Avevo delle vecchie ruote da sistemare e mi sono fatto allestire un secondo set di ruote per la bici da corsa. Volevo una coppia di pneumatici da utilizzare su sterrato non troppo scassato (strade bianche) e/o in condizioni meteo perturbate ed ho acquistato queste gomme. Preciso che le utilizzo tubeless e ad una pressione di circa 3 bar. Le mie prime impressioni sono al momento estremamente positive: al prezzo di qualche piccola rinuncia in termini di scorrevolezza e velocità, si guadagna molto in comfort, sicurezza e versatilità. Provate su un tratto sterrato di un paio di km (una strada vicinale), mi hanno anche sorpreso per la loro tenuta su ghiaia. Hanno una mescola molto morbida, cosa che se da un lato favorisce la tenuta, dall'altro mi fa ritenere che vadano incontro ad un consumo relativamente rapido. Per certi versi potrebbero essere definite come delle gomme "ponte" tra bdc e gravel, utilizzabili su entrambe le tipologie di bici (a patto che il passaggio ruota lo consenta).Edit: Aggiorno la recensione dopo circa 6 mesi di utilizzo ed aggiungo una ulteriore stella (prima erano quattro). Ottime con la pioggia: ci ho fatto delle uscite con il tempo brutto e mantengono un'ottima aderenza anche in condizioni meteo avverse. Le consiglio anche per un utilizzo generico, da montare su una bici usata per la mobilità urbana o extraurbana. Finora mi pare abbiano mostrato anche una buona resistenza all'usura, nonostante la miscela morbida.

My wife and I purchased a pair of Aventon Level.2 eBikes last year for commuter and recreational purposes. They are great bikes and definitely worthy of consideration if you are shopping for a reasonably-priced and flexible-use eBike. However, as the miles racked up, it became fairly apparent that the stock tires just were not ideally suited to our area (Monterey Bay CA) and our typical use scenarios (commute-to-work on weekdays, and local greenways and trails on holidays and weekends). In a nutshell, many of the area greenways and trails consist of gravel, hardpacked sand, rough asphalt pavement, or a combination of all three. The stock tires on the Levels.2 are semi-slick in nature, which makes them a very good and fast road tire that also is battery-friendly. Unfortunately, they are nearly useless for anything other than street and well-paved greenway use.Because of that I almost immediately began to research potential tire options that were more-balanced in nature, with the goal of finding something that was still reasonably fast and precise on smooth pavement but also providing good traction and control if things were a bit looser. In reviews the Gravelking Sk + kept coming in towards the top for those requirements and they are available in an exact replacement size for the Level.2’s (27.5 x 2.10). Based on that I ordered a pair for my bike, with the idea of testing and evaluating them for a few weeks before investing in a set for my wife’s eBike (or not).After installing the Gravelking Sk +’s and doing a single 20 mile run, I immediately ordered a 2nd set for our other eBike. They made that much of a difference.Keep in mind dear reader, that tires for eBikes are like tires for cars. No single tire does everything outstanding, but it is possible to get one that does many things well, and this tires falls into that class. Inflated to 42lbs (small inside joke there, but it does seem to be an ideal default inflation pressure for these) these tires are surprisingly fast and precise on smooth pavement. Indeed, while not quite as fast as the stock Level.2 tires, their stiffer sidewalls make up for it by giving a much more confident feel in turn-in and maneuvering. And on dry sand, gravel, and gravel/sand combinations, they are simply an order-of-magnitude superior, providing a level of grip and control on those types of trails that would have caused the Level.2 pre-upgrade to quickly bog down or lose control. Being a hybrid-type design, they do begin to fail in deep sand and/or wet sand or dirt, but in my case those will be the rarest of riding situations so I did not need that level of aggressiveness in tread.Time will tell with regards to wear and puncture resistance, but the carcass of the Gravelking Sk +’s are noticeably heavier than the stock tires, so I would expect that they will hold up better.So, if you are looking for a tire that is more-balanced in capabilities than what you got with your Aventon Level.2’s without sacrificing much in the way of road-friendliness, these tires are definitely worth your consideration.

super tire 32 with grip very good

Guter, haltbarer Mantel. Nutze ihn tubeless auf meinem Alu LRS. Die genutzte Dichtmilch scheint nicht optimal (nicht explizit für Rennräder...), da an manchen Nähten im Reifen Flüssigkeit austritt.Hält den Druck aber einwandfrei.Reifen hat einen recht hohen Rollwiderstand, daher einen Stern Abzug.

I bought the 700x38 tan-and-black, which looks very classy and trendy on my gravel bike. Tire width is 38.1mm (both) once installed.I ride them at 45-50 psi, on both roads and hard trails, and have been very satisfied with comfort, efficiency and stability. Plus they appear to provide little rolling resistance (especially on the road) which is of course always appreciated.Contrary to other gravel tires, this one maintain a roundish look (between the sidewalls) as it doesn't have larger knobbies sticking out on the sides. This means a smooth transition from an up-right to a slanted (when turning) position. But it could also mean less grip while riding off-road, although not a problem on gravel and hard trails.I observed that the thread pattern in the center tends to hold on to small rocks and debris, which can be concerning regarding piercing through the casing. I haven't ridden them enough to comment on longevity and puncture resistance. But I do check them and remove debris after riding them, which is a bit more maintenance that I'd like.The installation was fair (on tubeless rims), although this varies (sometimes substantially) depending on the rims themselves and whether they are mounted with tubes or tubeless.No issues thus far. A great tire for road, gravel and hard trails riding.5/17/2021 Update: a tiny piece a glass made its way through the center of the front tire, between some of the small square knobbies, and punctured the tube as well. At that time I went ahead with new wheels and mounted them tubeless (quite easily, without tools) , after using a patch to seal the puncture. I ride them at 42-44 psi and they roll very smoothly.

These Gravelking SKs (which I got in 35mm tubeless-ready setup) proved to be a great all-around performer that were quite a bit more versatile than their name suggests! The tread's above-average grip gave me reasonable confidence commuting through Portland Oregon (where there's weaving through lots of rain, poorly-paved roads/glass and dirt paths) while managing to roll faster on solid ground than the vast majority of the stock tires on my previous mid-grade "hybrid" bikes. However, I did occasionally come across conditions beyond the SK's paygrade, as the wheels would spin a little over large patches of mud (which Panaracer apparently makes a more-aggressive version of the Gravelking for!).I otherwise never felt the need to change tires at any point of the year, whether it was riding through a crappy February or on a longer off-road summer touring trip (as they provide an even plusher ride at low pressure on top of their reliable grip). While the Gravelkings did (thank goodness) prove to handle quite soundly on full-gravel rides as well, be aware that it does (probably in part by design) tend to chuck pieces of gravel up and around your tread, so you'll want to have some space between fellow riders (and preferably have a decent coat of paint to protect the finish of your bottom bracket!).My only real criticisms are Panaracer's seeming lack of attention to the Gravelking's implementation as a "tubeless" tire, which were VERY tricky (read: pain in the ***) to keep seated with my original rims, and I found it odd that they didn't bother to demark the tubeless capability anywhere on the tire (despite confirming with both Panaracer and my awesome Local Bike Shop I in fact did not receive the wrong version of Gravelkings in the mail). That said, it's admittedly hard to complain too much given the general performance and value, being fairly priced for a high-quality made-in-Japan tire!Update: After holding up to 18 months of moderately-vigorous riding (which while not by any means a rock-hard beater-tire, is considerably greater longevity than many other respectably gummy-grippy tires in its class like the Maxxis Rambler), I was compelled to get a new set of the Gravelkings (same spec), which I can happily report has resolved the tubeless labelling issue, and handles every bit as well as I remember the first pair I bought! I wish you happy rides with this tire as well :-)

Excelentes llantas para hacerlas tubeless. No me han dado ni un problema, las he usado en pista y offroad, rendimiento maravilloso, en las vueltas con piso mojado se deslizan un poco, pero es de esperarse, no están diseñadas para eso. Le agregan mucha estabilidad a la bicicleta, pero la hacen más pesada. Ten cuidado al comprar, yo me fui como gorda en tobogán al comprar las 700x50 y casi no le entraron a mi bicicleta, de no ser porque de fábrica tenía in espacio extra. La mejor opción, a mi parecer serían las 40+ pero eso depende mucho para qué las quieras, gravel, piedras, camino, descensos técnicos, todo lo pueden estas llantas.Encima se ven increíbles.

I was sent the SK version in error as I had wanted the slicks originally. However it worked in my favour as I decided to keep them. The SKs for small knobs are an excellent all-road tyre. Im running them for a mix of pavement, rough roads, double tracks, and gravel. I don’t feel I have much drawback on the blacktop other than a bit of a whir sound at speed but they don’t feel slow at all. They really shine when I go exploring and go down side roads and trails, I don’t have to worry.Overall they are a great tyre and I don’t see much need to run a different set for the vast majority of my mixed road riding.
