Wanting to keep my fat bike around for a while longer I’ve been looking at cost effective ways to improve it. Last year this was new tubeless-ready wheels, and recently it’s been a great-value carbon fiber fork: the On-One Carbon Fatty Fork<\/a>. At about US$250 shipped it’s considerably cheaper than many other options, and it’s geometry just happens to be close enough\u00a0to that of the Mukluk’s original Enabler <\/a>\u00a0fork. (468mm A-C and 45mm offset on the\u00a0Enabler vs 470mm A-C and 55mm offset on the Fatty.) There is a 10mm difference in offset,\u00a0which hopefully will not affect handling too much. Per various online bicycle geometry calculators there should be about 11mm\u00a0less trail with the Fatty.<\/p>\n

Trail calculations, for reference, per yojimg.net Bicycle Trail Calculator<\/a>\u00a0w\/ 559mm BSD and 95mm tire width:<\/p>\n

2012 Mukluk w\/ Fatty: 79mm<\/p>\n

2012 Mukluk w\/ Enabler: 90mm<\/p>\n

2015 Mukluk w\/ Rigid Fork: 94mm<\/p>\n

2015 Beargrease: 94mm<\/p>\n

2015 Blackborow: 87mm<\/p>\n

2015 Pugsley: 88mm<\/p>\n

2015 Moonlander: 88mm<\/p>\n

2015 Ice Cream Truck: 102mm<\/p>\n

On-One Fatty w\/ Carbon Fork: 94mm<\/p>\n

2013 El Mariachi w\/ Fox F29: 82mm<\/p>\n

This ~11mm decrease in trail will likely make the front end feel much twitchier, bringing it just a smidge shortern than my\u00a0favorite XC bike: the Salsa El Mariachi Ti<\/a>\u00a0which has 82mm of trail.\u00a0If my understanding of trail is correct this’ll make the bike a bit twitchier and quicker to turn. Hopefully this won’t cause problems riding it at higher speeds, or keeping a line at slow speeds in the snow.<\/p>\n

This fork is also set up with rear brake spacing — something that’s going away on newer fat bikes — which\u00a0generally means that no special adapters are needed to get the brake caliper to\u00a0align with the front hub. I did have to use two 1.5mm washers to space the caliper over for nice alignment with the rotor (photo<\/a>), but this shouldn’t be a big deal. I’ll likely get some longer IS mounting bolts since the thread engagement isn’t quite enough to make me comfortable. Despite having a straight steerer the fork has a large crown intended to match the On-One Fatty frame<\/a>. This results in\u00a0a slightly awkward step below the headset (photo<\/a>), but with the mostly-black bike I don’t think it looks too bad.\u00a0I’m also not too keen on the orange logos, but in person I think it goes well enough with the sun-faded anodized red\u00a0to not be a problem.<\/p>\n

The originally intended purpose of this fork — front end weight reduction — seems to be successful. After replacement the weight has gone done 1.08 pounds, to 29.74 pounds (photo<\/a>). The original steel Enabler fork, with crown race and star nut, was 1134g, while the On-One Carbon Fatty fork is 637g with crown race, compression plug \/ bung, and the steerer tube cut to length.<\/p>\n

Now to wait for the trails to dry and see how it rides…<\/p>\n

UPDATE: The decreased trail definitely makes the bike twitchier. It’s now a lot harder to ride no handed, but on single track it feels plenty lively and fun to ride. For now I think this is a good thing, although it’ll be curious to see how this pans out come winter.<\/p>\n","protected":false},"excerpt":{"rendered":"
