Fast, Grippy, & Reliable

The Serfas STM Lesto High-Performance tire with FPS puncture protection is constructed for cyclists looking for a fast-rolling tire that grips corners and thwarts sharp road debris. The smooth center on the tread pattern allows the tire to roll freely on the tarmac, but the added crosshatch tread on the sides of the tire grab onto off-camber corners and tight turns.

Constructed utilizing Serfas Volcanic Speed Silica Compound, the STM Lesto bicycle tire can achieve impressive high speeds, while still retaining cornering grip.

Underneath the high-quality rubber are two layers of FPS (Flat Protection System) casing, which repels sharp objects from puncturing the tube.

Weighing only 205 grams per tire, the Serfas STM Lesto lowers the rolling weight of the wheel, allowing the rider to maximize the efficiency of their power output.


  • Super fast 'Volcanic Speed Silica Compound'
  • Slick center tread with micro file textured shoulder for high-speed performance and grip on corners
  • Single layer FPS Pro and single layer Road FPS for high-performance protection
  • Bead: Folding
  • Supple 120 TPI casing
  • Size: 700 x 23
  • Max Pressure (depending on rims): 130 PSI
  • Weight: (23) 205g

Appears to be a decent tire - Good value

These tires feel pretty "firm" while riding; not bad, but I can feel a difference from others. They also look narrow for a 23mm tire.

I haven't put to many miles on them yet (currently mounted on one of back-up bikes). I didn't have any issues mounting them, yes a little tighter fit then some others - but I took my time and got them on without any problem.

Price range is a good value if you need to watch your budget.

Time will tell for durability.

Lastly would like to see these in 25/28mm size.

Hard to mount, rough ride

I am a long term Vredestein user, but they are hard to find in the prices very high now. I bought a bunch of these in the 23 size first off they're very hard to mount on rims and they're almost impossible to mount on tubeless rims. I broke toe tire levers and pinched the tube about five times trying to get them on. In the end I put them in an oven at 190deg to soften them up and I was able to mount them and I used metal tire levers. I would run my other tires at 140 PSI and I ran these at 120 PSI and they run rougher. But they are a fast tire on smooth roads but they tend to run a little narrow than other 23s. My first week I did get a thorn which caused a flat but on the other hand the other people in my group got flats that ride as well on all kinds of tires. Overall there is stiffer tire and I don't feel as confident in corners and also one gravel they do tend to slide out. The price is good I don't know about the wear yet but I suspect they're going to wear a while.

Update to other review

I have them on 3 bikes and all are cracked after 2 months of use. Run at 120psi and they are nervous on cornering. I'll use the 8 tires I boughtv this winter and won't buy again.
