Syncros Crank-o-Matic Crank Bolt Older Cranks

DESCRIPTION

  • It’s more than weight. Cold-rolled threads make these Ti6-4 bolts just as tough as steel. Only at 1/2 the weight.
  • They’re lubricated. Tiodize II and TioLube 40 inpregnates the metal, preventing galling and seizing associated with titanium bottom brackets spindles.
  • A 6mm Allen key. That and a beer is all it takes to install your crank.

    My crank-o-matics are light and trick. They work awsome. You guys whose don't work it is oporator error. Install them right. Read the instructions. Have a bike shop do them. The shop I work at knows how your shop might too. Do them right and they will be awsome.

    Strength:

    One hex key installed and removes crank (no more crank puller).

    Light.

    Won't rust.

    Weakness:

    Won't work if you don't read the instructions!

    If you read the instructions you'll notice that the Crank-O-Matics require a steel bolt for initial installation. Ti prep is needed on BOTH brass washers to prevent seizing and on the bolt threads and edges. A thin application of Ti prep is also a good idea for the spindle.

    I've had no problems aside from the break in period within the first 50 miles. A good product all around.

    I'm not sure what's up with the Syncros' customer service but I've called recently and asked for stickers for my fork (free advertising, no?) and never got a reply ot the stickers. And judging from the reveiws below a few other folks haven't had much luck either.

    Sounds like another case of corporate crappery. Thanks GT/Riteway.

    Hey , never had problems with my bolts. After reading these reviews I won't give
    up five chili's. Synchros should take care of their customers better, in my dealing with this company on other products I know that they are a bunch of
    hard heads...but that will come around to bite them, in the meantime if you
    know your stuff you shouldn't have trouble with the crank-o-matics

    My disappointment with these things is rivaled only by my disappointment with Syncros. The retainer ring on my left crankarm has shattered and I may not be able to salvage the crank arm. When I e-mailed Syncros for advise they told em to take it to a bike store for repair. Its their ring that exploded adn possibly destroyed my crank but do you think they would bother to help out. DO NOT BUY THESE BOLTS!!!!!!

    like too many other people on this page i have found that the crank bolts them sleves are good, that is to say that the titanium fastener bolt does what it is supposed to do. this is not the problem, the problem comes when the removal of the bolt is done to remove the crank arm at the same time. the outer bolt that srews in to the crank arm shatterd on the first removal of the drive side crank. i am also dissatisied at the fact that Syncros's warenty does no cover threaded items, so getting hold of another pair of bots is not an easy task. However this is a shame as the cranks that i also purchased from them are perfectly fine.

    I purchased these bolt to have easier access to my BB and cleanings.
    After installation (on the same day), these things seized up so bad
    the inner bolt cracked through the outer titanium ring. It is a pain
    in the ass to pull suckers out. I found out this is not an isolated
    incident. I'm getting them exchanged(if I can get them out!) but I'm
    very hesitant.

    Simply the easiest to use and coolest crank bolts on the market today. Light, simple and solid, it's one thing I can no longer do without. All you need to extract your crank arms is a 5mm allen key and bingo!! you take your cranks off on the trail in a second. Chain suck can be fixed in a snap, so does noisy cranks. Just take them off and add a bit of grease (if you don't carry grease with you just unscrew one of your fork caps and take a dab of grease on the M.C.U. stack )and you get rid of the anoying noise.

    The large bronze washers get seriously thrashed after a few removals and installations. It would be nice to be able to get some fresh washers to replace the warped old ones. I have E-mailed Syncros to find out if they could just sell me some new ones. They just say, get them at a bike shop. I then E-mail them again and tell them no one around here has them. They give me the exact same answer. I hate to say it because I really have liked Syncros products, but this kind of attitude by Syncros shows me their true colors. In the future, I most likely will seek out the companies that truly appreciate their customers.

    This is my second review, so read below, too! I extracted my drive side crank arm with no problems, just back the bolt out and off came the crank, wellllll, not so with the other arm. The aluminum collar shattered so I had to use a chisel and hammer to back it out on one of the sharp edges. So, if you use these, remove your cranks and clean the spindle and crank mating surfaces regularly or your experience may be like mine.
