Mongoose Dolomite Mods

Wide-tire bicycles with flotation are great in snow or on sand.

LBS sold me tubes to lighten up my dolo. Think they sold me wrong tubes. Got 26" 2.50-2.80. Said they would inflate up to fit tire. Im not buying it. Gonna return them.

lol.. The tubes would probably work, but the weight difference would be negligible and the thinning of the material could possibly be a problem. If they hold air now, you should be fine. If not, those tubes would get you back to riding. Seems to me though, going to a lighter tire and maybe tubeless when you do, would most likely make a very noticeable change. Tubes alone? I doubt you could tell the difference in the weight while you ride

The bike store sold you the correct tubes for your purpose. Many, many, many people on that "other site" (everyone can gasp now, but there is a ton of useful info on "that site") use these tubes (I assume they are Q-Tubes Superlights). I use them as well and they weigh somewhere between 212-230 grams I believe which is way less than the stock tubes. This will decrease your rotational weight but until you change out the heavy tires the tubes only provide a minor improvement. But when changing tubes and decreasing rotational weight by 1 pound or more that is significant.

The tubes will expand to fill a 4 inch tires without issue. I have even run them down to 5 psi without issue.

Ok. Thanks, I guess I don't fully understand running them on such low PSI, 5 PSI, but will give them a try. Now thinking of going tubeless, they do have rim strips in them. IDK, probably just gonna ride the dern thing!

The OEM rim strips (or any rim strip for that matter) do not provide a good enough seal for going tubeless. You will need to do some research on the best methods for going tubeless on the fattie, like using Gorilla tape for instance.

The lower the psi the more traction and "float" you will have over soft surfaces such as snow, sand and mud. It increases your contact patch and distributes your weight better.

On hard pack trails I run higher pressures.

And despite what others on this site may say, I WOULD recommend reading the "The Dolomite in the (semi) wild" thread on MTBR.com. Why limit yourself to one site when there are other people with your bike on another forum that have a lot of great info as well.

Nothing wrong with getting info from multiple places.

Thinking of cannibalizing one of my other bikes. Has shimano acera crancks and gears and derailers. Will these work? Is this worth the trouble? Will they be an improvement on the dolo?
