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 Should one pedal over a mild slope?
It greatly depends on whether you are racing (or trying to beat a personal mark) or just "need to get there". After that: there is a certain speed above wich it's better to adopt aero position. It must be determined empirically for it depends on circumstances. bicycles.stackexchange.com/questions/24372/…

comment Can I use WD-40 on my bike?
It greatly depends on bike usage. On clean roads a light lubricant is good. On dusty/muddy conditions they all struggle, but on intermediate situations is where you can see the difference in quality.

comment Can I use WD-40 on my bike?
@jimirings: I agree that they have a solid name and a strong trademark, "WD-40" and the good-for-bikes debate has already done a lot of marketing and advertising for them, so I think it is a logical move to jump into bike specific products. I also think they are pretty new to the market, I jus saw them forst time less than a month ago...

comment Can I use WD-40 on my bike?
@Batman: I have used 3-in-1 for a time and I can assure that at least over a period of a year it won't gum up (so I don't believe it either), however there are knock-offs and look-alikes that do. The downside of 3-in-1 is that I have to re-apply after each ride, where other lubricants (bike chain specific) last 3 or 5 rides.

comment What's the purpose of cycling gloves?
Gloves are less likely for road riders partly because they have several hand positions and they have bar tape. Other bikes, like MTBs only have one hand position and it is usually lined with a rubber grip. This makes sweat acumulate, thus turning the grip slippery. A glove helps with this situation a lot, since many of them still provide enough friction enven when soaked.

+1 Just because I have the same exact sutuation.

comment Front wheel bent
If it is a cheap steel rim, 1cm is esily trued just by adjusting spokes. Cheap Singlewall Steel rims are very flexible, it does not take a lot of force to bend or unben them, so the spokes wont suffer.

comment How to select gearing for descent?
It is almost imposible to generate significative acceleration with only 1/4 of a turn. I have observed that a quick burst can be obtained with 2 or 3 pedalstrokes (1 or 1.5 rotation) over the span of aprox. one second or slightly more. That means a cadence of around 60-100 rpm. I choose my gears to be in that range. If the section is too short or too tough to calculate 2-3 pedal strokes, then it is better to focus on picking the optimal line.

comment Difference between road & mountain drivetrain
@Alexander: If you are talking about taking a fully assembled mountain bike and fit it with road style handlebar and shifters then yes, it is possible. You would need to pay special attention to levers and shifters though. Your brake levers should have the same pull ratio as the brakes on the MTB and the shifters have to be for the same gear count and pull ratio. These levers exists, for the very same purpose.

comment Why is it important to keep equal number of turns when building a wheel?
Counting turns does not take into account possible diferencies among spokes or among nipples, something very likely on low end ones. Another factor may be te fact that some spokes are head-in and others head-out at the hub. Also, this doesn't take into account dishing like for a front disk brake hub or a rear hub for a high cog-count cassette, SO I may say that couting turns is not a rule but a guide line to apply at the beginning when there are still spokes missing and before any of them gets tightened. I'm no expert thoug, I have built 2 wheelsets from scratch.

comment Tips for having partner drive support.
@Kibbee: You are right, but this is only one of the many scenarios that may happen. The planner of the ride shall modify the particular strategy based on how likely it is that these type of failures happen. What would be the solution if the car and one bike breaks in different points of the route? The support car shall pass a mechanical revision prior to the ride, as shall the bikes.

In this answer I cover the basics of brake adjustment: bicycles.stackexchange.com/questions/9889/…

comment What causes brakes to perform worse when the bike is loaded?
You are listing symptoms of misadjusted brakes and/or old brake shoes. You mention that you have performed part of the required maintenance, but you must go all the way and change the pads and fine-tune the system. I also recomend washing the rim's braking surface with kitchen soap and dishwashing scrubbing pad. An answer already pointed to an article on adjunsing brakes. Several other questions on this site cover the issue as well.

comment How to destroy a LOOK pedal as it won't come off anyway
please do not use driver/passenger side references, as this will be misleading for people in england or other countries where they drive on the left lane. ;)

comment Hub grease, white grease, red grease or buy grease?
Unfortunately you don't know for sure what the red grease was for. I use a red (red berry juice like) grease that is designed for automotive bearings and tolerates high temperatures (It has lithium on it) and it does a terrific job. Some greases instead of decomposing just separate a little from the dilutant, mixing it again solves the issue.

comment phantom leak that fixed itself?
Adding to Vorac's comment: if that didn't show any micro puncture, re-install the tube and pump it up to the highest safe pressure marked on it and submerge the valve part on water. A faulty valve will not leak but under high pressure.

comment Cleaning Carbon Black off a Bicycle
I regularly clean my rims with kitchen soap and a dish and cookware washing pad (the green ones that are roughly 4"x6"). If I do it soon enough it doesnt require much scuffing and avoids this black paste buildup.

comment Is it preferable to pedal downhill?
@CareyGregory: Thanks for your feedback. I placed the only example I have numbers for, and it happens to be a mixed case, bcause it's from an MTB ridden on asphalt. I have ridden the same roads on a (very) old road bike, and I know my treshold is around the same speed but my "aero" speed is much higher due to less rolling resistance, unfortunately, I don't have a computer on all my bikes. I will edit when I get better references.

comment Is it preferable to pedal downhill?
Can you please clarify if you are asking about Road Racing or MTB racing? Since strategies can differ vastly among these disciplines.
