    I use a cross bike for commuting in the winter or rain. The biggest advantage for me is the ability to put on full fenders vs the clip-ons I previously used on a road bike. The roads I ride on are...

    The amount of work required to get up a steep hill is the same regardless of what gear you're using. Higher gears require more power and will result in higher speed but the hill will be over sooner....

    I've always assumed my VO2Max power was roughly equivalent to the highest power I could put out for 5 min. In your case I suspect that would be considerably below 343W.

    Whether you actually reach...

    "road race training" is a broad term and could include sprints where you would have zero time in Z4 to threshold intervals where you should have 30+ min in Z4. It sounds like you went out on your own...

    This thread is 8 yrs old so I wouldn't expect a response. Most often the reason for a blown tube is incorrect installation. Put some air in it and go around the wheel squeezing the tire making sure...

    If you're training for something every ride's a training ride. They all have different requirements. If those zones are accurate and you were doing 2x20 intervals then I would say yes you need to...

    It's not the highest skill sport out there, nevertheless there is still a significant disadvantage to someone who starts racing at 25 vs 15.

    My trip is fairly long 33km so I don't usually extend it much. I sometimes take a different route by the river that adds a few km and if it's particularly miserable I can shorten it up by a couple of...

    Sure. But I don't understand your earlier statement that training using maxHR is somehow preferable to using LTHR. Or better, yet ignoring your HR altogether if you're just looking for a healthier...

    Cardiac 'strength' is seldom, if ever, a limiter of cycling performance. Your heart pumps as fast as it needs to. You don't slow down because your heart gets tired of pumping.

    On dry pavement car tires and bike tires generally work better when they're worn. For performance car tires you can actually pay extra to have them shaved so the tread size is reduced.

    Garmin 500 is the simplest and least expensive GPS. No maps but you can download courses and it will give you directions (i.e. when to turn).

    Garmin 800 if you want maps. Larger display allows you...

    Ritchey is not a tool maker. They make bikes and bike parts. No wrench is perfect and similar torque wrenches from quality tool manufacturers are in the 10% range.

    No idea what you're trying to say here but wind tunnels are not solely used for aircraft design. Certainly the auto industry spends a lot of time optimizing their designs for operation at 50mph and...

    What makes you think the Ritchey tool is any more accurate than the HF tool the OP suggested?

    When you think you're applying 5nm with your Ritchey it could be anywhere from 4.5 to 5.5 and more...

    It's not hard to accurately check the calibration of a torque wrench provided you have an accurate kitchen scale and a ruler. It's unlikely the Ritchey tools are any more than +/- 10% accurate in any...
