Feb 1, - I thought I'd impart a little bit of advice on an aspect of bike applies for other Shimano hub gears; select the 'marked' gear). . start, or maybe riding with the lock ring loose caused some internal damage. I bought a Cube Hyde pro with a Nexus 8 speed hub and the gears started to slip, it was infuriating.
Shimano sells a relubrication kit for grease-lubricated hubs. Still, many hubs are inadequately lubricated as sold, and frequent failures of grease-lubricated hubs due to water contamination have been reported in wet climates -- see photos here.
Better lubrication sidesteps this problem.
It is best to add oil to the lubricant regimen when rebuilding a hub, so it gets a clean start and you regrease the bearings at the same time. This is desirable even with a new hub.
Follow the example shown in the photos from Aaron's Bike Repair near the bottom of the page, after you get past the 700cc road bike photos of rusted parts at the top.
Use ezip trailz bike of waterproof marine grease as used in boat-trailer wheel bearings for the bearing assemblies -- this keeps water out and oil interna, use lightweight white lithium grease for the gears, especially with modern wide-mouth hubs that hold oil poorly; Phil Wood Tenacious Oil 8 speed internal hub bike the pawls and in the shell to slop around and get to where the grease didn't reach.
An internal-gear hub with a 8 speed internal hub bike axle may be re-oiled by removing the pushrod or indicator spindle and squirting oil into the end of the axle. Plug all the holes with machine screws between oilings. On a hub which doesn't allow one of these tricks, you could install a Sturmey-Archer oil cap.
You do need to disassemble the hub so you can clean out the metal chips. A simpler but less convenient sped is to unscrew the left bearing cone bike costa rica squirt oil in past the left end of the axle. Oil can accumulate on the hub shell, and can become a bit messy, but, big deal. On the other hand, if used to excess, oil can run down the hjb onto the rim, soften the brake shoe rubber and make a rim brake squeal and grab.
This is hazardous in a front wheel, but the internal-gear hub is in the rear wheel. Cleaning the oil and brake-shoe rubber deposits off the rim restores brake function. Old Sturmey-Archer coaster-brake 3-speeds have an oil fitting, but other hubs with a coaster brake require a special high-temperature grease for the brake shoes. Some hubs use a different grease for the rest of the mechanism, so the pawls don't stick.
A coaster brake in an internal-gear hub is, all in all, a poor idea because of the wear particles it generates, and because you can't use oil lubrication.
Oil lubrication may cause problems with a drum brakeby seeping out past the bearing and spwed the brake shoes. Phil Wood 8 speed internal hub bike Oil stays in place better than most other oils.
This will prevent oil from leaking into the drum. Place something under the rear wheel to catch the drip, especially if you have just oiled the hub. Shimano Rollerbrakes supplied with 8 speed internal hub bike hubs are outside the hub shell, avoiding the contamination problem.
These use steel brake shoes inside a steel drum and require periodic lubrication with special high-temperature grease.
Internal-gear hubs typically use a single sprocket and single chainwheel. The chain is held in place by moving the hub's axle forward or backward in the dropout slots until the chain is just barely 8 speed internal hub bike, or a bicycle with vertical dropouts may have an eccentric bottom bracket. As the chain wears, it lengthens, and it is more likely to fall off.
It must be readjusted periodically. A freewheeling hub hhub 8 speed internal hub bike a fixed-gear or coaster-brake hub -- may use a chain tensioner with a pulley instead. More detail is on our page about derailerless drivetrains.
The axle is part of the gear train of an internal-gear hub. You can check this out for yourself. If you hold the hub shell or rim when the hub is not installed on the bicycle and turn the sprocket, the axle also turns -- backward if the hub's drive ratio is lower than 1: With most hubs, special anti-rotation washers keep the axle from turning when the wheel is installed on the bicycle. These washers engage flat nick bike on the 8 speed internal hub bike, and have tabs that niternal into the dropout slots.
Different washers fit different models of hubs and dropout-slot widths. Many newer hubs attach the shifter cable to a pulley that rotates around the hub's axle, between the right dropout and the sprocket. Depending on whether a bicycle has horizontal, vertical zpeed reversed 8 speed internal hub bike dropouts, different washers are needed so the shift cable can approach from the front of the bicycle. Follow the instructions for each hub.
