I currently ride on Rubino Pro Slick tires, and have used various Vittoria tires for decades. The Vittoria Rubino tires you are using have similar wet grip to what I use (dry grip will be the same). The pressures you quote are good. I get the impression that both incidents occurred in the same corner. If that is the case then I would strongly suspect oil ...

These are referring to pad spacers. They essentially increase or decrease the amount of motion you have when moving the brake levers. See page 16 of the following PDF for a better diagram: Shimano Brake Levers User Guide

For grades beyond 10% having a gear that you can spin at the rate you can climb makes a big difference. Only you can know exactly what gear that should be. If you can find a gear ratio tool that displays speeds for a given gear, wheel size and rpm. This one seems pretty good. http://www.bikecalc.com/cadence_at_speed Then think about your typical speeds ...

Get the biggest. The down side is some bigger spacings. If money is an issue consider used. You have the option to not use a gear you do have. But you can't use a gear you don't have. Cassettes wear out. If you find yourself rarely using the 34 and/or 32 then get tighter for the next. Start with the biggest for a data point. If that is not ...

Personally, if your road frame is an out-and-out road bike - I would say you will be faced with several issues. strength of your frame Not only will this stress your frame - it may also fatigue the frame. And may cause sudden and catastrophic failure. tyre clearance Most road frames will not take a tyre greater than 28mm. Some no more than 25mm. ...

The two clicks are just one shift. You can do a half shift from the big ring to the small ring by pressing the downshift paddle about halfway. This is to keep the chain from rubbing when you are in a low gear in the back and the big gear in the front. This half shift is known as "trim". So two clicks up for a full shift into the big ring, two clicks down for ...

At your weight I would size up to 25mm tires and run lower pressures. High pressure does not corner better than lower pressure especially in wet. Lower pressure permits more of the tire to engage the pavement as contact patch as does a more supple casing. I weigh 150-160 and ride 700x23 racing clinchers at 75-90 psi. Also new tires can have a film on them. ...

Depends on the trails and the type of riding and how big of tires you can put on the road bike. Based on frame and brakes you are probably limited to 28mm or 30mm. Still a lot better than 25mm. If you are dealing with sand and/or big sharp rocks then 30mm is not enough. As for mud just don't ride mud. Mud need excess clearance. So you might as ...

You might be better off with one of the new bikes coming out with "gravel" or "all-road" geometry and clearance for ~40c tires. They're intended for the type of riding you describe. Current examples include the Raleigh Tamland and Willard, Salsa Warbird, All-City Space Horse, and Kona Rove. These bikes tend to have lower bottom brackets and longer ...

There are only really two things. First, as you identify, there is the issue of gradients. If you think that difference goes away if you just "man up", good luck with that. Even if you had the leg power (most of us don't, we'd end up pushing the bike and likely mashing our knees in the process), it would be very difficult to select one gearing that would be ...

I changed mine with 11-28 to 11-32. It makes a big difference. I can climb uphills quite easily now. Also I like the "Spin to Win" idea, and my new cassette makes me to spin more. I strongly recommend for 11-34 or 11-32.

It would be GREAT if you could try both, as several people mentioned here. Or if the shop can provide bike-fitting with an expert, that would be excellent. In general theory is not always right when it comes to bike sizing, you have to try by yourself. In all cases, here are some notes: Assuming that it doesn't differ with you which 'mode' you want to ...
