Good tube for the price have had on my bike for over a year and was at the track and must have pinched it, and caused a flat. But for $10 a tube i got my moneys worth easy to install. If you're worried about flats just go with the ultra heavy duty tube. If not run the heavy duty they will not disappoint.
I measured these against the Kenda Tuff Tube and IRC Heavy Duty, These are by far the the thinnest followed by IRC, with Kenda almost 1/3 Thicker. I can't say if they are better material or construction though. Good price.
The tube was quite durable. Except for when I inflated my front wheel, the tube had blown a hole. No worries, I just patched it up and secured it with heavy duty tape.
As always sti tubes are way better than stock and are actually twice the
The thickness as OEM
Seemed pretty thick time will tell
Installs like any other tube. Thickness add a little complication. Survived my mangled attempts to install the tires. This plus 8oz slime continues to hold air, which is all I can ask.
This thing is built to play. Nice and thick tube goes right in, and and as always motosport.com did an awesome job with customer service. I most definitely will order again and again for all my riding needs.
It's a tube, so not sure what to say? It holds air, installed easily without pinching. Seemed to be of good quality material. Only one ride on it, but no problems with it, I am sure it will last to my next tire change. I always throw a new tube in when I do tire changes. Better safe then sorry!
I have 10 dirtbikes that cover my family of 7. I change tires, lots of tires. Little bikes are the worst so any product that can limit my minibike tire changes is so worth it. These tubes are super heavy duty and no problem to install. We ride alot in rocky terrain and also the adults use the minibikes as pitbikes so they get a workout. I highly suggest these tubes, great value also.
Fast parts delivery, exact parts match every time,
great tube great price me and my buds luve these tubes no flats great price
Man this thing really holds air, even better than my guts!
went on couple of rides no problems
It's thick. It's black. It's rubber and it's round. It serves its purpose and does well doing so.
I brought these tubes for a recent tire change. They are great quality and you can't beat the price. Will buy some more for spares.
Sti makes a good tube at good prices.
excellent tune can with stand rough terrain and saves u money from buying tubes over and over
The valve stem caps they supply does not remove valve stem. Keep going back to the metal ones. It is a waste of time if you have a flat and don't have a metal one with you.
...but this is definitely better and stronger than stock. Maybe an oz or two heavier, but I'm not paid to ride. Give me durability any day
Shipping is calculated in your cart at checkout. UPS is our preferred shipping service and we can NOT ship to PO boxes. We have to have a physical address.
For a 2.75x21, you can use any tube from 2.50-3.00 with varying pressure.
For a 120/80x18, you want at least a 4.00 tube, but preferable a 4.50 or a 5.00. a 120 rim is about 4.75 inches wide, so you want a tube close to the same width.
