Others put 35mm cushions on theirs and rode them on towpaths and paths. What's more, it is bought by people on C2W schemes and they use it a few times and sell them on
eBay a lot, so there are loads out there, but they do tend to hold their money. For that reason, although you're getting a great bike for the money new, they are good value secondhand, with the usual pitfalls to buying. You can find the one that's been in the garage since last August, or you might find the one that's been ridden to death!
I have no experience of the Spesh, but loads of folk on here have them and recommend them, so there must be something in that! The Crosstrail has a suspension fork which will add weight, but increase range off road. Pop along to
Evans and have a look. Equipment levels won't rival Boardman, but you're buying into a "Ford Mondeo" style brand so won't go far wrong.
Sit on both back to back if you can. Bikehut is unlikely to let you go further than the water bottle display on a test ride, but at least you'll get a feel for the weight etc.
