Last few newbie questions... (coaster, drum, S-RAM/Nexus, etc...)
I am doing some research and have compiled my final questions. If you
can shed some light I would be greatly appreciated. 1. Coaster Brakes - These are available on the SRAM7/Shimano Internal hubs. Do these require any maintenance? How long do they last? For general parks/bike paths with very few big hills would a coaster brake be enough? 2. Drum Brakes - Similiar questions related to the Internal Hubs. Do these require any maintenance and how long do they last? 3. I've noticed that once people ride both the Shimano Nexus 7 Internal Hub and the S-RAM7 Internal Hub it's a no contest and people prefer the SRAM. The SRAM as people describe it feels more efficient and rear wheel removal seems easier (I imagine with a coaster brake the SRAM would be the easiest internal hub to remove the rear wheel.) Is their anything at all that makes the Nexus7 seem better? More reliable? 4. If the SRAM7 is the preferred internal hub, why is everyone (trek, electra, reliegh, van dessel, etc) using the Nexus7? The only bike company I've found who uses the SRAM7 is Burly (Simple 7). 5. Besides cost obviously (and my guess is also weight) - are their any advantages of a 3 speed hub over a 7 speed? |

For general parks/bike paths with very few big hills would a coaster brake be enough? Coaster brakes are low maintenance, but a little odd until you get used to them. It takes a good coaster brake to be able to lock the rear wheel; and, while you should be using the front brake as a primary brake, you want the rear brake to work as well as it can when the front brake is unavailable. 3. I've noticed that once people ride both the Shimano Nexus 7 Internal Hub and the S-RAM7 Internal Hub it's a no contest and people prefer the SRAM. The SRAM as people describe it feels more efficient and rear wheel removal seems easier. The SRAM is also wider ranged, but there is a new eight-speed Shimano hub gear with a wider range than the Nexus 7. 4. If the SRAM7 is the preferred internal hub, why is everyone (trek, electra, reliegh, van dessel, etc) using the Nexus7? Much cheaper in bulk? -- David Damerell Distortion Field! |

How long do they last? Pretty long. For general parks/bike paths with very few big hills would a coaster brake be enough? You should also have a front hand brake...don't put all of your eggs in one basket! Coaster brakes make it very awkward to start up, because you can't easily rotate the cranks to a good starting position. 2. Drum Brakes - Similiar questions related to the Internal Hubs. Do these require any maintenance and how long do they last? Durability is similar. 3. I've noticed that once people ride both the Shimano Nexus 7 Internal Hub and the S-RAM7 Internal Hub it's a no contest and people prefer the SRAM. Not everybody does. I would prefer the SRAM for hilly terrain, because it has a wider range of gears, but I'd prefer the Shimano for flatter/rolling terrain because the gears are spaced closer together. Wheel changes are easier on the SRAM, but the shift linkage at the rear axle is much less vulnerable to damage on the Shimano. I also like the Shimano RapidFire shifter better than a twist grip. 4. If the SRAM7 is the preferred internal hub, Again, not necessarily so. why is everyone (trek, electra, reliegh, van dessel, etc) using the Nexus7? The only bike company I've found who uses the SRAM7 is Burly (Simple 7). These bikes are all made in Asia, so it shouldn't be surprising that they favor Asian parts. 5. Besides cost obviously (and my guess is also weight) - are their any advantages of a 3 speed hub over a 7 speed? Nope.

We build lots of SRAM Seven wheels here and yes, riders seem to like those better generally. CB are virtually maintenance free under normal conditions- We haven't seen anything wanting in ten years . So far so good. Some riders (me) find the CB's inability to backpedal at a stoplight annoying. Cable routing is low on the bike for both the Seven control and the drum brake cable. Some riders ( you know who you are - always riding in the curb and in the slush and slop at the side of the road) need to pay attention to cable lubrication. Given enough salt, even low grade stainless wires will swell with oxidation. We have exactly one customer with that problem who gets new cables every couple of years. Shimano trade practices "You put Record on your race bikes and you'll never see another XT derailleur'. Larger forces are at work here. Three speeds are cheaper than seven speeds. If you can swing a SRAM Seven wheel for your bike, get it over a three speed. About $70 more for the hub with controls. A built Seven wheel runs about $315 with controls and sprocket. Add $30 for either brake. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |
