His take on it was that modern carbon frames are so solid that all the torque gets transferred to the back wheel. He said the issue was that the relatively weak rear spindle (that is hollow due the the quick release) moves about and that causes the squeak. He popped the bearings out on both wheels and really greased them. I took it out on a 100 mile ride yesterday, it was fairly warm and the ride had a couple of 10% rides. Guess what? Not a single squeak or clunk!

It fit my Shimano Hollowtech crank easily. As the French style is of limited demand, Phil Wood seems to about discontinue the line. If it had not been for finding that component, my rebuild of a Mondia 1976 frame would have been sidelined a bit. Was wondering about a press fit into a French threaded hanger but with the creak problem, probably would be careful on this. Good to know about Velo Orange still making French BB.

In this case you need to put some loctite on the outside of the bearings and let it dry out a little. Press the bearing in and take care that the green loctite wont get inside the bearing.<br /><br />So far, Best standard seems PF30, Basically because it has a high diameter and is small so you can fit every crankset you wan't (all with different adapters from different brands, but they are out there). And secondly, You always use some sort of cups, so you don't need to worry for loctite to get into your bearings and can use a whole lot so you are sure it will solve the creaking.<br /><br />However, So far green loctite has been my friend and i have had no creaking with it so far.Anonymoushttps://www.blogger.com/profile/02874117179585354088noreply@blogger.comtag:blogger.com,1999:blog-8492685525705691186.post-36203249704919468522014-12-05T11:13:35.035-05:002014-12-05T11:13:35.035-05:00Do they make adapters to use a threaded BB on a pr...Do they make adapters to use a threaded BB on a press-fit frame? I suppose somebody probably does. But the creaking comes from the interface between the adapters and the frame which may not be made to exactly-matching tolerances -- so if it creaks, a threaded BB adapter may not fix the problem.

Velo-Orange offers some French threaded BBs, and at the high-end, Phil Wood has always made mounting rings for French threading. The external cup BBs are fine -- threaded into a BSC shell, they are secure and should be "creak-free." I have the external cup "Ultra Torque" BB from Campy on a bike, and apart from some solvable engineering issues (namely, using shims instead of the "wave washer" that Campy supplies in order to properly set the bearing pre-load), it seems to work well.Brookshttps://www.blogger.com/profile/12110998345857993287noreply@blogger.comtag:blogger.com,1999:blog-8492685525705691186.post-4087983611290907162014-09-08T10:21:43.900-04:002014-09-08T10:21:43.900-04:00"if you've got a bike with a threaded bot..."if you've got a bike with a threaded bottom bracket, 'hold on to it'"<br /><br />As long as it is English or Italian, you're fine.

The main point I wanted to get across was simply that "new" is not always "better." Given a choice between a new bike with a threaded BB and one of the new press-fit units, I'll take threaded. Easy choice.Brookshttps://www.blogger.com/profile/12110998345857993287noreply@blogger.comtag:blogger.com,1999:blog-8492685525705691186.post-84193375258441455602013-10-23T08:02:15.965-04:002013-10-23T08:02:15.965-04:00Brooks, threaded bottom brackets are still widely ...Brooks, threaded bottom brackets are still widely available, from cheap Shimano UN series to their better ones, to SKF (as well as Phil Wood, whom you mentioned) at the high end. Given the millions or billions of threaded frames out in the world (and still many being sold new, from low end department stores to mid range Surlys and Soma to high end customs, plus the innumerable bikes sold outside of the US) I don't think they'll disappear anytime soon. <br /><br />I'm enjoying the blog -- nicely done!
