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! ;)

I would add Racing Categories, Medical Assistance, Course preparation, Timing method.

@PaulWeber: I suggest you edit the question to include the motives you state in this last comment.

comment Can I replace my bicycle's dynamo with batteries?
Yes @RoboKaren. That's why I would't worry. I've been playing with lamps, bulbs, leds, batteries, and ac since I was 10. I have disassembled may cheap led flashlight/torches and all of them had a resistor in series with the led, wich simplifies using the circuir on any DC source with the same voltage. Even have replaced kripton bulbs with ready made LED equivalents and no problem has arised.

comment What features of a mountain bike's geometry gives it different characteristics?
@DanielRHicks: The more "downhill oriented" a bike is designed, the slacker the head tube angle. Seems counterintuitive, but consider that these bikes tend to have larger travel forks and the slack angle positions the fork better for bump absorption at speed.

comment What effect does head tube angle have on a bicycle?
Is this a mountain bike or one with suspension? The angle difference you mention is very small, you'd need to be a very sensitive rider to actually notice the effect. IF this is a bike with suspension fork or a double suspension bike: Consider that the mere fact of having a working suspension produces head tube angle changes larger than 0.5degrees while riding, an no body seems to have problems with that, so, I would'nt worry over such a small difference.

comment Is it ok for the trunk bike rack to rest against the glass of a hatchback?
+1 For cleaning glass and feet before use. Rubber feet work better being clean and used directly. Plastic(ish) feet work beter cleaning and covered, as you say, with a sock or even better, some pieces of old inner tube.

comment Is it ok for the trunk bike rack to rest against the glass of a hatchback?
If you use it on good smooth roads, and with lghtweight bikes and you are a careful driver, then yes. Just clean the glass and the glass-touching part of the rack before use. But if the streets are like moon surface (like my country) I would look for another type of rack. Either a Roof Rack or a hitch mounted rack. Personally I had a Toyota Sprinter Carib and had the glass problem with my rack. Ended cutting the rack and using parts to make a customized one adding a few pieces of EMT tubbing.

comment Can a guy wear a woman's helmet safely?
I agree on that you better try them, diferent shapes can render a helmet unwearable. My oblong head would never fit a round helmet (BMX Style) because they would squish my head front-to-back while nothing would stop 'em from wiggling side to side. Test several to get the best fit!

comment How do I train for climbing in a relatively flat area?
Yet another suggestion: Even if you live in a flat area, if you can find a long stretch of a road that is straight and happens to have regular winds in certain direction, ride fast against the wind! (For example here in my country there is a windmill farm with a stright road across, almost every morning the wind blows in the same direction, and in the afternoon, it blows in the oposite direction)

comment How do I train for climbing in a relatively flat area?
@user12879: Indeed. I thougt of this a while ago, but my plan was (is) to use it on the neighborhood streets, not on the open road. Naturally, not to be used on windy days. Also the said parachute is really small, would not extend past the rear wheel, and when "deflated" would not hang low enough to get caugth in the wheel either.

comment How do I train for climbing in a relatively flat area?
What about a parachute? I have seen runners and soccer players training with a small parachute attached to their back. Creating air resistance would allow you to train on flat terrain. A small parachute can be easily made out of a piece of nylon cloth and thin rope.

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).
