As the lucky owner of two Schlumpf hubs I must say they are a very significant addition to my riding. The geared 26 is a monster that can handle all kinds of terrain. When in high gear it has the speed of a 36er and in low gear it can deal with technical muni conditions. I really miss it now (it had the bearing thing again) and I'm waiting for the replacement hub every day... But I have learned by now that I have to be patient with Schlumpf and that it can take quite a long time until I finally get the hub back...
So at the moment I ride the geared 36 mostly. It's a blast too. I built that wheel myself with the instructions from John Foss in Uni magazine (not sure which edition) and with Roger Davis' spoke length calculator. When the other hub comes home I will build the 26" wheel myself too. I'm really looking forward to that, because that means I can finally ride the longer mtb trails that are further away from my house again. For really steep and technical things I still prefer my ungeared KH24. It is definitely more maneuverable than the geared 26.

Was your wheel built with a tension meter, or just by truing? FWIW, my wheel that I built with Chuck (without a tension meter) lasted quite a while before I started popping spokes. Eventually the hub failed, and I rebuilt it with a new set of spokes. But, I don't really know the answer to your question. corbin |

When I bought my 36'er I had 3 spokes fail not long after I bought it. Shortly after I replaced them another 3 broke so I had the whole wheel rebuilt by someone who knew what they were doing. It was 12 months before the next spoke broke and then 6 months before a second spoke broke. Good quality spokes help too. (What am I doing in a Schlumpf thread?) |

wheel building

That said, replacing all the spokes and rebuilding the wheel is really more of a comfort thing- as mentioned, use good quality spokes of a large enough gauge, if you're breaking too many you may want to bump up the gauge a step to make them stronger (and heavier). Personally, I go for beefy spokes on my unis, because I'm more concerned about what happens when I take my 36" down a flight of stairs than the extra grams of spoke weight. (I also happen to use extra thick thorn resistant tubes and kevlar thorn protectors on all my unis for peace of mind- they work against glass in the urban jungle too, and I've pulled glass pieces out of tires without flatting before. It weighs more, but it makes me feel better, and I've never gotten a flat while riding that way, not even a snake bite/pinch flat.) If your spokes are too thin gauge, it won't matter how well built your wheels are. Good luck! Jeremy Last edited by Jeremy1981; 2010-01-19 at 05:11 AM. Reason: clarification |

To respond to the three replies above...
My wheel was originally built by a wheelbuilder back in DC, but I don't believe he had a tension gauge...he did it by feel. It was great for 700 miles. After I broke a spoke, I brought it back to fix it, a quick fix was done and not much more effort was put into it...I immediately broke another spoke on my next ride. I then brought it to a friend who is a great wheel builder and he used a tension gauge to true up the wheel and replace the spoke...and the wheel seemed really nice. After <150 miles I broke another spoke, and had someone fix it up and then I had a flat. So it is very possible that it was overtightened and I had a pinch flat. I just ordered a few more replacement spokes from UDC with my last order (gonna try out 165mm cranks and the KH T-bar) - so I am now going to bring it to another bike shop to fix up the wheel. If I get ONE more broken spoke...I guess I should give up hope and order a whole new set of spokes and get someone to completely rebuild it. I have never had any issues with broken spokes on my ungeared 36er, but I am sure that the extra force from the high gear and the fact that I use a brake with my g36 doesn't help. It is getting to the point of being very annoying and I hate it when my ride is not reliable. Would 4 cross help my situation out? I know most people just use 3 cross, but maybe my wheel would be more reliable with 4?

Why is that? I would trust your judgment more than mine since I have zero wheel building experience, but the Schlumpf has pretty large flanges, and from some brief research online it seems that 4 cross is better suited for large flange hubs.

The wheel feels great now, even tension and true. I can't wait to get back on my g36 and try out my new saddle and KH T-bar and 165mm cranks.

Once it gets a little warmer I will tackle some mountains out here and see how the set up works. I think 165s will handle long mountain climbs in colorado better than 150s. The T-bar is pretty cool as well, it feels nice having the handle in a comfy position a little bit further out than a T7, but I do miss the control and acceleration I got with the shorter handles on my GB4. I love my kh/schlumpf!

Last week I ordered a KH26x3, 137/165 dual moments and a Schlumpf hub. I can't wait to ride it but since I often ride on muddy trails I wanted to know if the dirt can be much of an issue. Do you clean the hub and cranks everytime it gets dirty?
And another concern is about shifting by accident. Does this happen often or never? I am thinking of riding technical XC/downhill trails where bumps may cause your foot to move on the pedal and then you shift... and... UPD ![]()

currently not damaged

So far, I never shifted by accident, but: I do not ride on really rough terrain with my KH29. I would say that it can happen if you are really unlucky, but it should not be a big issue. My guess is that it will happen much less frequent than UPDs for other reasons.

I have never accidentally shifted and you shouldn't have any accidental shifts with those long 165s.
