Pro Threaded Headset, 1" Steerer

Does the trick for an old JIS standard. Bearings are of good quality, finish is nice. The reviewer who stated a JIS frame cup diameter is 30.2 is confused. A JIS frame cup is indeed 30.0. The difference between JIS and ISO is the fork crown ( JIS=27.0 and ISO=26.4). 30.2 frame cups are found on old Professional Campagnolo, Raleigh, and some older French and Italian bikes. The older French and Italian bikes were the only ones available with the 27.0 fork crown and a 30.2 frame cup. As far as being tall, yup it's very tall for a 1" headset. It's 42.5mm tall. Sizing a 1" headset can bit a real pain to get right. If you don't know how, let a good bike shop do it for you. This is a link to all the headset information you could every want or need. [...]

I wanted to replace the original caged bearing headset on the 1993 Cannondale m400 I am restomodding. I had just used their rear break hanger and quill stem adapter on this bike, both of which I was impressed with in performance and fit and finish. I like working on bikes, it very satisfying and relaxing for me. I tell you, this headset replacement went so smooth and the fit was so perfect, I actually was disappointed that it was over so quickly. For the price, I think this component is an excellent value. Looks good, made well and the tolerances were perfect for my bike. A couple notes: pull the bearing cartridges out and add more grease the races, that way they will not fall out or become misaligned during installation. Also, people have commented on their stack height changing. Mine decreased by ~3mm. Sadly, there is no sticker. Booo!

I had ordered a "Velo Orange" headset previous to this one. The Velo Orange headset was just plain crap. It didn't line up and had tons of play that could not be adjusted out. This one, FANTASTIC. It has cartridge bearings and fit the bike very nicely and was a snap to get the play out whilst steering smoothly. WIth just the headset, the bike rides like new!

There arent many sealed bearing 1" threaded headsets around. I hesitated to purchase a head set at this price, but I am glad that I did. The sealed bearings are smooth and the head cups fit tightly into my steering tube. My last set (Neco) went in a little loosely for my taste and kept needing tightening. So far, this Origin 8 headset needs no re-tightening.Thats nice and why I bought this one. Comes with two size crown races for your fork.Just be sure to follow the directions for assembly and get the correct pieces in the right order. Thanks Origin 8! I reccomend this headset.

This is a conventional headset, not cartidge bearings. they come apart and should be greased accordingly. The stack height was to much for the frame it went into. IT was noticably taller the one it replaced and the lock nut would not screw on. I modified the one I purchased to fit. All in all, a quality item.

This worked great for my bianchi advantage. This headset comes with two crown race sizes. I highly recommend if you want to ditch your old bearing race for a new sealed style headset! 5/5!

Origin8 makes/markets great stuff. Can't go wrong with anything they make.

This thing is gorgeous! It looks very sharp on the vintage Japanese 10-speed I am restoring. Headset arrived without any dings or scratches and installed without any issues. However - it was quite tight, so I removed it, took apart all bearings, packed everything with grease and re-installed. after that it is smooth as butter. I had no issues with any play after install. The bearings, as others have mentioned are not true "sealed" bearings, but the do snap together quite nicely. I am guessing that any issues people are having may be to the bearings not being properly aligned and snapped together. The other thing to be aware of - is the stack height. The lock nut is a good 2 to 3mm from the top of my steer tube, so I will have to use the top race from my previous headset (after painting it black of course). Even with the two negative things I mentioned, I still give this headset 5 stars and will more than likely purchase another in the future.

Instalada en mi bicicleta de carretera, funciona perfecto! Con varios tamaños de corona para distintos diámetros de horquilla!
