i'm not familiar with the brand, but the tube will fit an 11.2-28 which by the way is the new number for the old 10-28... 12.4-28 is the new number for the old 11-28
not uncommon for one tube to fit 2-3 different tire sizes.
I have seen front tubes fit 5.5, 6 and 6.5-16 tires.. etc.
at 24$ for the tube and 15 shipping ( wow.. ).. it's 39$.. which is certaintly about 13$ from the next cheapes ones I could find.. with most costing about 70$ shipped, on average.. and one low to mid price of 57$ shipped anywhere in the co-us.
looking at the tubes it certaintly looks no worse than the others I saw, perhaps not as beefy as some.. but way better than at least 3 other more expensive ones I saw.
can't be much worse than the larin I'm usualy stuck getting from tractor supply when I'm in a pinch.
me miller tire co has the tube for 38$ plus ups shipping... etc.. so .. the website is darn cheap.. etc. if it holds air.. and that's all it has to do by the way... it's pretty economical..
