Eerder metaal Mk3 Rohloff gear kit Standard for Brompton G line without light mount, spokes and discs, 4 kits and more, 82 discount
Product Details
Eerder metaal Quick release Rohloff gear kit Standard works with the standard G-line tires of 2.1" width and narrower.
The Mk3 version of the chain tensioner now features a black anodised pulley cage (arm). The stainless steel base with the static pulley is still brushed RAW stainless steel.
Note: not all the photos are updated, some show a non black cage
The Rohloff Standard Mk3 kit consists of:
- Left and right side stainless steel dropouts with integrated derailleur/tensioner hanger, including steel dropout bolts. Fits the Rohloff OEM or the OEM2 torque arm, the choice is yours depending on the hub you allready own or just your personal preference. I stock both hub versions and one can always change the torque arm from OEM to OEM2 and vice versa. One is not better than the other. The dropouts are laser cut from 304 stainless steel, stones and steel balls tumbled and machined. With steel chain ring / dropout bolts and nuts included to replace the weaker original alumnium ones. Note: the OEM version is needed in case you want to electrify the gear shifting with a dynamo powered Sternshift kit. https://www.cyclingabout.com/electronic-shifting-f...
- 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
- 140 to 160 mm Flatmount adapter to make the 160mm 4 bolt Rohloff disc brake rotor fit.
- Longer Sunrace or Neco 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)
- Hex key Skewer 146 mm long for the 135mm wide Rohloff hub plus the 5mm thick dropouts. Just the perfect and minimalistic skewer for a Rohloff hub. Not with a quick release handle so you need to carry a 4mm hex key to take the Rohloff wheel out. Also a bit less theft friendly. There's an option in the menu on the right to change to a quick release skewer made by Hope Tech UK in the right length for this hub width - dropouts thickness combination of 145mm .
- Optional Rohloff Speedhub Disc CC hub (OEM or OEM2, I will match it with your choice of dropouts) 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 (I prefer the versatility of the 44t chainring). 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 compare the difference in gear ratios and band width with the original 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.
