AVID Shorty 4 brake on Mountain Bike with road levers?
Another option that I'm thinking of is setting up the bike with disc
brakes. I've seen cross bikes setup with disc brakes. But, I'm not sure if the "road" levers are standard road brake levers working with the disc brakes. Maybe they are special disc brake road levers??? Also, to be more clear on my 2nd question regarding the rear derailleur - is it possible to run a 105 cassette on say an LX rear hub with a 105 rear derailleur? Or, can I control a LX rear derailleur and cassette with a 105 shift lever? Yet another possibility would be to setup the bike with 700c disc wheels on the mountain frame - but I'm not sure if 700c wheels with cross tires will fit in a mountain bike frame. Thanks again. -- Marty |

AVID Shorty 4 brake on Mountain Bike with road levers?
Thanks very much Booker for the feedback to my questions. It's very
helpful. I get these ideas for bikes and then I start to think about the details and there are many questions that pop up. I've learned to ask questions about details after my last project - converting an old Raleigh Crested Butte into a SS. That turned out great, but I ran into all sorts of problems and it ended up costing a lot more than I had thought it would and it took a lot longer to complete bcause of all the special order parts and part returns. I plan to plen better on this one. We'll see how it goes... -- Marty |

In addition to the cantilever brakes you could also try the Tektro
Mini-Vs. These work with road levers and save you the bother of adding cable hangers. The downside is limited clearance for large tires or fenders. From the sound of what you are trying to achieve you can still go with 1.75" tires or narrower. The Tektro Oryx cantilivers are also available rebadged for Cane Creek and Nashbar (black only). There is not much point in spending the money on disc brakes and/or 700c wheels. The only option that works with normal road levers are the Avid mechanicals. These come in a road specific version. You can also get the Dia-Compe 287-V road levers which have modern MTB V-brake cable pull and will work with any MTB mechanical disc brakes. You can use any combination of Shimano 8-9 speed hubs, cassettes, and rear derailleurs you want. You can also mix in any 10-speed parts except for the Dura-Ace hub with the aluminum freewheel body. I believe 8-speed Dura-Ace RDs have an oddball cable cable pull left over from 7-speed and will not work with any other parts. Note that the slant angle of the MTB RDs is greater that that on the road RDs. This is needed to acommodate the wider gear range of the typical MTB casette. The cable pull is still the same for road and MTB, through, which preserves the interchangeability. If you use the "wrong" casette with a particular RD then you will experience delayed shifting for a portion of the gear range. This delay stems from the mismatch in the RD slant angle to the cassette. The mismatch prevents the RD from closely following the cogs through the entire range of the RD. My rain/winter MTB is set up with a 11-23 9-speed road cassette and an Alivio RD. I have the B-limit adjust set so the jockey pulley is as close as possible to the 11-tooth gear. The pulley is noticeably further away when shifted over to the 23-tooth gear. This means that the shifting is less crisp and delayed at the 23-17ish range of the cassette. If you use an MTB cassette with a road RD you will experience the same issues in reverse. While not a perfect situation, the delayed shifting is not terribly noticeable and the mismatched parts work pretty well overall. You wouldn't want to race on a bike set up this way but it's OK for general purpose use. You will be best off using the 105 derailleur on the bike but I would use the LX if you already own it. |
