comment Saddlebag Laptop advice
@andy256 - for giggles you should include a randomized response survey on an exam. My former supervisor estimated undergrad cheating at over 50%.

comment Saddlebag Laptop advice
@andy256 - As reformed PhD student (aka graduated) who carried their laptop on their bike everyday I humbly disagree. I backed up daily and never once lost data to a bike trip. I even toured between conferences (across Norway by dirt roads) with no problems. I think this is even less of an issue now with most laptops being solid state storage. Perhaps the grad student "lost data" is like the undergrad "dead grandparent" syndrome at exam time?

comment Can a sora 9 speed Rear Derailleur short cage support a 12-36 cassette single chain ring 56T?
Won't adding an extra long B screw also affect shifting in the lower gears? That said, like you suggest it could be worth giving it a shot before purchasing another derailleur.

You also need to consider the maximum supported cog size in addition to the total capacity.

comment I want to weld or braze the pedal to the crank arm, but what metals are they?
@whatsisname - All that was said in the answer was that the pedals will unthread in the event the pedals bearings jam. This statement is true and remains true. Never in the original answer did was it stated that this was the principle reason behind the design. While it may not be the principle reason for original design (as pointed out in the thread), it still none-the-less is an important feature of design that should be considered when welding the pedals in place. How is this for the "wrong reasons?"

comment Is a 29.5 km/h average speed decent for a 90 km ride (on road) with an elevation of 1200 m?
It is true ad hoc or unofficial rides can be challenging and dangerous. In the local one I used to frequent I would often make it my goal to shake out as many of the weaker riders as soon as early to keep it "safer" (if you could hold on you were likely experienced). When I ran organized club rides we always ensured everyone stuck together and new riders were guided as to the principles of pack riding.

@DanielRHicks - I brought up pedal unscrewing as this design feature would be lost with welding and it could result in injury if the pedal bearings bind. The OP may not be aware of this consequence.

comment Convenient bike-security measures for rural, small-town, and remote-touring environments
I locked my bikes even inside the house (mounted eyelets to concrete walls, locked to here). Room mates used to think I was paranoid until they lost all their bikes during a break-in. Vancouver BC has/had rampant bike theft.

comment Pain in the toes while cycling using clipless shoes
There is still debate about optimal shoe position, many are moving towards lining up the pedal axel to fall between the head of the 1st and 5th metatarsal bones. This seems to be especially important for longer feet (which may need more support). The 1st head is commonly referred to as the "ball of the foot."

comment Unbending Derailleur hanger
@ChrisinAK - removable hangers are usually aluminum which doesn't respond well to bending so replacement is the better way to go anyway. Typically steel frames do not use detachable hangers.

comment Unbending Derailleur hanger
@Batman - Because you should always reference the same spot on the wheel (i.e., rotate the wheel and measure at the valve stem) to keep your lateral position reference (i.e., side of the rim) at a constant position. This is why Park says to ensure the wheel is centred in the frame, if the wheel was not centred (e.g., axel at different position within the horizontal dropouts) then all bets are off.

comment Pressure mapping a Brooks saddle
@NeilFein a single pressure profile taken out of context is useless, but a series of profiles can be very informative even though a single profile is rider and position specific.
