Description

Nathan Halahan is very good at riding little bikes on big piles of dirt, and the S&M Rambler is the frame built to give him the confidence to do it. Nate's signature version runs a 74.25° head tube angle and a slightly shorter rear end for riders who like that feel.

The frame is built from butted Thermal-X tubing with a 5 inch integrated head tube, a mid bottom bracket and an integrated seat clamp. Welded 990 mounts on the chainstay and 14mm 4Q-Baked dropout slots round it out, with no gyro tabs, all up at 2.45 kg.

Features

Nate Halahan's signature trails frame. A 74.25° head tube angle and a slightly shorter rear end, set up the way Nathan Halahan wants it for big dirt.
Butted Thermal-X tubeset. S&M's butted tubing keeps the weight down to 2.45 kg without giving away the strength a trails frame needs.
Adjustable 13.75 to 14.5 inch rear end. 14mm 4Q-Baked dropout slots let you slam the back wheel in or run it long to suit the way you ride.
Welded 990 chainstay brake mounts. Run a rear brake down low and out of the way, with no gyro tabs cluttering the head tube.
Two top tube lengths. 21.25" and 21.5", both with a 9.25" standover, an 11.6" bottom bracket height and a 71° seat tube angle.

Top Tube Length - 21.25

Frames are sized by top tube length. Start with your height, then let riding style decide where in the range you land.

Rider height	Top tube
147 to 157cm	19.75 to 20.25"
157 to 168cm	20 to 20.5"
168 to 175cm	20.25 to 20.75"
175 to 183cm	20.5 to 21"
183 to 190cm and up	20.75 to 21.5"

The height bands overlap on purpose. If you land in two of them, riding style breaks the tie: longer for flow, trails and transitions, shorter for technical street and park. Plenty of riders, pros included, deliberately ride longer than a chart suggests.

How to measure

Top tube is measured from the centre of the seat tube to the centre of the head tube, so it is not the length of the tube you can see. Measure your current frame that way and compare.

Size up for stability through trails and transitions.
Size down if you want the bike quick and twitchy for spins and grinds.
Top tube is fixed once you buy, but chainstay length, stem length, fork offset and bar position all change how the built bike feels.
