Zefal Kit Anti Puncture Hybrid

Answer of Zsolt

Hi! The package what I got differs a little bit from what you can see here on the picture, and it actually says the tire size recommendations for this product. It says : from 35 mm to 42 mm. On the Zefal site you can see the tire size recommendations of the different puncture protectors. According to this, for the 47 mm wide gravel tire, they recommend the blue MTB version, which is the 34 mm wide tape, 90 g per piece. Hybrid / Gravel 35 mm, 38 mm, 40 mm: organge/ 27 mm. Road 23 mm, 25 mm, 28 mm: grey/ 19 mm. MTB 2.4'', 2.6", 2.8", 3.0": purple/ 50 mm. Hybrid / Gravel 47 mm, MTB 2.0'', 2.1", 2.2", 2.25": blue/ 34 mm. In case you'd still want to choose this orange Hybrid version to save grams, (this 27 mm wide tape is 60 g per wheel) to avoid circumference issues, I've measured the length of this orange tape. It's 224 cm long per wheel. (| own the gray Road version also, and that is 224 cm long as well, in case someone wants to know.) So if you'd still choose this, you'd have to measure, and find out that 224 cm is enough or not, because it seems borderline. Maybe you'll be able to overlap a few millimeters. (The blue MTB tape must be longer, you know, for 29 inch tires and stuff. I dont own that.) Even though they recommend to leave a gap, and not to overlap, personally a would not leave a gap, I would overlap, and if it creates a hump too big, then i would try to cut it to a perfect fit.
