CYCLO Chain Wear Indicator for Bike Chain Maintenance - Accurate & Easy to Use

Yes the edges might be a little sharp but it is not a spanner, so you are not going to be handling this with any force at all where is is likely to hurt your hands. The markings are easy to see, it is made in the U.K. in the neighbouring town to where I grew up, and is super simple to use. It drops into the chain links on all my bikes and kids bikes very easily and gives an instant measure of wear. While a bike shop or pro might need a more expensive measure, this one is absolutely fine for nearly everyone else. Recommended.

nice easy tool to keep in my kit. I now know when I need a new chain rather than guess when I need one. Thanks Len.

While looking around for a chain checker, I was immediately puzzled by this one. Why does it have long spikes when all the others just have a short nub?It turns out that the long spikes are what makes this one better than all the others. Where the others can basically only give you a "yes" or "no" answer as to whether your chain is .75% or 1% stretched, this one gives you an indication, if the answer is "no", of how close you are to that value, by how far down the spike will go. So you can get an idea of whether it's likely to need replacing soon, or not for ages, and thus, how soon you should check again.Accuracy seems good. One of my chains needs replacing and it showed that by the spike going all the way down. The other two don't need replacing yet, but one of them is almost new and the other is part worn, and I could clearly see the difference between them on this tool which I don't think I could on one of the nubby ones.It's a bargain given it could save you £££ on premature chainset/cassette wear; highly recommended.

Having put a new Shimano chain on my bike I thought i would get a gauge. Bought a cheaper non bike brand and it was showing the new chain as stretched so returned it and bought this one. Now have an accurate and still low priced gauge.

Fast delivery!!! Very useful tool homemade basic mechanics. It gives a good idea about the condition of the chain. I use it to check the chains of my 2 bikes frequently. On my experience even when you reach the max indication which is 1%, you still can use your chain and cassette for a quite few miles with no headache before they wear off completely. I recommend it!!!

It’s very basic but it will just about do.

Handy but expensive! Be sure to sand down the edges, they're quite sharp!

Not a great deal to go wrong here tbh, simple tool but worth having as part of your bike tools, this item is well made using decent stainless steel material (not sure of the grade) but feels good, engraved either end with 75% & 100% wear indicator, all in all well made with no sharp edges. Packaging & delivery as described by seller. Will definately recommend.

Mir gefällt diese kettenlehre sehr, da sie einen bereich anzeigt statt nur einen binären wert.

Utiliser pour mesurer la bonne tension de la chaîne de vélo.

Me encanta, buena relación calidad precio, cumple a la perfección con su misión

Prodotto molto utile per controllare senza difficoltà il livello di usura (in termini di allungamento delle maglie) della catena così da evitare usura precoce di pacco/cassetta pignoni e guarnitura. Da notare che le stesse misurazione sarebbero eseguibili anche con semplici righelli o altri metodi empirici, semplicemente l'operazione sarebbe più complicata e meno agevole.Presenta due indicatori a 0.75% e 1.00%.- Se utilizzando l'indicatore 0.75%, l'indicatore entra interamente nelle maglie, la catena deve essere cambiata ma il resto della trasmissione non risulterà compromesso.- Se oltre all'indicatore 0.75% dovesse entrare anche quello a 1.00% allora la sola sostituzione della catena potrebbe comportare salti e slittamenti della trasmissione. In tal caso sarà probabilmente necessaria la sostituzione di altri elementi del gruppo cambio.Consigliato per semplificare la manutenzione di cambio e trasmissione.

Too fait le boulot, bonne précision et bonne qualité
