comment Fatbike tire footprints?
I don't think the photos were taken at the same distance, therefore they may not be comparable.

comment Brakes feel like they are not even there on my used road bike. How can I fix it?
Are the rims steel (check with a magnet)? Where the rims wet? That combination has zero stopping power.

comment Wear and tear and warranty
@nettux443 - Lubing the cassette will only attract dirt, which will accelerate chain wear. The only possible reason to lube a cassette is to reduce rusting on lower end components, even then the dirt it attracts is worse than any rusting. After lubing a chain, let it set in then vigorously remove ALL external oil. You only want to oil on the inner surface of the roller.

comment why change gear and brake cables?
Water intrusion into brake cable can cause quite fast deterioration. I have seen brake cables with substantial rust in just a couple months of wet weather riding.

comment How long between spoke adjustments on a mountain bike?
@Vorac if you have a high-quality rim that can withstand high spoke tension. Even then under high vibration and load spoke nipples can back off. Spoke prep exist reason.

comment How to prevent shifting issues due to derailleur or cables freezing in cold weather
+1 for chasing the water out of the cable housing, but what will hair drying the derailleur accomplish? It is unlikely ice formation in the derailleur will affect shifting, and if it did it will simply re-occur on the next ride.

comment How long between spoke adjustments on a mountain bike?
They may have also forgot spoke prep, combined with insufficient tension, would allow spokes to loosen off.

comment If I use an 8 speed bar end shifter with the TT bar on my Allez, will I need to change any other parts of the drive chain?
You can run SRAM by using the 8-speed bar end shifter in friction mode (without indexing). Most bar end shifters have this mode (except for the 10+ speed Shimano bar end shifters).

comment How can we calculate the efficiency of the Siva Cycle Atom generator?
I calculated 20 watts drag as well. My Schmidt dynamo hub has a quoted efficiency of about 65% at 15 kph. At 30 kph the drag is about 6 watts. 6 watts of drag is barely noticeable, but 20 watts of drag will start to feel like riding on a false flat.

comment Can tubes be used in tubeless rims aswell as tyres?
Do you know if there are any tubeless rim standards that are not compatible with clincher tires?

comment base training with or without added energy?
@Johan - Note that eating before exercise will basically undo the benefits of exercising in a fasted state (see De Bock 2005, De Bock 2008). It's either all in or avoid.

comment Mystery grease source - Alfine 11, Gates Belt drive, Shimano bottom bracket
For slipping check the shifter cable tension as well as look for housing that may be caught/pulled out of place. My Alfine deteriorated fairly rapidly after 2 years, hope you have better luck!

comment What is the advice for new cyclists?
As you successfully finished a 200 and 300 km event without any notable concerns (at least not specified). It is unclear from the question the type of advice you seek/need or if you need any. For example, where you unbearably uncomfortable during the event? Did you have problems managing food and water? What are your long term goals (e.g., 600 km, 1200 km)? Do you have any concerns for meeting these goals? Without any guidance this question is overly broad, unanswerable, and is more suited to a Ranonneuring forum which encourages general discussions.

comment Light for Tubus rear rack
@JohnZwinck - It is a shame dynamos haven't taken of in North America. Won't commute without one!

comment Light for Tubus rear rack
@Blam - Both linked lights require a dynamo to power the light. The Busch & Müller 4DToplight Senso Multi can be powered by batteries or a dynamo source. See peterwhitecycles.com/taillights.asp

comment Should one buy a used Brooks saddle that is already broken in?
@BenjaminMakoHill - I have updated the answer. I probably should have edited the question when I saw the mistake, thanks for contributing!

comment Coping with crash fear?
Great answer... I laughed at riding at the back of a crit to "avoid" risk. So many do it, the irony is so thick you can cut it with a knife.

comment How does weight and strength of a person effects the riding of bicycle at higher speeds?
Optimal cadence (in terms of metabolic efficiency) is a bit of a myth. There is a huge capacity adaption by skeletal muscles. See McDaniel, J., Durstine, J. L., & Hand, G. A. (2002). Determinants of metabolic cost during submaximal cycling. Journal of Applied Physiology 93:823-828.

comment Cyclocross bike as fast as a roadbike?
@DanielRHicks - You are likely over inflating your tires. 100 psi for 700x35c would be optimal for loads well over over 150 lbs per wheel! See bikequarterly.com/images/TireDrop.pdf - This could make your ride excessively harsh.

comment Cyclocross bike as fast as a roadbike?
@Trengot - The larger volume means you can run a lower pressure and get the same contact patch size. Larger volume tires need less pressure. Lower pressure also means more suspension, which can be faster on rougher roads. My 700x35 at 75 psi (15% sag) are much faster over B roads than 700 x23 at 110 psi. The difference is measurable and repeatable.
