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 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...

comment Uneven Disc Brake performance
Does this problem exists on both brakes (front and rear) or only in one of them? Also, did you try cleaning your discs with rubbing alcohol or a similar solvent?

comment For road riding, are mountain bikes safer than road bikes?
@Randy: on the other hand, I once had a puncture due to rim tape failure while commuting on an mtb, a slow leak that I hadn't noticed. When II tried to pedal hard through a crossing, the front tire whipped beyond my control and fell to the side, crashing a slowly moving bus's sidewall. Note thoug, that both anecdotes are about commuting, not sporting.tR

comment For road riding, are mountain bikes safer than road bikes?
@Randy: my logic is that skinny tires move a lot less when deflated, while fat tires are far more difficult to control when they have too little air. In fact, I rode my bursted tubes road bike 5 km (2mi) across my disorganized city and got to work on time, just had to avoid hard cornering.

comment For road riding, are mountain bikes safer than road bikes?
@ChisW: agreed on that. But I have had similar problems with rim brakes on mtbs. On my beginning I remained squeezing brakes all the way down, and fortunately did not blown the tubes but caused leaks in the valve stem-tube interface, wich gives a little more time to react. The reason I overheated rims on my road bike incident though was old, hardened brake pads. What I wanted to point out but didn't explicitly enough is tha sudden loss of air is more dramatic on a fat tire.

comment For road riding, are mountain bikes safer than road bikes?
Just an anecdote: I'm a @ountain biker, including dh racing so I'm more accustomed to mtb geometry and posture. I rarely ride road bikes, but this happened to me on a road bike. Descending a steeply sloped concrete road, braked too much, overheated rims an blowed front tube, an a few secs after the rear one. Despite the blown tires and the slight curve I managed to stabilize and avoid the crash. What saved me was the skinny tires. Had that happened with an mtb I has surely crashed and fallen under the passing cars.

comment Is it harmful to store a bike in a repair stand when held by the seatpost?
If you don't get rid of your concern, you may be able to make a cheap "adapter" that plugs in the seatpost clamp of your workstand and has padded hooks to hang the bike from the top tube or from the rims, sort of the type of rack used to haul the bike in a car's trunk. Yet another option is not to force the bike to remain "level", but let it drop the front end so its not subjected to permanent torque. But, this should not be a real problem at all.

@Aaron, you are right, my bad not taking a good look at the picture.

comment Leaking Slime inner tube valve after opened for first time since install
Just to clarify terminology a bit: the valve stem is the tubular part that goes through the hole in the rim. The stem is not removable, it is fixed to the inner rubber tube, the core is the removable part. All schraders have removable cores. Some prestas have, and an older style of valve, the dunlop, has a core that is removable by hand (no need for tools)

comment What accessories do I have to add to my bike so that I may commute during rainy weather?
And another shower cap for the head, I guess... And something similar for the shoes...

comment Any alternative use for old mountain bike tyres and inner tube?
Indeed. Cutting a stripe of inner tube and wraping it around "sensitive" points of the frame are a cheap but very efective way of protecting it from scratches. This is what DH riders use to do here in my country, as the bikes are frequently put very close one to another in a truck bed for the ride up.

comment Triple vs Double chainring?
I disagree completely about the triple being more complicated. I'm an MTB rider, all my bikes have triple chainrings, but the front derailleur and shifter is the less problematic one. I have to adjust a rear 10 or 15 times before I need to touch the front one. They even survive being ridden completely covered in mud for a couple of hours. The only maintenance I give them is throwing a little water, let dry, add a few drops of oil in the pivots. My average time between adjustments is around 10-12 months.

comment How to determine if a decline is too steep for safety?
As a part time DH rider, I fully endorse this anwer, specially the "Speed is your Friend" part. One of my techniques involves mentally dividing the trail in small segments that I ride without braking (or with very little). At the bottom of every segment I look for a "control zone", a less steep part of the trail or a patch of terrain with good traction, and really apply the brakes there. (This is what I call "pulsated" braking). The point is that these segments should be short, a few meter at a time, so you don't gain more speed than you are able to control.

comment Are there any generic hose extensions for frame pumps?
They exist, but are usually sold for a very old pump style, so they man not be readily available in all countries. The DIY approach may result cheaper due to shipping on certain locations.

comment If I can't find the hole causing a flat tire, do I need to replace the tube?
Once you find the puncture, do not forget to inspect the tire in search for the offending object. Inspect the tire casing very carefully, feeling with your fingers and in a well lit area to help with visual inspection. Inspect the inside and the outside. Many times, very small holes are caused by objects that became embeded in the tire but did not pass all the way trough, so they may be pushed further inside the tire wile riding, causing a new puncture very close to te old one.
