Are Alexrims good?
Are Alexrims good?
They held up beautifully. Seem to be good, sturdy, quality rims overall. This is my only experience with Alex rims but seems like they’re a great product for the money. Also, how well they’re built up initially will have a lot to do with performance.

Alex rims website does list their rims as tubeless ready, just add tape.
Where are Alex rims made?
Taiwan

How do I know if my wheels are tubeless ready?
A tubeless ready rim will have a sidewall with a hooked design, which helps catch and hold the bead. Older rims will appear rounded without a hook shape. The shape of the rim will force the bead up snug against the outer hook, and will have a deep section in the middle to make it easier to remove.
What does Tubeless Ready mean?
What does Tubeless Ready mean? Tubeless Ready tires can be used both with and without an inner tube because the tire and wheel rim are designed so that they directly seal each other. In contrast to UST tires, Tubeless Ready tires are much lighter and are therefore air-permeable in the sidewall.
What are the disadvantages of tubeless Tyres?
Tubeless cons
- More expensive.
- Fitting is messier and more time consuming.
- Removal often requires good grip strength.
- Air and sealant can escape (‘burping’) if the tyre bead comes away from the rim due to a sudden impact or extreme cornering force.
- Sealants that coagulate need topping up every six months.
Can you convert any rim to tubeless?
While many new mountain bike wheels ship as “tubeless ready”, you can actually convert your existing wheels to a tubeless system. There’s no reason to get rid of it and many tubeless kits recommend using two layers of their tape if you do remove it. Old tires, tubes, and rim tape. Good riddance!
What are the benefits of going tubeless?
What are the benefits of going tubeless?
- Pinch punctures are virtually eliminated.
- It’s possible to run lower tyre pressures for improved grip.
- Even multiple thorns are unlikely to cause issues.
- It’s generally much lighter.
Which is better tubeless or with tube?
Since air is contained within the tubeless tyre itself, and not in a separate tube, high-speed stability will be better. Also, since a tubed tyre has more components (tyre, tube, rim) compared to a tubeless tyre (just tyre and rim), performance and efficiency are better with a tubeless tyre.
How long does tubeless sealant last?
2-6 months
How much does it cost to go tubeless?
LBS here is $40 labor per wheel to “install tubeless system.” Tape, sealant and valves will put you over $100. In a lot of cases that would be around $300 per hour, not bad (for the shop) $100 including tape, sealant and valves sounds about right, shop prices for the parts are probably about $60 or so.
Is tubeless worth going?
There will always be people who ardently defend tubes and say that tubeless is a gimmick or not worth it. But in most every instance of mountain and trail riding, tubeless is – by far – the lightest, most reliable and cost effective setup you can ride. Like any system, tubeless needs maintenance.
Are tubeless tires faster?
The tires rolled at almost the same speed. Even with almost no liquid sealant inside, the tubeless setup rolled only marginally faster. For both comfort and performance, it’s better to run a supple tire with sealant than an air-tight, but stiff, tire that can be run tubeless without sealant.
Can I put a tube in a tubeless tire?
Putting a tube in tubeless tires The procedure for tubing tubeless tires is the same as for regular tires. With the tubeless valve removed, you can place a tube in the rim in much the same way as a regular tire. You will most likely have more difficulty getting the tire bead back over the rim.
Can you run tubeless tires without sealant?
A true tubeless tire can hold air without sealant, but a tubeless-ready tire requires the sealant to become airtight. A tire with a regular bead will blow off the rim when inflated to higher pressures without a tube. So you MUST use a tubeless-specific tire if you want to ensure your safety while riding.
What happens if you get a puncture with tubeless Tyres?
What happens if I puncture? A huge advantage of road bike tubeless tyres is the reduced risk of puncture. The pressure may drop slightly in the tyre as some air is lost and thus also allow the sealant to seal the hole and it is still possible to ride home on tyres with around 60 psi in them.
Do tubeless tires have less rolling resistance?
Road tubeless tyres’ rolling resistance is lower than that of both clinchers and tubulars due to the friction between inner tube and casing being eliminated.
Are clinchers faster than tubulars?
That’s right, clincher tyres, used correctly, can roll faster than tubulars. ‘Power losses in the bonded area between the tubular tyre and rim are fairly high,’ says Bontrager. ‘So a carbon wheel with a very light clincher tyre and efficient inflation has the potential to roll faster than a tubular. ‘
What’s better tubeless or clincher?
The major advantages to the tubeless setup are 1) that you rarely get flats and 2) that you can run lower pressures (without pinch flatting) for better traction and ride quality than clinchers. If you do get a flat, you can simply add more sealant and/or use a tire plug to fix it.
Does rolling resistance really matter?
Most laboratory-based tests of rolling resistance find lower resistance at higher pressures, but this doesn’t always transfer to riding on actual roads. Therefore, in real-world usage, wider tires probably don’t have lower rolling resistance than narrower tires, but they do give more comfort, which is important.
What is the benefit of low rolling resistance tires?
Low rolling resistance tires are designed to reduce the energy loss as a tire rolls, decreasing the required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency as approximately 5–15% of the fuel consumed by a typical gas car may be used to overcome rolling resistance.
Do wider tires slow you down?
Wider tires = more weight + more rolling resistance = slow you down. But, if you’re getting wider tires because of traction issues, I think that having better traction will be more beneficial.
Do larger wheels have less rolling resistance?
Larger wheels have less rolling resistance, for several reasons. Second, They have greater leverage for lifting the wheel over bumps. Third, there is less deformation of the tire at the contact patch on the ground. Fourth, smaller wheels require faster chain speeds, which will have higher frictional losses.
Do smaller wheels go faster?
The diameter of a larger wheel means that its circumference is larger. So, a larger wheel will actually turn slower, but move a vehicle forward faster than a smaller wheel. The smaller wheel will take less torque to get moving, but the larger wheel will give a faster overall speed.
Are 25mm Tyres faster than 28mm?
‘Also a 28mm tubeless tyre is the fastest setup [in rolling resistance tests]. Comparing rolling resistance, a 25mm tubeless tyre at 95-100psi is the same as a 30mm tubeless tyre at 72-80psi. ‘
Are smaller wheels faster?
Yes, smaller wheels accelerate faster, but it doesn’t matter. A 29” wheel has more mass at a larger radius from the centre of rotation (the hub), and thus has a higher moment of inertia than a smaller wheel and is harder to get moving. So yes, bigger wheels will accelerate more slowly.
Are Bigger wheels safer?
While larger-diameter wheels and tires should improve handling and high-speed performance, lower-profile tires also tend to have a firmer ride and may be noisier than the smaller, standard rubber. Some potential performance benefits may be offset by the additional weight of the larger tires and wheels.
Does wheel size affect speedometer?
Up-sizing, or installing a taller tire, will lead to a speedometer reading that is slower than your actual speed. This is because a taller tire will have a larger overall circumference, which will cause it to travel more distance per revolution than the original equipment tire.
Does wheel size affect fuel economy?
For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.
