Vittoria Air-Liner Insert MTB 1.9"-4.0"Punctures are a fact of life, but the Air Liner MTB keeps a mid run flat from imposing an insurmountable time penalty, an auto DNF, or a hike a bike to the transition. The Air Liners high density structure keeps your tire rideable for up to an hour after a flat enough time to clear a stage or hustle back to the trailhead. Your ambitions dont have to deflate just because your tire did. The Air Liner isnt just an emergency flat solution it also helps

Punctures are a fact of life, but the Air-Liner MTB keeps a mid-run flat from imposing an insurmountable time penalty, an auto-DNF, or a hike-a-bike to the transition. The Air-Liner’s high-density structure keeps your tire rideable for up to an hour after a flat – enough time to clear a stage or hustle back to the trailhead. Your ambitions don’t have to deflate just because your tire did.

The Air-Liner isn’t just an emergency flat solution – it also helps prevent punctures by preventing rim strikes. As it compresses, the polymer material ramps-up like a shock. Trail chatter is muted, root lattices are smoothed, and the big hits and square edges of rock gardens are cushioned. The Air-Liner’s cross-section keeps the tire’s contact surface fluid and flexible, but it also increases lateral stability by buttressing the sidewalls.

  • The Vittoria Air-Liner is a tire insert, designed for use in tubeless tires.
  • Air-Liner increases control, durability, performance, and protection of both tire and wheel.
  • Compatible with any wheel size up to 29”, any tubeless valve, and tire widths from 1.9-4.0”.
  • More grip, in both climbing and descent
  • Enhanced rim protection
  • Allows for lower tire pressures
  • Prevents bead burping effect
  • Absorbs high-frequence vibrations. Comfort increased.
  • Allows for tires with lighter casing
  • Ride home with dead flat.

The Air-Liner is a high-quality polymer insert, which replaces a portion of the air volume in the tire. This trait, combined with the shape, provides a tunable system that enhances your ride performances. The Air-Liner destroys the traditional compromise of stability vs. grip, and allows your tires to remain stable, grippy, and controlled, even at low pressures.The Air-Liner is designed using a round cross section, with channels on the top and bottom. The top channel provides room for the tunable air chamber that sits directly beneath the tire tread. Upon impact, the corner edges of the channel flex first, and progressively build to the thicker portion, as the tire is compressed. This allows the tread to remain flexible, which increases traction, without sacrificing impact resistance. The bottom channel allows for easy fine-tuning of the air chamber, and allows for full compatibility of all valve core styles. The round cross-section shape mimics the natural shape of the tire, and supports a greater contact area within the sidewalls of the tire casing. Side-to-side tire stability is increased, yet the tread remains soft and grippy. This improves cornering, climbing, and braking performance

• Protection: Both wheel and tire are protected by the Air-Liner insert. By cushioning impacts from within the tire, your expensive rim remains protected, while eliminating flats caused by rim-strike impacts.

• Control: The Air-Liner insert replaces air volume in the tire. The reduced air volume allows the tire to compress and rebound in a more controlled manner compared to standard tubeless systems.

• Performance: Side-to-side tire stability is increased, yet the tread remains soft and grippy. This improves cornering, climbing, and braking performance.

Durability: This highly durable polymer material has been tested to a projected life of 2000 hours under normal riding, or 1 full hour of run-flat downhill use under a typical rider.

The Air-Liner MTB is available in 3 sizes and is compatible with all makes and models of tires.

  • size S 35mm for tyres 1.9" - 2.25" - weight 90g*
  • size M 45mm for tyres 2.25" - 2.50" - weight 165g*

delightful read
Format: Kindle
What a delightful read. The characters are awesome, the plot was so good, I loved it. I was intrigued and it kept me wanting more. Told in multiple pov, the book sucks you in and doesn’t let go. I cannot wait to read the next book.

not bad
Format: Kindle
I loved the plot of this book. The characters just didn’t have a lot of depth. The connections and “love” just weren’t communicated very well in the writing. The author didn’t write the sweet psycho trope very well at all either. Lachlan was just a mess of a character.

A Beta Worth Rooting For
Format: Kindle
In Spare, Violet Fox flips the omegaverse on its head, giving us a Beta heroine determined to make her mark. Joining the Beta Trials to support her sick father, she's thrown into a pack that doesn't want her, especially the possessive Alphas. But here's the twist: their sweet Omega turns out to be her scent match. Cue the angst, forbidden tension, and a slow-burn romance that will make your heart ache in the best way. Violet Fox delivers an emotional, refreshing take on the genre, proving Betas aren't "spares." They're stars.

Beta, Alpha, Omega oh my!
Format: Kindle
Omegas are precious and given to Alphas & their packs... but the Betas want in too. To this end, the Beta government is rolling out its trial of assigning a Beta to each Alpha-Omega pack. But forcing a Beta into a pack where they are not wanted will not end well... Of course, no one expected the Omega to fall for the assigned Beta. Great read and cliffhanger

A familiar story, just with…..less.
Format: Kindle
So, as other reviewers make clear, this is very similar to Pack Darling and The Beta. It’s much closer aligned with The Beta, in plot and maybe more like Pack Darling with characters. That being said, I don’t hate this…..but it wasn’t great either. It’s both books mentioned but just….less. Less angst, less emotion, less feeling. The plot feels very half fleshed out, and the “bad guy” feels underwhelming. I didn’t really feel any real emotions from and of the male leads, except maybe Oliver. The others fell sorta flat for me. And Mika makes herself out to be this big bad ass straight outta training and then we never see it from here again with the one fitting room incident as the exception. SPOILER: The whole, “Oh, I’m actually probably an Omega, but I don’t wanna be but I do actually wanna be but no one can ever know my secret that I do nothing to hide “ thing fell so flat. She never commutes to believing she was secretly an omega, but also mentions her “secret” a lot. It just felt so manufactured. I’m intrigued enough to read part 2 and see how the author closes everything out, but this is not one I’ll recommend or ever come back to.
