Mountain biker since 1999, I ride Cross Country and Downhill and anything in between. I also commute by bike some days(home to work and vice versa) in a very hilly city.

Started competition riding in 2008 national level in Honduras, Central America. I usually perform most of the maintenance and even major repairs in my bikes or friend's bikes. I own a small collection of bikes consisting of a road bike, one hardtail, three full suspension XC bikes and a DH bike. All of them except the road bike where assembled completely by me and none has ever fallen apart! ;)

comment What can I use for a DIY cable end?
Actually a crimpable connector would look pretty cool.

comment Why isn't my suspension bouncy?
@Alexander: yes, it can be helpful for some types of riding, however, they are more limited than frame suspension.

comment Dual air forks negative positive chamber pressure equality
I would too like to hear an answer for this question, however, I especulate that it doesn't matter that much, as the bridge that joins the two lowers of the fork mechanically links both springs. I get this from forks that only have one coil spring, or ones that have two coils but only one preload adjustment knob. I also use an air fork with one damaged side that leaks all the air in a few minutes, but the other side holds up all the load without any kind of complaint.

comment Don't integrated headsets wear out, ruining the frame?
I have a Schwinn Mesa lt frame that I'm sure uses an internal headset, and as far as I remember the cups come of just by hand. Does this contradict part of your answer or is my frame busted? (I've been riding it for 5+ years during wich I have installed two forks on it)

comment Bike left out in triple digit heat
The other statement is that a surface treatment does not protect seals, grease, etc.

comment Bike left out in triple digit heat
Indeed. I dont want my answer to state that treatments are not effective, but to state that too much exposure to such environment may exceed treatment's protection capacity.

comment What's the point in a freewheel/cassette with incrementally sized rings?
Excellent answer. MTB rider here. You need smaller gaps in the region you use most time. In my case, I have a hardail mtb with 11-34 and a full susp also with 11-34. But the ht has wider gaps in the lower gears (3 or 4 teeth) and 1 tooth gap on the higher, while the fs has an even 2 teeth gap in almost all the range. The result is that even though the ht is theoretically more efficient, I'm a much better climber on the fs, the ht helps me more when the gradients aren't so steep.

comment Safety check for a used bike
This is a very complete answer, To add my two cents I would say: Put on new tires and new tubes. Tubes get old and the material gets porous, slowly leaking air without being actually punctured, or can get "spontaneously" punctured. It's just too annoying. Also, replacing all cables is just correct. New generic cables perform better than branded old ones. I Also recommend changing the brake pads, as they get dry and hard with time, new ones are cheap, soft and flexible and will enhance braking.

comment What PSI for downhill bike tires used for road biking?
If the fork is adjustable, for road use, a stiffer compresssion setting, higher pressure on an air fork, locking (if available) and the slowest rebound setting, all help for pedalling (but not all forks have them).

comment What PSI for downhill bike tires used for road biking?
As I agree with this answer, I strongly recommend to change your tires to slick ones for road use, or at least ones with very light thread. DH tires or really knobby tires tend to swipe on heavy turns on the road, wich will make you avoid leaning, thus wearing only the center of the thread (wasting tire) and givin a less fun ride. Other than that, any tire should be able to withstand the max pressure on the label without problems.

comment Is a bigger wheel likely to get fewer flats?
Your logic is completely valid for tire wear, but if a sharp object was in the way of a tire, the tire will be punctured no matter how many revolutions the wheel made, it would only change the puncture location.

comment Which kind of tube valve is the best?
Almost all modern bike pumps have some sort of check valve to avoid back pressure, and many have dual purpose heads for presta/schrader use.

comment Does the age of brake pads make any difference?
I'm scratching my head trying to find equations that fit this case (Even though it's a bit apart from the OP's question) because indeed conservation of energy is absolute let's say the experiment begins a the top of the hill, I have potential energy. And I can descend and come to a stop at the bottom of the hill so all my potential energy was converted to heat, but with different braking techniques I get different heating for the rims and brake parts...

comment Does the age of brake pads make any difference?
Regarding whether overheating occurs: Indeed braking technique is a major factor, however, think of it the other way around: some materials are more "efficient" creating heat when being frictioned. I have conducted some testing in search for heating, and have found that different pads with similar performance can heat up differently, funny enough, my favorite pads (because of perceived performance) are also the ones that heat my rims the least.

comment Does the age of brake pads make any difference?
@KevinReid: Indeed it was not the dryness of the pads alone what caused my problem. I am very familiar with the road I was descending, which I always do with pulsed braking (usually on v-brakes, AL rims MTB) but indeed these pads would not brake enough, forcing me to apply greater and continuous pressure on the levers.

+1 for the trackstand.

comment Bike Lights: Helmet Mounted or Handlebar Mounted
Let's suppose for a minute that you have the handlebar torch and you have some sort of ankle strap for tucking your pant leg and keep it off the chain. You can use it to temporarily fit the torch to your helmet. Yet another option: some bike lights have flexible rubber mounts to fit the handlebar. Those can also be fitted to helmets of certain shapes.

comment Making a very sharp turn by pivoting on your front wheel?
In my humble opinion, this is more a show off than a very useful maneuver, because doing it with your brakes makes you loose speed (therefore, time). I know it can be done without braking because I unexpectedly performed it once, and it feel extremely cool. The alternative maneuver for sharp cornering is drifting the rear wheel. Can also be done with or without the brake. By the way, look for TRIAL bike videos, they do this maneuver (the one you describe) a lot!

comment How can a GPS with damaged screen be put to use?
It may be possible to find a second hand unit that has been damaged in some other way, but still has an operative screen, and perform the swap. (I did this a couple of times with blackberry phones, don't know specifically for your gps unit though...)

It looks similar to a Specialized Hardrock that a friend of mine owns...
