1. The most important thing about buying a new bike is to make sure it fits. The only way you'll know if the bike is right for you is to size up the bike and make sure that the bike's geometry matches your body's geometry. Ask questions and do some research.

2. If possible, try to find a shop that will let you demo the bike on real dirt. Five minutes in a parking lot won't cut it. You wouldn't buy a car without a real world test drive, and a bike should be no different.
3. Don't belive the hype. Just because your favorite rider or best friend rides a certain bike, that doesn't mean that's the best one for you. Have an open mind and be realistic about your needs and ability.

    Shimano Disc?

    Hello! I finally got 2010 GF Marlin (no disc) couple weeks ago! I was thinking about getting disc brakes for it and I think I need to get Shimano ones unless I change the wheel set...which I don't want to do. I don't know much about Shimano Disc brakes so if anyone here has suggestion or helpful hints, that would be greatly appriciated!!!!

    If it's centerlock you're worried about, they have adapters.

    Or you could buy the brakeset and rotors separately.

    I have a set of XT hydros and they work great. They require Shimano Oil which can be pricey so I bought a bargain jug of 1 litre to last me a lifetime...or two.

    What about getting Shimano disc brakes makes it so you wouldn't need new wheels?
    Do you have CL hubs already?
    Honestly... ahh I give up

    Yes, I think it is Shimano M65 CenterLock disc hubs. So I was thinking about Shimano disc brakes... but I have no idea which ones.....

    I you have centerlock hubs then you can get a shimano center lock rotor, and then get any other caliper, just make sure the rotor size and the brake adapter are the same sizes.

    Nothing wrong with Shimano brakes, work well, last a long time...

    Shimano requires that their brake systems use their own formula. Don't ask me why, I don't know the details...but rather than risk damaging the brake system with typical mineral oil...I took some advices from others who use Shimano brakes and went with the Shimano oil.

    Thanks guys for quick responses! I was told from friends that BB5,7's are pretty good. What would be equivalent disc from Shimano? Anybody? (I hope I'm not asking stupid questions...)

    You're going to get different brake performance because the BB5/7 are mech disc and the Shimanos will likely be hydro.

    The BB5/7 are great performing mech disc but I moved away from them because I didn't like the on/off characteristics of mech discs. The pressure being applied to the levers are directly transferred to the discs so it is less dynamic in performance.

    The hydros are pretty much similar to car brakes sans booster so the performance is more dynamic. Some people complain that it's "squishy" or "lack feel" but I found it to be better on techy down hills and rough areas than the mech discs which tended to lock up due to my lack of lever control.

    You do what you want because they're your brakes, but I personally would not have any qualms using medical/food grade mineral oil from the drug store.

    It kinda seems like a recipe on the back of a box from brand-'X' telling you to use a flour or butter etc. of the same brand.

    And you have no business talking about brakes anyhow Mr. Jake

    P.S. Stay away from Shimano M485 calipers. They are crap. Try to obtain Deore LX or better.

    LOL....that's right! I use my fingers!

    But seriously tho...I was having same issues with my CODA brakes and was getting the same 50/50 split on opinions.

    Supposedly CODA uses a special formula like Shimano but they call theirs "NASA developed brake fluid" or something like that...and for both brakes, half the people were claiming that regular mineral oil would destroy the seals and half were saying it wouldn't.

    I guess I'd rather travel the safe route.

    ....ANYWAYS...I don't use brakes! I use my FINGERS! MUAHAHAHAHAHA~

    ?

    He was talking about getting the Avid BB5s. Aren't the M416s comparable to the BB5s?

    I know they're nothing like the BB7s, but...

    OK. I'm no expert and supposed expert opinions are split pretty much 50/50 on Shimano Oil and alternatives. Mind you almost everyone agrees that grocery store and hardware store mineral oil is a no no.

    So tell me...why not Shimano oil.
    And I hope you're not gonna start telling me that I can use DOT brake fluid used on Hayes brakes system for Shimano brakes as well.

    While you're at it, I have a set of CODA brakes and I obtained a rare set of CODA specific bleed kit with CODA fluid. Did I make a mistake on this as well? What alternatives can I use?

    Like I said, I'm no expert so expert advice will be helpful.

    I would also like the chemical makeup of all the fluid that I can use on the Shimano and CODA systems. (that would be CHF, HSMO and Magura Royal Blood for Shimano and no known alternatives for CODA)

    Also I would very much like to know the reason for Shimano Oil's red color rather than the typical clear color.

    Can I use CODA oil on Shimano brakes and can I use mineral oil in CODA brakes and can I use something other than DOT fluid on Hayes?

    Please answer every question with sincerity.

    Thank you.

    Bb7s all the way if your considering mechanicals! There is other types of fluid that's compatable with shimanos system. I run avids on my bikes so I can get dot fluid from pretty much any where.....

    You can pick up Avid Juicy 3.5s or 5s for $90-$140. My GF can with the 3s mounted on Shimano hubs but they are different hubs than yours. These are great brakes. They use DOT brake fluid so you avoid the mineral oil debate occurring above. I would have preferred using mineral oil because of environmental reasons but no a big deal. Hydros are require little maintenance unless you get air in the lines. The feeling of the levers is much more linear than cables IMO.
