Ive been riding on these tires for years. Loved them. Have gone through 8 or 9 sets. Most recent purchase, and as others have noted, rubber is failing. Had a front where chunks of rubber came off and a rear that did the same. All at around 900-1200 miles. Something is wrong with production and will not purchase until I hear of product being improved.
Been running these for three years now along on two
high end road bikes . First set lasted almost 5k with only two flats , Replacements since only have lasted
2K before wearing out and producing regular flats .
Lots of small cuts everywhere and one sidewalk failure . They roll really well but puncture resistance and wear dont stack up against Conti GP 4000
These tires roll and grip quite well especially in the wet but I cannot get a set to last more than 1200 miles. This is a tire thats marketed as an all rounder e.g. GP4000 s II or Rubino G (granted this is more on the training side of all rounder i should mention that I used to get 6-7000 miles on those). I put these on some lighter weight aluminium rims I had laced to a Powertap
I picked these because I was in search of a training tires that I could race a weeknight crit on since swapping for race tubies is a pain to do. They crack and slice really easily I havent had a catastrophic failure but thanks to the topography here I pretty much will always hit 50 mph on every ride so I just cant take risks with tires that have holes in them.
I am a cyclist and have used Schwalbe road tires for the last 5 years. I recently bought two new tires for my bike. One tire was defective. The tread began to separate from the casing. I had only rode about 30 miles before the tire fail me. It started out as a small bubble and graduated to about two inches in Diameter look like balloon stuck to me tire.
