At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.
Good scores are more common than bad, because fortunately good products are more common than bad.
Zefal's Skin Armor S is a straightforward set of clear protective stickers made from reasonably thick polyurethane. They are easy to apply and do their job well to offer very impressive protection. Although with this small set the selection you receive is limited, you can get medium (£11.99) and large (£17.99) sets.
Back in the mists of time, when I was a young man and dinosaurs roamed the Earth, I took possession of a brand new Dawes Galaxy touring bike. One of the novel features about this particular bike's fantastic British Racing Green frame was that Dawes had started employing a scratch-proof finish, so there was no way it could suffer a surface wound. Needless to say, on my first ride out, I leant it against a lamppost outside a corner shop, the bike slid slightly, and it suffered a scrape that is still visible to this day.
Twenty-five years later, we have arguably a better weapon in the war against scuffs and scratches. Zefal's Skin Armor is a sheet of 'invisible scratch-resistance frame protection' polyurethane stickers that can be placed at likely rubbing or scuff points.
On the single sheet you are provided with seven stickers: one long clear protective sticker for the chainstay, two small-to-medium sized stickers, and four even smaller stickers.
To use, you simply unpeel a sticker and place it where you fancy onto a clean bike – it really is that easy.
On the front of the packaging you will see Zefal has handily included a diagram of suggested sticker placement points. Obviously, the head tube is a prime spot for cable rubbing while the chainstays are another old favourite (although new bikes tend to come with some protection already fitted). If you regularly carry your bike on a car cycle carrier or lock it up at a municipal rack, you may already have an idea of other damage areas. Once you've identified your preferred placement points, the stickers stick well and are effectively invisible. At 250 microns thick, they should put up a fight, too.
To put the Skin Armor to its ultimate test, I used a slightly tired bike that had already been in a few wars. Once I had fitted a Skin Armor sticker, I then made a concerted attempt to damage the frame finish by repeatedly introducing it to the sharp end of a brick wall.
Despite this approach being rather more extreme than you would suffer in typical daily rubbing situations – and it even ended up with brick dust left on the Skin Armor…
…a quick wipe of the sticker had it back to new with hardly any sign of battle.
As for the frame underneath – on this part of the bike at least – that's as good as new, too.
There are a fair few alternatives out there, with Evans having a similar sticker set for £7.99, Lifeline's Frame Protection Patch Kit costing just £5.49 for a wider selection of stickers, and Bike Shield having a range of options, albeit at higher prices. But I think in overall value for money and performance terms, this Skin Armor choice is pretty decent. You could argue a few more bigger stickers wouldn't go amiss, although for this you could buy the more expansive Skin Armor M or Skin Armor L packs.
Of course, sod's law is that the one section you don't place a Skin Armor sticker is the area where you'll have an unexpected extreme rubbing episode. But, as mother always said, you can only try your best. And Zefal's Skin Armor, for the money, is very good. Pick the right spots to protect on your pride and joy and you will have stacked the odds at least a little more in your favour.
Very effective frame protection stickers that are easy to apply and do the job well
