Surly MidNight Special 27.5"/28" frame kit - black | 40 mm | L | 27,5" (650B), 28" | 12 mm Thru Axle

Product Description

The MidNight Special 27.5"/28" frameset from Surly is the ideal setup for your touring & trekking, gravel, cyclocross, and road adventures. The frame and fork are made entirely of Surly 4130 CrMo steel, providing a stable balance of strength and durability. With clearance for 1x, 2x, or 3x chainrings, you have the flexibility to adapt your drivetrain. The maximum tire size of 700 x 42 mm or 27.5 x 2.35" lets you ride across a wide variety of terrain. A high clamp front derailleur mount (28.6 mm clamp) makes derailleur installation easy. The frame supports flat mount brake mounts, allowing for clean integration of disc brakes. This frameset is the perfect foundation to conquer roads and your local trails. Whether cruising through the city, riding country roads, or exploring off-road, the MidNight Special frameset is your reliable companion.

Note:

When choosing your frame size you should take into account that Surly does not measure the seat tube specifications to the end of the seat tube. For frames with struts on the top tube, this is measured from the middle of the bottom bracket to above the struts. For frames without struts, measure from the middle of the bottom bracket to the top edge of the top tube.

  • 5 out of 5 stars
    by Andrei V. on 19.07.2023 item: black | 40 mm | XL | 27,5" (650B), 28" | 12 mm Thru Axle

    The only wish is a completely horizontal top tube (it has a tiny drop to the back in the size 58).
