Thorn Mercury MK3 Frame - 700c / 650B - Red Imron

The Thorn Mercury Mk3 is a 700c / 650B frame, with reasonably tight geometry, it’s a modern, Rohloff-specific fast touring bike. PLEASE NOTE: the Mercury is designed exclusively for use with the Rohloff EX box hub, it won’t take derailleur gears.
The Mk3 frame is disc brake only and will accommodate 40c tyres (35c with mudguards). For 650B tyres will accommodate 54mm (with or without mudguards). Mercury Mk3 frames are available in 10 different sizes to suit the majority of riders.
There are 5 sizes with long top tubes, these would normally be chosen for use with straight bars.
5 sizes have short top tubes and should be chosen for use with drop bars, or by cyclists who need a more relaxed position with straight bars.
The Reynolds 853 steel frame tubes and Reynolds 725 stays are of the highest possible quality...every tube has been specifically designed for its intended purpose we haven’t just put up with the stock sizes and dimensions Reynolds offer to anyone.
The Mercury is responsive, comfortable and handles perfectly. Several customers have told us it is not just the best steel frame - it’s THE best frame that they have ever ridden! It’s very versatile - at one extreme it can be built into a Rohloff equipped, Drop bar "Sportive" bike - at the other extreme, using our 700c Super Tourist forks and F&R carriers, in trekking guise, it will whisk over 30Kg of luggage along reasonably on good surfaces. A disc brake trekking fork is also available.
All the frame’s fittings, including the vertical, Rohloff EX Box specific ISO disc dropouts, are stainless steel to prevent corrosion.
Drive chain tension adjustment is taken care of via a new size stainless steel eccentric shell , complete with anodised alloy eccentric – any combination of sprocket size and chainring size may now be used.
The frame is supplied with a 1 1/8" FSA Orbit XLII headset, 27.2 350mm alloy Thorn seat post, Eccentric insert and tool.
Does not include: fixing screws, down tube cable stops or bottom bracket.
