I was wondering if the front axle on my mosh brass one star gold is chromoly or not. I am bending it from stalling to hard every now and then. Should I get a heat treated chromoly one and will it hold up? I am also wondering about threading. What is mine 26t or 28t?

26t is the correct threading.
It probably is a steel or cheap chromoly axle.
A heat treated 4140 axls from Kink or Standard will do MUCH better for you than a regular cheap axle. I used to go through front axles once a month (at least) and then switched to Standard axles and the FIRST axle I got from them is still not broken.
Oh, and I got that axle TEN YEARS AGO. Yeah, I saw a major difference with 4140 heat treated axles.

or the more costly version, get a new hub with 14 mm axles in it, fit that in ur rim and spokes and get some one to cut the front fork to fit the axle, seriously, its not a bad idea.

cutting the dropouts on a fork IS a bad idea, I still remember the day when people would grind their rear dropouts to fit in those bulky 14mm axles. I just bought my first bike with 14mm axles not too long ago and I must say, having ridden only two bikes with axles larger than 3/8 for more than a few weeks at a time, if you're smooth and you run the standard axles your bike will love you!!

there is nothing wrong with cuttin those out to fit bigger ones, wat could happen?
nothing, if u have a chrmo fork and a torch itll be just fine, wat do u think the factory does, but if ur wrryd then go get some 4140 axles

I have an older frame that had a 3/8" dropout and I grinded it out to fit the 14mm axels on the new hubs i got. I thought it may weaken the frame but i have taken some pretty hard landings and nothing has happened yet. (By the way i still run a 3/8" on the forks) My suggestion is if your going to grind out the dropouts only do it on the frame and do it equally on the top and bottom as to not put to much stress on a certain side. Also do it slow so you dont warp the frame. I say dont do the forks because the are made much weaker than the frame so it is more likely that they would break.

small suggestion, slotted axled for the rear, and you will weaken the front dropouts by cutting, just get a new fork! Whats $80??? mowing a few yards? A weeks part time pay at a fast food joint?

ONCE AGAIN:
People keep saying "cut, file, drill, grind...."
DO NOT DO ANYTHING TO YOUR FRAME UNTIL YOU TRY HEAT TREATED 4140 AXLES!
A lot of riders I have spoken to have said that they have used Standard axles and then switched to 14mm. The problem they had was they couldn't get good heat treated 14mm axles, so their 14mm axles ended up being no better than their old heat treated axles - sometimes worse. They were out the money and time because of building up a new wheel, and they were no better off!
Don't be a sheep, try your options with what you have first. 13 bucks for a good axle... definitely worth it.

everyone that says dont grind or cut ur frame is because all of them seem to have done it themselves, if u know how to do it right then it would be just fine but im sure most of u dont have dads that could do it right like mine, so ya i think new fork, or those 4140s

I believe dropouts are made to fit the size axles they come with. I do not want to do any grinding on my bike. I plan just to get a heat treated axle. Thanks guys!!!

I also hope to eventually get a new front fork. It would be nice to stick with 3/8's so I don't have to worry about a new hub. I might just get the Mosh Brass 4 star frame from www.danscomp.com. It is Marcus Wilke's pro frame... or so it says. It looks really solid not to mention I could use the leg room. lol I hate my 18.5 top tube since I am 5' 11" and have long legs. It is not the lightest frame but its on sale for really cheap!

I rode 3/8" on my back for the longest time, and I'm not a small guy, I broke an axel practically every two weeks, but i was too stuborn to get a new hub, I eventually got a primo pro casstte in 1/2" and I couldnt wait till I got my new frame so grinded my dropouts, and it turned out just fine.. i eventually got the new frame.
