Here at Pinkbike, we get inundated with all kinds of questions, ranging from the basic "Can I have stickers" to more in-depth, soul-searching types of queries like if you should pop the question or what to name your first child. Ask Pinkbike is an occasional column where we'll be hand-picking and answering questions that have been keeping readers up at night, although we'll likely steer clear of those last two and keep it more tech oriented.
PDXooo asks: I've noticed that when people ride with low tire pressures there's a noticeable amount of "tire sag". Won't such sagging cause a wheel to be\feel smaller than its actual size? In other words, isn't using lower tire pressures effectively reducing the overall diameter of a wheel? Honestly, I feel as if MTB riders are encouraged to use 29 wheels to counteract the loss in effective wheel diameter due to running the encouraged lower tire pressures!
I've noticed that when I sit on my bike, my tire profile at the contact patch is essentially flat - does this fact not make the profile of a tire, weather round due to a small inner rim width or flat\square due to a wide inner rim width......irrelevant?
Negative volume spacers for a light rider?Question:
Becka asks: I'm not using anywhere close to all the travel on the rear of my 2015 Canyon Spectral even with 35% sag and no volume spacers. If I run more than 35% the climbing becomes terrible. The rear feels too harsh and I'm getting bounced around on rough descents. I weigh 56kg and I have a RockShox Monarch shock with no volume spacers. I've heard that a damper re-valve could help but I will be buying a new bike soon so I don't want to pay out for a special super-light shock tune.
How to make frame bearings last longer?Question:
Adam asks via Instagram: My Whyte S-150 likes to eat pivot bearings and it's getting hungrier. Even with fancy bearings there's slack in the main pivot after a month or so. Your thoughts please?
