120mm spaced internal gear hub? (more than 3sp)
Per Sheldon:
http://sheldonbrown.com/harris/shimano-nexus.html I want to run a 8sp internal geared hub, preferably the Alfine or Nexus Red Band, but it looks like I'm going to have trouble getting the frame I want in 135mm spacing (despite what pricepoint says they carry). I've made all my plans based on 135 spacing, but I may need to reconsider if I can't get the right frame. Anyway - has anyone run an internal geared hub that narrow? I'll be running a rim brake, so no drum needed if that helps. |

Sturmey Archer make the XRF5 in a 113.7mm version (add spacers to taste) and the XRF8 in 116.0mm. http://www.sturmey-archer.com/hubs_5spd_XRF5.php http://www.sturmey-archer.com/hubs_8spd_XRF8.php James Thomson |

I'll be running a rim brake, so no drum needed if that helps. The SRAM 5-speed hub is narrow-- varying from 122mm to 126mm based on what kind of brake it has. I used a Sachs Pentasport coaster brake 5- speed on my GF's (now wife's) bike, which came originally equipped with a 110mm coaster brake hub. The hub has been great-- smooth, quiet, rugged and reliable. The original shifter and clickbox were utter junk, though. My sweetie could hardly ever get the thing to shift into low gear until we replaced the shifter/clickbox with a nicer quality unit. Maybe the latest models come with the upgraded shifter, or maybe not. Either way, it is something to be aware of should problems arise later. The no-brake SRAM P5 hub runs 123mm wide, so it should fit into a 120mm frame without modification of either part. It has the same overall range as the Shimano Nexus 7 hub, but with slightly larger jumps between gears. Chalo |

It's a delightful bike, I really enjoyed riding it with that hub. http://sheldonbrown.org/raleigh-international The Sturmey-Archer 8-speed is a good choice for small-wheel bikes, like my Raleigh Twenty: http://sheldonbrown.org/raleigh-twenty However, I wouldn't recommend it for a bike with full-sized wheels, due to its peculiar gearing. Also, the Nexus 8 shifts quite a lot better. Actually, the Nexus 8 is the best-shifting bicycle gear system I have ever experienced.

My red-band nexus shifts in a decidedly uncertain way, feeling at times as if it overshifted and then dropped back in gearing. I'm careful to ease off during shifts, but still the impression which results is that a strong rider, standing on the pedals, could do some damange without trying. The dealer adjusted it, but didn't really seem to think the problem would go away. The bike has very few miles on it, probably between 500 and 1k. If the shifting improves I'll be very happy. I do agree it's an excellent shifting scheme, mostly because it allows standing downshifts. If somebody could devise a deraillur that shifted at standstill (which I can't imagine!) the Nexus would have real competition. bob prohaska |

Surly hubs (for now), with a carbon straight Redline Fork. I'll upgrade to the 8sp hub later. |
