Is a spare tube going to be too bulky to pack in?I have one and have used it for about one full season. It doesn't move at all when riding. I went with this after using a Skyline pack. Much more minimal. The front pockets are great but can get a bit tight depending what you put in them. I do wish it had some kind of belt to secure the bottom part instead of just across the chest. I wind up tying the two straps that hang down a bit over my stomach. This season I decided to try going bladder-less so to speak and replaced this with a Bontrager hip pack. Now I carry a water bottle on my bike on one in my pack. If I feel I need more water for a ride I use my Chase. As much as I like the Chase over a bigger pack I really am getting used to having nothing on my back.
Depends on how much other stuff you carry. I could fit a spare tube, zip lock bag of first aid items, small multi tool, snack, money clip and phone but it was pushing it a bit. When the bladder is full it can make for feeling like you have a tumor on your upper back but obviously it is a bit more form fitting as you drink and the bladder gets smaller. I have since transitioned to carrying a tube, pump/multi tool (OneUp) on my bike and only the first aid, digital gauge, CO2, snack, keys, money clip and phone in my Bontrager fanny pack.Is a spare tube going to be too bulky to pack in?
There is room for the mentioned items. Also, the less water you fill the bladder with the less bulky it may feel.^^^ Is there enough room in the back pockets to store less frequently used items like a tube, mini pump/CO2, levers etc? The only things I'd really prefer to have in the front pockets would be my phone, small food items....
1.5 liters is equivalent to two large 24oz water bottles so plenty of H2O for most all of my rides. In many cases (cooler/shorter rides) I wouldn't have to fill it to capacity. I can put a bottle in the cage for additional water if needed.
I have a pixel 2 XL that I can fit into the front pocket (just barely, any bigger it would be tough. I have a slim case on mine as well. My outside to outside dimensions of my phone and case are 6-7/16" Tall x 3-1/4" Wide x 7/16" Tall.
I have an iPhone SE (5 size) and it fits easily. I was carrying in the unsecured, external pocket for awhile, but then I lost it riding bike park! Luckily someone turned it in. Super convenient to have it close at hand.
