Drilling a stem?
jim beam wrote:
regarding the cable run, there should not be much of a friction problem. are you sure the cable's cut square so it's not pinching at the end? and the noodle still has its liner? Yes on both counts. The cable slides very smoothly in the housing but not so through the 45-degree noodled hanger (which does have the liner in place). Another reason why I'd also like to switch away from the noodled hanger is that currently I have no means of cable adjustment. I have a Dia-compe hanger which has an adjuster, but I can't use it without drilling the stem. V brakes would be another possibility because I have a pair of Dia-compe V brake noodles with adjustment barrels lying around, but then there's the cable pull mismatch to be solved. But I guess I'll first try either the long-drop IRD hanger or a hanger mounted on the fork crown. I'm sure all this was figured out long ago by most cyclists, but my first bike ever had V brakes and I never had cantilevers before getting a cross bike for winter riding. -as |

Because it's cyclocross and therefore has road bars and therefore V-brake levers are damn near impossible to find, I'd guess. If the bike has Ergo or STI levers right now, you can't go to V-brakes at all unless you replace them with bar ends. Jasper |

you could try a cheaper [thicker walled] stem and drill that - lots of early mtb stems were drilled in this way and i don't recall seeing any failure issues. the wcs is too light to do this though imo - and if you're riding a crosscheck, i doubt weight is your primary concern so a heavier stem should be no problem. Early MTB stems that were drilled were usually aluminum quill stems, where the extension is solid aluminum. Or they were tubular steel, and there was a little tube welded in with a stop for the cable. (Having that tube in there makes the hole a less likely place for cracks to initiate.) Either way, the substrate was more beefy than a current hollow aluminum threadless stem. I agree that drilling a WCS would be bad, and would shy away from drilling any modern hollow stem, actually. The really trick way of solving this problem is to have a stem built with a cable stop and pulley under the extension. Unfortunately these were rare in quill and even rarer in threadless - I think Salsa made some, they should bring them back. Looping the housing over the stem and down to the hanger improves routing but may not be enough for the housing to clear a modern fat stem, since a threadless stem is so close to the hanger. A deep drop headset hanger, or a fork crown mounted hanger, is probably the best solution. For a cable adjuster, try inline cable adjusters. Also, if you (the OP) install Runkel levers (top-mount inline levers), get a model with cable adjusters. These can really help. Cantilever brakes without a cable adjuster in the system are a royal pain in the ass to set up. In fact, installing an inline adjuster might help you set up the brakes so that they work adequately with the existing 45 degree noodle thingy. |

Pro: brakes work the way they're supposed to. Con: expensive. Or use your v-brakes with your current levers, without an adaptor. Pro: cheap. Con: depends on your setup and who you ask; canti levers + v-brakes have worked for me on two bikes, but it's a finicky combination (very little pad/rim clearance, very little feel at the lever). Or use mini v-brakes with your current levers. Pro: works properly. Con: expensive, setup is sort of finicky. Or put your semi-horizonal drops to use and make that Surly a brakeless fixed gear. Pro: lose 4+ pounds. Con: yikes. Or get creative with the cable routing to make your current parts work. IMO, the best option. Maybe take the bike to shop, see if they have any ideas. Feel, power, cost, etc. of your current setup makes it better than the stuff I listed above. -Vee |

On this page: http://www.gaerlan.com/bikeparts/par...es/brakes.html you will see: - QBP Travel Agent w/ adjustment barrel, fixes the cable pull mismatch as well as the adjustment need. - Jagwire in-line cable adjusters - an example of a steerer-tube cable hanger with a drop, that costs a lot less than the IRD model. This one is just for 1" steerers, not your X-Check's 1 1/8" model, but it serves as an example of a part that you can find at nearly any shop for a very cheap price. I have used the Travel Agent with some Avid V-brakes on my CX bike for a few years. It works great! I've never had any problem with it, but I do recommend using a high quality, brand name (Avid, Jagwire, etc.) brake cable to avoid (or delay, perhaps) cable fraying in the sharp curve of the Travel Agent. I use a coated Avid cable and after 3 years have not had any such problem--but I was warned about it when thinking about the Travel Agent + V-brake solution for my bike, so I am passing it on. All of these items should be easy to find at any good bike store! Best of luck. -- Gregory S. Sutter "How do I read this file?" "You uudecode it." http://zer0.org/~gsutter/ "I I I decode it?" |

The Tektro 927 Mini v-brake at $15.99 plus shipping is hardly "expensive." Available he http://www.amazon.com/exec/obidos/tg...16609?v=glance How is setup finicky? They're v-brakes! This fixes all cable routing issues, is cheap, looks trick, and also has much easier pad adjustment compared to cantis. It's the obvious choice. -- Phil, Squid-in-Training |
