               Product Details
              
              
              Eerder metaal Quick release Rohloff gear kit Standard works with the standard G-line tires of 2.1" width and narrower.
The Mk1 batch is SOLD OUT , but 9 more Mk2 kits are just finished and contain a nicer centre lock front disc with alu spider, see last photo)
The Rohloff Standard kit consists of:
- Left and right side stainless steel dropouts with integrated derailleur/tensioner hanger, including steel dropout bolts. Fits the Rohloff OEM2 torque arm. Laser cut, stone tumbled and machined 304 stainless steel. With steel chain ring / dropout bolts and nuts included to replace the original alumnium ones.
 - Eerder X Rohloff chain tensioner bolted to the derailleur dropout for easy wheel removal, it swivels back just like a rear derailleur for easy wheel removal and installation, great for maintanance and trail side repairs
 - Eerder low profile Front light mount for Son, stainless steel. This light mount is designed to clear the Son light on the original Brompton luggage frame and the Eerder Full metal Frame on both the plastic Brompton luggage block and the Full metal Bracket for G line. It can also be used for Cateye Ampp lights with the Eerder Ampp light adapter (coming soon)
 - 140 to 160 mm Flatmount adapter to make the 160mm 4 bolt disc brake rotor fit.
 - Sapim Laser Black spoke set (32 + 2 spare 2.0-1.5-2.0 mm butted) for the original G-line rim and nipples using a single / 1 cross lacing (don't use a 2 cross with this small rim and big hub) . Aks your local wheel builder to build a reliable wheel for you. This way we save on material (no new rim needed) and shipping cost and you will have two matching rims in your G line.
 - 160mm XLC disc rotor set, Centerlock front and 4 bolt Rohloff fit rear. These dropouts work with the original 140mm disc rotor, but not the Rohloff hub which requires a 160mm 4 bolt rotor plus the included 140-160 FM adapter. The front Flatmount adapter can be put upside down to fit the 160mm Centerlock rotor. Upgrading to 160mm rotors means more stopping power and cooler running rotors. Both rotors have the same design of the braking surface and spokes.
 - Longer Sunrace bottom bracket cartridge with aluminium housing and cups for a Rohloff compatible chainline. Note: only threaded Rohloff sprockets of 15 t and bigger makes a 54 mm chainline and the narrow splined carrier (SKU: #8540S) a 55mm chainline. The standard chainline of the G line is around 48.5mm (and the Alfine hub +/- 47.25) With the Sunrace BB you get a 52.5 mm chainline. The best you can get, because adding a spacer on the right causes an issue with the folding. The standard splined carrier (SKU: #8540 default on a Rohloff hub) creates a chainline of 57 mm which is not recommended for the G line because of the misalignment of the chain. (52.5mm up front vs 57mm at the back)
 - Optional Rohloff Speedhub Disc CC OEM2 hub including Rohloff twist shifter, cables and shift box and a splined reversible 16t sprocket. Can best be combined with a 50t chain ring or 44t if steep climbs with camp gear is what you're up to. You need 108 links on a 50t and you can reuse the original chain if there's not a lot of miles on it. A few hundred is no problem. If in doubt, just try. If it doesn't skip it's fine.
 
This kit is designed for the 14 speed Rohloff internal gear hub. You can check the difference with the Alfine 8 hub with the link below:
ritzelrechner.de Rohloff 14 vs Alfine 8
                  You can click on the window with the gears displayed to check or customize the settings. The top one is Rohloff and the bottom window is the Alfine 8. 
                
 
                
                  You can see that both gear hubs have three gears above the 1:1 gear (5th for Alfine and 11th for Rohloff) and the Alfine has some more spacing between the gears. The Rohloff has three more gears at the bottom and a smaller spacing between the gears, resulting in 10 gears lower than 1:1 ratio vs 4 gears lower than 1:1 for the Alfine 8. In order to have the gears better spread for the 20"wheels of the Brompton G line the Rohloff hub needs a smaller sprocket. I consider a 16 teeth sprocket ideal, combined with a 44t chainring for the average rider and a 50t for speed devils.
