BBB Aheadstem Steerer Tube Extender

Product Information

So if you have a lot of extra length, are certain of your setup and unlikely to need to raise the handlebars, and you’re wondering: “Should I cut down my steerer tube?” – the answer is most likely yes.

It slots into your steerer tube and extends past the cut point to give you more length to fit your stem onto. it makes the stem higher than on most uncut steerers. And the interface between extender and this extension doesn't seem as strong as between stem and steerer. And the added leverage may bend the original steerer. If you have cut your fork steerer too short, got a new frame or bought a second hand fork we can fit a new steerer tube rather than buy a new CSU or fork. What does an expander plug do? This humble but vital part found at the front of the bike, connecting the fork and the stem and handlebars, can cause some head-scratching.

The answer is no, it's not significantly different in terms of safety whether your stem got where it is using an extender versus an uncut steerer.

Lowering a bike’s handlebars gives you low and aggressive bike geometry, with stiff and responsive steering. So it’s a straightforward way to cycle faster. You’ll cycle faster with a lower handlebar stem and a cut steerer tube, but leisure cyclists might not want to bother with a serious bike modification like cutting the steerer tube. therudd: I think it would lead to a bunch of new standards if they went down the same route as BMX forks. It'd give manufacturers another thing to change every couple of years/months/minutes and if it rounds out, you'll be going to a shop and hoping that they have the right one, as opposed to the star nut which is universal. Granted, it's not something youd be replacing all the time unless you have hands like feet. Had a similar conversation with a gentleman who had a 60cm Madone with a steerer extension. Our conversation ended with him putting down a deposit with me for a custom Moots.Add enough spacers to the steerer tube to set your stem to your preferred handlebar height. Then, add an additional 15 mm or so of spacers below. From all comments, I conclud that what you carry, is to give you also peece of mind. Like protections. No one uses protection to fall! Often when riders cut down their steerer tubes, it’s to increase performance by providing a more aerodynamic riding position. Stem risers do work but have limitations. They increase the amount of force you can put on the headset (as does anything else that gets the handlebars further up), they can break (unlikely but possible), they add a little slop and they often creak (a consequence of the slop). Are all steerer tubes the same size?

You’re likely to find yourself in this position if you’ve bought a second-hand bike and the previous owner has cut the steerer tube shorter than your desired length.

Research shows strong, uncompromised front forks are essential for bike stability, especially at speed. If your steerer tube is already the right length, it was likely built to size by the manufacturer, (or perhaps already cut down by a previous owner if bought secondhand). The expander plug reinforces the area the stem clamps to and prevents damage to the layers of the carbon fiber (Fiber layers can also loosen over time especially with repeated tightening and loosening of the stem clamp). How much does it cost to cut steerer tube?

TDMAN: 1 - In the 3 months I've had my OneUp EDC tool, I've used it 3 times for myself (including once for plugging a hole in my tire so I didn't have to walk home) and a few times to help friends and once to help a stranger. Thankfully with spacers, you’ll have room for adjustment after you’ve cut the steerer tube, so there’s some room for fine-tuning as you go – provided you don’t cut too short. Assuming the handlebars feel right, you’re ready to mark and cut off the extra length of the steerer tube. If you’re certain you want them lower, remove spacers and go again. A stem riser is a hollow tube designed to fit over your fork's steer tube where it goes above your bike's head tube by means of pinch bolts similar to what you would see on standard threadless stems, effectively extending the length of your steer tube and putting the rider in a much more upright position. What is the steerer tube on a bike? On short rides, bellow 2 to 2.5hours, i just carry water, or no water if there are plenty of fountains/water points, and I can drink between them (depends on weather)Bike steerer tubes are most commonly made from aluminum, but are often carbon fiber for high-end bikes. As mentioned, the steerer tube is one part of the front fork as a whole, and the most straightforward way to get a longer steerer tube to work with is with an entirely new fork. It's not the least expensive, because you left out everything else needed to install the OneUp version. What you say in essence is true....it could or can be done. I'd thought about what you could bond it with..metalset, epoxy resin etc etc. The trouble is, it would probably be ok...but what good's probably.
