Frans_MH Posted October 4, 2012 Posted October 4, 2012 Hi all I will be receiving a new frame next week that comes with a semi-integrated headset. I have never had to install one of these so I have no idea what I will have to do. I cant find a good video on YouTube about it so if anyone could guide me through I would greatly appreciate it.Also I don't have access to a press fit tool but I read somewhere it can be done with a piece of wood and a hammer? Thanks!
DR ◣◢ Posted October 4, 2012 Posted October 4, 2012 Wood and hammer is the quickest way to cock up a frame. Pay a professional the R100 odd to do it right. Chances are that if the frames comes with the headset it will be installed already. Only thing to so is install the bearing race on the fork and you are good to go.
TheV Posted October 5, 2012 Posted October 5, 2012 Uhm... semi-integrated headsets are usually used in carbon frames, and you just push them in with your fingers... almost impossible to do it wrong unless your a real "tool". It's the threadless (inset) types that require more careful installation... As for the crown installation, go buy a pvc pipe, and use it to press it over the steerer, you can get enough force using your hands only, dont even need a hammer

As for the crown race installation... just buy a Hope headset! Those crown races have a split in them so one can literally just push it on by hand http://www.jejamescycles.co.uk/product-images-large/hope-07-fork-crown-race-41296.jpg http://www.cyclistno1.co.uk/assets/images/Maintenance-Articles/Hope-Headset-Service/P1030064.JPG Edited October 5, 2012 by patches TheV 1

It's like eating candy floss with a knife and fork.... perfectly possible, but stooopid
Johan Bornman Posted October 5, 2012 Posted October 5, 2012 We don't know what your workshop/garage has in the line of equipment but if you have a big vice, you're all set. A carpenter's vice will work really well. Press the cups in one at a time. Protect the frame from the vice jaws with some wood. You will need help since there will be too many things to hold in place. Make sure the cup enters the frame nice and true. If it goes off centre early on in the press, correct it by pressing on the laggard side only until it is square. Once the one cup is in, do the other one, but don't try and press both at once. The headset race is more of a problem. This will easily damage if you force it in with an inappropriate tool. A well-sized piece of pipe will do but the chances of you having one at hand are nill. I'm all for split races, it is a good idea with no apparent downside. If you don't have a vice, your hammer and wood idea is good too. Howver, be ultra patient. Have an assistant at the ready. Hit once and then inspect for true and protect all bike surfaces with wood. If you can solve your headset race problem, the operation should take you 6 minutes. We're timing you.
Frans_MH Posted October 5, 2012 Author Posted October 5, 2012 Lol, would love to see someone use a press-fit tool to install a semi-integrated headset... It's like eating candy floss with a knife and fork.... perfectly possible, but stooopid I actually did a bit of reading on this, apparently some semi-integrated headsets require a press fit and some don't. It depends on the manufacturer. I guess I will wait until I receive it to see what i'm dealing with. These damn strikes are making delivery feel like a lifetime.
Frans_MH Posted October 5, 2012 Author Posted October 5, 2012 (edited) @missionS: I am in Pretoria East, thanks I might take you up on that deal if at first I don't succeed. @Johan: I will go buy a piece of pipe today, however I'm not going to go for any 6 minute record, if I damage my new frame I will cry for 6 days.

patches Posted October 5, 2012 Posted October 5, 2012 I think some confusion has been made between semi-integrated and integrated. As MissionS has bointed out, many (if not all) "semi-integrated" headsets requite pressing becasue there are still cups that need to go into the frame. On the other hand, "integrated" headsets are what I think The V has in mind, where the cups are moulded into the frame. These types (like on the Cannondales) are where one simply drops the bearings into place.

TheV Posted October 5, 2012 Posted October 5, 2012 Kerzactly. However I dont see where confusion could creep in. OP did say semi. Ha! ... for the first time I have an opportunity to differ in opinion with JB and Patches... whooop hoooo My comment was based on my thinking that most "new" frames, especially the carbon ones are often advertised as "semi-integrated", because they have a head-tube-race built into the head tube.. as opposed to a "fully integrated" one where the bearing sit directly in a "machined" head-tube.... A good example of this "semi-integrated" design is as per my LOOK MTB you help me built a couple months back JB? the bearing just push into the frame onto an integrated race... I've built 2 carbon road bikes during the last 6 weeks where this was exactly the case, the Headset is advertised as "semi-integrated" but really it's FULLY integrated... So, I'm still betting that the OP's bike will not require a press-fit installation other than for a couple of fingers...
patches Posted October 5, 2012 Posted October 5, 2012 haha! listen to MissionS, he knows what he's doing! His garage is kitted! heck, he even machined a custom washer for my Hope rear hub once, wich withstood 2 weeks of DH-ing in the alps
