You can install a carbon fork on an old road bike if the head tube, the headset, and the fork are of the same type and size. The first-ever mountain bike World Championships were held in Durango, Colorado, in , but what happened off the racecourse that weekend was probably more important to mountain biking. Threadless stems offer a simple way to swap, flip, mix, and match stems, which are readily available in various configurations and variations of construction, color, reach, and angle.
Threadless stems allow for the lighter carbon fiber or aluminum alloy steerer tubes, and hence a lighter overall bicycle. Threaded headset sizes are designated by the outer diameter of the steering column.
This can seem confusing, because the head cups do not measure the named standard. A threaded headset works with a threaded fork fitting the frame into which it will be installed. A threaded top race screws onto the fork threads, then tightens onto the bearings which are either caged in a retainer or run free in the race.
A washer sits on top with a locknut to prevent the top race loosening. When choosing a headset, look at three things at the earcups, the shape, the material and the open or closed design. If you have small ears and a compact gaming headset, round, on-ear ear cups are an excellent choice. For gamers with a larger head and prominent ears, the larger, over-ear oval ears are a big plus.
Most modern bikes use two sealed bearings positioned at the top and bottom of the head tube. Although internally threaded is a much better option than externally threaded jewelry, you should still pay attention to both the polish and the material to make sure it meets implant grade safety standards. We recommend using an APP approved vender. It keeps your jewelry secure and in place. With externally threaded jewelry, those coarse threads on the end of the barbell have to pass through your piercing when inserted and removed, which is not only extremely uncomfortable, but can also tear and damage the tissue around it.
This damage can result in irritation even for healed piercings. If you have Tip: if you have 26in wheels you can use 26in size forks obviously but you can also get away with running a A semi-integrated or internal, Zero Stack or ZS headset works in a very similar way to a threadless headset but the cups that hold the bearings are pressed inside the frame with just a lip extending out of the top and the bottom of the head tube.
The length of the fork is usually measured parallel to the steerer tube from the bottom of the lower bearing race to the center of the front wheel axle. Quill stems are used in conjunction with threaded steer tubes.
It is wise to measure your components to ensure that you are installing or ordering the correct stem. Another idea featured a separate threaded insert that was secured inside the steerer with a dowel pin. This became the preload [device], which eliminated any need for threads whatsoever.
Coming up with a revolutionary product is one thing; turning it into a commercial is another entirely. Whereas threaded forks had to be made in multiple lengths and then still often had to be cut to fit , Dia-Compe USA could offer RockShox forks that were already pre-cut to exactly the required dimension and with the star nuts already installed.
According to Gilbert, sales in the first couple of years were modest in terms of absolute quantities. Suspension forks were very expensive upgrades in those early years, and even as easy-to-sell, preconfigured bundles, annual OEM orders were in the hundreds, primarily spearheaded by mountain-bike brands like Norco, Rocky Mountain, and Raleigh. Bigger brands were quick to follow — including GT, Trek, and Specialized — as did the road market once the more tech-savvy players realized how much weight could be saved.
Gilbert is still at Cane Creek today. His office looks out at the same hillside in Fletcher, North Carolina, as it did years ago, and he still remembers the watershed moment when he realized that threadless was here to stay.
The game is over. We won. Disclosure: CyclingTips would like to thank Cane Creek for covering flight and accommodation costs as we researched this story, and John Rader for lending us the time to recount his story. Origins: How the AheadSet threadless headset changed bikes forever.
Threaded headsets were the industry standard in the late s. They worked, but were often problematic. With few exceptions, threaded headsets comprise two nuts: one to set the bearing preload adjustment, and another to lock it in place. The idea of clamping the stem directly to the outside of the steerer tube may seem obvious now, but that was hardly the case back then.

Thirty seconds and a broken office chair Rader had already made a number of friends within the mountain-bike community, and when he began to map out his strategy for pitching his threadless headset idea to the industry in , California-based frame builder Ross Shafer — the founder and former owner of Salsa Cycles — suggested that he go to the inaugural UCI World Championships in Durango, Colorado, to speak with Dia-Compe USA.
OEM customers could buy forks with the confidence that they were being manufactured by a company with a solid track record for reliability and consistency, and Dia-Compe USA was able to take advantage of the early excitement about mountain-bike suspension.

This is very easy to look up via a Google search, but for pointers: This sites's Terminology Index and this Sheldon Brown page. I was meaning to ask this today! Great minds.. At least the why of it. Mainly disease of maintenance. Makes the old and new incompatible, encouraging folks to buy new stuff.
Money is always a motivating factor - need to make and stock fewer different sizes has a huge effect on inventory costs. Show 5 more comments. Active Oldest Votes. There's a page on here explaining the basics, Terminology index - a list of bike part names and cycling concepts There are some advantages for maintenance, it is simpler and faster to adjust the bearing preload with the central bolt through the top cap, rather than using the lockrings on a threaded headset.
Hope that helps, no doubt there's more reasons than this! Improve this answer. Swifty Swifty I personally have never seen one.
I doubt they exist in great numbers as the advantage of removable plates became apparent in the period threaded steerers disappearead. In which case I see it as relevant, however the paragraph is trying to make two points and maybe not making either very well so will rework.
Thanks — Swifty. My previous comment was referencing "are there any threadless stem designs without removable handlebar clamp plates? See origin8. Show 1 more comment. As to the what, others have pointed to other resources. Karthik T Karthik T 2 2 gold badges 6 6 silver badges 17 17 bronze badges. It should also be threadless headset or steerer , the stems ,specifically, of both styles are extensively using "threads" — Karthik T. Cheaper bikes have threaded stems because they are awful and buyers can be charged higher price for better solution even if it is cheaper to produce.
Also, BSO buyers like to raise the handlebars and that is the one thing quill stem is good at.
