You know the drill…pics first.
It’s got a nice spec on it, with the 2×10 drivetrain. Note that it has fender eyelets on the fork, but no anything cage mounts, and generally fewer rack mounts than a standard Mukluk. It also has standard rear dropouts in lieu of the now-standard Alternator dropouts featured on the 2013 Mukluk.
What’s it ride like? Honestly, it rides like a light Mukluk. It reminds me of my Schweet Mukluk, post modification. The aluminum fork is unnoticeable. Light, effective. The trigger shifters are nice…I noticed and liked them more than I thought I would–I’d definitely make that switch on my Muk when I get a chance. Hydro brakes make perfect sense–as I found when I put them on my Muk. At 28.5 pounds for a Medium, stock build, it’s within spitting distance of the weight of my 2012 Mukluk 2…albeit post modification. My mods include a carbon fork, hydro XO brakes, the 120TPI Husker Dü tires, upgraded seatpost, saddle, etc. I bet if I dropped my heavy-ish Jones Loop bars and threw something lighter on the bike, the weight would be about identical between a modified Muk and a Beargrease.
I didn’t notice any changes in geometry, if there are any. I didn’t get to ride it in mud, snow or seriously adverse conditions, but it felt very familiar and comfortable where I did ride it. The position feels more Mukluk like (upright) and less Pugsley like (traditional mountain bike).
The formed tubing in the frame saves weight over a regular Mukluk, but I can’t say I noticed a change in ride quality. My ride time was pretty minimal, to be fair.
So what are you getting with the Beargrease? A lighter, faster Mukluk. You can do it the hard way, like I did, by building up a custom Mukluk, or you can buy it stock as a Beargrease and be money, and time, ahead. The build specs make sense, and the bike works well.
