Gravel/Endurance

Midnight Special is a road plus bike designed to provide comfort and speed on those all-day rides that extend well beyond fresh pavement. Midnight Special shines on pot-holed, deteriorating pavement and the occasional long stretch of gravel. Its 650B road plus tires eat up road chatter and absorb all the bumps in the road like the champion it was designed to be. When it comes to road bikes, we just want to toss a few bananas into our pockets and see where the road takes us. We seek out varied surfaces on our rides and frequently go from pavement to gravel to worse pavement. Midnight Special allows us to accomplish all of that quite comfortably. - Higher volume tires allow better fine tuning of tire pressure on varying surfaces and create a wider contact patch for increased traction - Modern road standards like flat-mount disc brakes, 12mm front and rear thru-axles, and a 44mm head tube - Clearance for 650B x 60mm or 700c x 42mm tires without fenders (650B x 50mm or 700c x 38mm with fenders)

And, Rival hydraulic disc brakes deliver ruthless stopping power with precise modulation and a lightweight design; everything you want in a race-ready braking system.

Taking their love of riding drop bar bikes off-road to its logical conclusion, All-City presents you with the Gorilla Monsoon. A sweet beast whose only limits are your imagination and will power. They've taken the capabilities of their famed cross bikes and built a Monster. All-City's most densely featured bike ever, fully hitting everything on their checklist for a steed that can take you far into the unknown in comfort, style, and elegance. Want to do mixed pavement and single track rides? Put in long days off-road? Do some fire road touring? Camping? Ride across the continent? No problem. Peep the features: Front and rear thru-axles, front and rear rack and fender mounts, compatibility with Surly-8 and 24-Pack racks, stealth dropper post routing, 27.5 x 2.4” tire clearance (650b x 48 with fenders), signature All-City dropouts, E.D. coating for rust prevention, and three water bottle mounts. The Gorilla is made from All-City's 612 Select tubing and features a lovely bi-plane crown steel fork. They believe that nothing soaks up bumps or is as durable as a high quality steel fork. For on and off-road touring duties, it is the jam. Some of you will want to throw 650b x 47c’s in it and that’s cool. The resulting slightly lower BB gives the bike excellent manners when riding with a load and is fully endorsed by us. If you want to run a 700c tire the max is a 42mm tire which will raise your BB by 8mm. 700c x 38 keeps the BB about the same. As for building it up, there are three cable mounts on the downtube, giving you the option of adding a front derailleur or a dropper post. Here’s the max ring sizes for each setup: 1X = 38T, 2X = 28/42, 3X = 26/36/48.
