I have a Grossman bike, and my seat tube is abit highAs i am riding street, i need it to be lowerI've put my seat post all the way down but still, when i'm riding, it feels as though im riding a Xcountry bike.Need help guiding how to cut the seat tubeShould i?
maybe you can go to some can factory or to a recycling place they should have some cans there or go to a local craft store they might have something there i still say that rubbing the cans with sand paper is a good idea maybe get some friends to help you out a bit you can get alot of work done with team work ok i hoped i helped good luck ;D
A grossman is a nice ride why wreck it? Can you sell the one you have and buy a trial style frame? It is considerably shorter than the FDT stylesPersonally I would do my best to never cut a frame, but that being said here goes 1.) If you are looking at selling the frame ever, then, noBuy one that fits and is shorter2.) Make sure the seat post is not hanging up part way down and that you are actually able to put it as low as possible3.) Since you are street, I assume you are not sitting but rarely between trix or attempts, have you tried a low profile seat? Some of the trials style seats have very little pad, are much smaller and sit lower on the post4.) If you only intend to do street and it is your frame for life, then go ahead (CAREfULLY)If the seat tube is tapered, you may need to shim it for snugness when doneAluminum can strips work awesome for thisAgain, make sure first that your seat post actually goes all the way down and is not stopped inside the seat tubeIf the seat tube protrudes above the toptube too far (and the seatpost is not the issue), you can cut it off square with a hacksaw leaving at a minimum 1 of tube above the toptubeMake sure to dress the inside and outside of the cut when done with a round file and emeryThen cut a slot (easy with a dremel tool) in the backside of the seat tubeMake it at least 3/4This will allow enuf room for the clampGo slow and try not to overheat the tubing as this will weaken it moreMeasure three times and cut only onceIf when you measure it, and you estimate it is still too tall then I would say your frame is too big for youGood luck!
