tips for cannondale evo pf30bb, headset, and internal cable
Posted: Sat Mar 17, 2012 2:07 am
warning: long and strange things below....i majored in creative writing and these things just happen.
I learned a few things putting together my 2012 cannondale evo last night:
1. if you are installing a SRAM Red bb30/pf30 crankset, take out the bearing covers (not the actual bearing seal, but the hard plastic cover over the face of the bearing, just inside the lip of the pf30 cup) that come stock on the pf300bb that is installed into the frameset by Cannondale. Cannondale has thoughtfully included a wave washer, and plastic shim washers, as well as two new bearing seals that actually work with the crankset, all in a ziplock bag. I am not sure if the stock bearing covers are meant to work with the SISL crank, but they DO NOT work with a SRAM Red bb30 crank. Even if you try to install the crank three times, torquing it down, backing it off, re-torquing, you will only find satisfaction upon installation of the wave washer, 1 or two shim washers (all of these on the drive side), and a bearing cover on each side (with the text printed on them facing out.
2. the flat headset bearing cover (with "supersix" printed on it twice in white) IS NECESSARY, even if you are using the taller carbon headset cover. the flat headset bearing cover goes on directly over the top headset bearing/split collar thingy, then the taller headset cover can go over the top of it, then your spacers, then a couple of headtube extenders, a few stems so you can add extra sets of handlebars off to the side, then the top cap. Or maybe just the spacers, stem, and top cap. Once again, taking the thing apart, checking everything is seated well, and all looks good, even if done 3-4 times, will not yield a satisfactory result unless the flat bearing cover is in place.
3. if you have removed the white string that came with the frameset, (running from the internal brake cable entrance at the headtube to the exit at the seatube junction) seemingly used to hold the rear internal brake frame guide in place, thinking, "why would they not just put a bit of tape over that little guy? i'll just take that string out!" and then realized later it might have been a helpful tool to run the rear brake cable thru the frame, do not give up hope! I am not sure how much use the string would have been, but 1.5 hours later, i was able to get a brake cable strung through the frame. the key for me was to run first a shift cable (the brake cable was too stiff somehow to find its way successfully back to the exit, wanting to detour down the seattube to the BB (and by the way, NO, the seat tube does not give you any access to the top tube, which might be helpful to find the cable if it did not make it all the way), starting it in the front, and jamming it around until it showed up at the exit (needing tiny long needlenose pliers to get the tip threaded out of the hole). Then i tied a bit of dental floss to that (long enough for 2-3 top tube lengths so it wouldn't get lost, and pulled that back thru to the front. At this point, i tied the dental floss to the brake cable, after making sure the housing was routed correctly, and all other details were right, then threaded the rear brake cable onto the floss, wrapping the floss many times around the inch or so of the tip of the cable, and ending at the very tip, so they would be sure to run in direct line, rather than the tip of the cable being angled at all off the trajectory of the floss. By so doing, in only 90 minutes of learning and cursing along the way (the solution contained herein is only the final successful one, and the other attempts using vacuum cleaners, etc, were not detailed here for space concerns), the cable was successfully installed.
hallelujah!
now if i hadn't all of a sudden gotten a saddle sore last night, due to some wierd inflammatory response to allergies (and not even so much bike riding at all), i would be able to mount my trusty steed and vanquish the demons of an imperiled build process.
i wrote this lengthy treatise in hopes that someone else building up an evo, will be able to scour the internets and find these hopeful bits of hard-earned knowledge, and in doing so, avoid some of the mental anguish i experienced last night, and no doubt contributed to this insane bit of ramble.
thank you for your kind attention\
