hookless mtb rims

Mountain rim of the revolution will lead the future of the rim hook
If you ever installed on your mountain bike tire inner tubes or vacuum tire, you may have noticed that part of the rim at the top of the ridge there was, it is the rim wall inwardly projecting a few millimeters, it is called the bead hook, we can call it a hook bead (bead hook). In our minds, this is stuck to the tire bead, the bead hook and when circumstances consistent bead when the tire will remain in place, will not tire from the rim, particularly in support of vacuum tire rim, since you want to allow low pressure bead hook so it will be more prominent, the vacuum will hear when inflated tire bead card fashionable "flap" sound. But now more and more manufacturers began to support carbon fiber wheels straight wall rim design that is completely abolished bead hook, it is possible to obtain performance, more durable and lower manufacturing costs, these advantages make this a long history of progressive left rim features. This seems to be ingrained and we are not the same, and why? Let's look at the technology behind it.
bead hook actually done?
Bicycle rim sidewall bead hook in the rear tire of the tire on the rim to the central push, they are initially aimed at the development of the high-voltage charge when hooked
road tires on wheels.
After the bead hook into the market there are some things happen fifty years, a large number of standardized interfaces between the tire and the rim. Now the central groove rim decline after the tire inflated tire will be positioned in the center of the rim. More wheels on both sides of the groove using a small drop of ridges, called the bead lock, to prevent sliding inside the tire when cornering. The last point, use or batt lips pulled Kay fluorine material means strong and difficult to stretch.
Mountain rim of the revolution will lead the future of the rim hook
ENVE wheels original design is the use of bead hooks (rim sidewall inwardly projecting part), the company recently removed it, said that it can enhance strength and performance.
Advantages mountain rim of no bead hook
Without rim bead hook not only appeared, in fact it is a standard car and motorcycle.
Lightning wheels brand Roval, last year introduced a carbon fiber wheels without hook, hook lightning called zero groove rim, and the recent ENVE Ibis No new rim hook designs also debut. ENVE new M-series wheels for XC, AM and DH design, Ibis introduced their wide carbon fiber rims, which is to develop and Derby, in 2013 they introduced no hook on
the rim design.Mountain rim of the revolution will lead the future of the rim hook
The new wheels ENVE M series covers all ranges from XC to DH, ENVE latest M series carbon fiber rim has been canceled on most mountain bike circle bead hook, you can see the side walls are straight, and we note in the center of the rim to drop slots on both sides of the projection of small ridges (known as the bead lock), which is used to locate the tire. The new structure greatly improves the rim durability and rigidity, allowing better performance wheels.
Lightning Joe Buckley product design team manager, said the transition to non-carbon fiber rim hook design can improve the impact resistance rim, while also reducing
manufacturing costs.
"In the production of carbon fiber rim, there are two ways to manufacture bead hook, you can pass it to mold into shape rim, which is very challenging, because you want a lot of carbon fiber material into a very small space. it has a high defect rate, it will waste a lot of wheels. another approach is to circle formed by the car on both sides of the machine processed bead hook, it can create a good hook, but increases the production process, while but also the processing of more material consumption, carbon fiber material is cut off will produce a weak place. the new wheels no bead hooks, we can get a high impact resistance, but also can reduce production costs. "Buckley says .
Scott Nielson, ENVE development director, explains the transition to a non-hook design brings performance improvements.
"Through our research and development program found that after removing the bead hook and loop we can make performance tires combine better, we feel no hook system performance benefits. Shape of the tire is more stable, so that better cornering performance wheels, and never tire off. "Nielson said.
Our concern is when these companies to hear what users think about from a hook over the rim will cause no hook or off may cause the tire vacuum tire leak. Because the conventional rim, the rim hooks located on both sides of the side walls is mainly maintained tires and to prevent leakage. Clearly these companies have a new way to keep the tire tread and prevent vacuum leakage.
This Derby is a sectional view of the rim, showing its drop center groove of the tire specifically for mountain bikes, on both sides of the groove is in the central projection bead lock, which ensures that the position of the tire, and to prevent leakage.
ENVE in the development of a prototype of the M-series wheels more than a year by laboratory and field tests for various types of tires to find the maximum resistance of the tire to prevent spalling.
Mountain rim of the revolution will lead the future of the rim hook
"A year ago when we introduced our first hook without wheels, we do a lot of the tire from the test, we are very confident that this does not happen, we did not encounter
problems with the tires kept on, whether it be use tube or tubeless mode there is no problem, "Buckley said.
What is the future
So if there are so many benefits while reducing production costs, improve durability and better off-road performance, no hook rim will in the future become the standard for all mountain bike yet? Buckley think it is possible.
"If you asked me a few months ago, I might answer you 'may', but with the release of our new products, which soon became a standard carbon fiber wheels." Buckley said, "but for the alloy wheels, Since the materials and manufacturing methods are very different, they will maintain the status quo. "
Ibis's Scott Nical agrees, "We feel no hook system is the future, enough companies succeed in this regard, others began to change, I believe the bead hook for low tire pressure vacuum is not necessary."
