I've ridden my 'lugi in all sorts of conditions, ranging from muddy slop to snow and ice to sand to endless tarmac. It's worn deep carbon tubulars, handbuilt GP4s, and modern Campy clinchers. Currently outfitted with 23c Panaracers, I've tried it with Challenge Grifo tubulars, Schwalbe Ultremos, and some 28c touring skinwalls. With each iteration, the riding characteristics changed a bit, but it's always remained light, nimble, and fun to ride. As most reviews have noted, its IBIS roots are very noticeable in its downright... huckability offroad. With the right wheel and tire choice, skilled technical riders will find it to be a joy. This quick handling may not necessarily translate to better racing, however. With not a little horror have I witnessed my poor 'lugi crashed within minutes of loaning it to a friend. But I'd rather have a bike that I can grow into, rather than one I'd outgrow...
Very large or very strong riders might find the frame insufficient in rear triangle stiffness, at least when compared to the overbuilt bikes in the Ridley, Empella, and Stevens universe. Personally, I think it strikes the perfect balance of lateral bb stiffness and vertical compliance. There are very few true racing cross bikes that I wouldn't mind riding in a brevet or a fast century, but the Hakkalugi does just fine.
As a pure road bike, well, it's not ideal. Novices probably won't notice the difference, but the high bottom bracket -- while terrific for racing and high speed offroad maneuverability, is not your friend when cornering. But then again, I don't anticipate too many folks using one as a dedicated crit machine.
I really like this bike, so much in fact that it will be my ride of choice for this year's Great Lakes Randonneurs Brevet #1 on the first of May. For cross use, I really can't imagine a more ideal bike for my use. It's an absolute joy to ride and race. On the road, the Hakkalugi is far more comfortable than it deserves to be.
