When you buy a new set of rims for your bike, you will have to decide whether or not to use Presta valves or Schrader valves. I recently found a lot of people who like the valves but want to continue using their high-end rim with PrestA valves on it. If you can build or not and you are drilling your new wheelsets with both Prestas and Schraders valves, we recommend you choose the Presto.
When you buy a new bike pump, look for one that is compatible with both Presta and Schrader valves. A Schraders pump with Presta valves can also be picked up for a penny in any bike shop, but you have to behave yourself. If you are attached to a Schraders pump, you can use a PrestA / SchrADER adapter And you don’t even need an adapter. For example, when I inflate a Prestas hose at a gas station, I have to fit the Prestas valve into a Schrader bicycle tire valve to inflate it.
If you have a very narrow rim tire, it may not be necessary to use a Presta valve, but if it is built into a larger Schrader rim hole, a reducer or grommet can be used to take up some of the extra space. If the Prestas valve fits into the larger Schraders rim holes, you can use the reducers or the heavy plate to take up the extra space, or if you fit the Presta valves into larger Schraders rim holes, the rims and / or the valve itself can also be used as eyelets or refill valves to occupy additional spaces.
If you have a Presta valve on the tire, you need to get a pump that is compatible with the Presta valves and an adapter valve that fits. If you do not want to work with a normal pump or replace the entire Prestas valve, you will need to buy a tube for your tyres, it is better to take a tyre with you to fill up at a petrol station. You can pump the Prestas hose without an adapter, but you will need to dock a PrestA valve to the tire or get another pump that fits.
If the Presta tube fails and there is no bicycle shop in town, you will not find a replacement. If the Presta tubes burst or you are not in one of the bike shops in the city, you cannot even find a replacement, even if it is available.
In cases where you use Presta hoses on a Schrader rim, you must take precautions. In these situations there must be some kind of instruction on how to fit the Presta tube on the rim.
Presta valves can only be placed on a Schrader rim as a stopgap, and this is not advisable for anything other than emergency repairs. Presta – Special tubing can be fitted to rims drilled into the valve, but this is not the same as with a normal valve.
In the meantime, the only way to place a Schrader tube on a Presta rim is to widen the valve hole, which is not recommended because it could compromise the integrity of the rim. Remember that anyone with a Presta problem can simply use a 21 / 64 inch drill to widen the valve hole and his personal post – the PrestA era can begin. If you have a rim drill for prestas or only have it at hand, you can use it if the hole is wide enough to fit a valve through, but only if it is deep enough.
If you need to fit a Presta tire on a Schrader rim before driving home, you can tighten it to the rim with a small nut. If you need to install a Presta tube on your Schraders rim after returning, use valve nuts to attach it close to the rim if you have it. It should be noted that the installation of a prestige valve on the Schroder drill rim should only be a temporary solution.
It can move a lot, and the rim edge can damage the valve to turn the tire. If you have such a wheel, the Presta valve fits only on top of the rim, not below it. There is a good chance that the pipe will get trapped in the valve opening and blow out, but it can be moved so far that the valve of the pipe actually cuts into the rims. Make sure that both rinses on your Schrader are wider than the Presta pipe to widen the valve hole.
The easiest way to prevent this is to use Wheels Mfg Presta Stem Savers, which glide over the Presta valve and fit tightly into the larger rim hole. Adjust the hole diameter and use a special adapter known as the Schrader PrestA spout to fill the space and secure the new Prest valve. If your bike’s tyre is low and you have a Prestas valve, the air tube is virtually worthless. It costs a penny to mount a Prestas tube on a beak rim, but adapting it to the hole diameter costs hundreds of dollars.
