I have an '05 larkspur, and have been very happy with it. I've put on about 3500 km on it so far (I split my time between Calgary and Toronto these days, and I only ride the larkspur three seasons, so that's why I have the low mileage). I've even ridden on it for a century . It's the first Al frame I've owned, and I have noticed that it is a bit harsh (I tried swapping out the suspension post - bad idea), but the suspension post seems to work for me.

In terms of components - I've worn out a chain and a set of brake pads (I ride rain or shine, in a city where going downhill is a regular occurance). I've also loaded it up with 50 lbs on the rear rack, with no major handling problems. It's given good service on good pavement, bad pavement, dirt, mud, sand and gravel - with no problems. Only freezing rain, snow and ice have me switching to my MTB. Bottom line is that it is a pleasant bike to ride with the ability to take just about any conditions - though I prefer a smaller, more MTB frame for riding on snow and ice.

IIRC the Larkspur is cheaper than some of the other options - the Dew Deluxe is definitely prettier - but theft can be a concern depending on where you live...
