Change gearing and brake set up questions.
Hello all!
I recently got a new bike, a 2016 Fuji cross 1.5 and i like it but there are two things that are seriously bugging me about it.
#1. The gearing, on the lowest gear, it just isn't working for me. I'm wondering what is the best way to go about changing it to make it more climb friendly. I have a road bike so I don't really care for high end gearing as I rarely get out of the small front ring when i'm off pavement anyway.
Currently it as a 46/36 front chainring with a 11-28t rear cassette.
#2 is the brakes, for a bike with disc brakes, they don't bite anywhere as good as I feel they should, and way under perform my road bikes rim brakes. I've already replaced the stock generic cables and hosing with some nice jagwire cables and housing, and its all adjusted well, but its still really poor. Ideally i'd like to be able to lock up the rear without much force. To lock up the rear right now I pretty much have to lean forward to unload the rear, and be in the drops to get the leverage to lock it up.
The stock brakes are TRP Spyre-C mechanical brakes w/ stock pads.
Where should I start, upgrading pads? replacing the caliper with something else?

Installing larger rear cog may require new RD or you check the exact model what it can handle. Alternatively smaller chainrings. Also may need FD replacement or at least verification.
On brakes, get hydraulic Deore for $50 each. Mechanical brakes have inherent limitations.

You can swap your 11-28 cassette for something with a larger big cog if your rear derailleur can handle the range. Your 105 derailleur's rated max cog is 32 teeth.
If you make both changes and go for a 34-tooth chainring and 11-32 cassette, your rear derailleur would need to handle a chain wrap of 33 teeth and your 105 derailleur can do that. The resulting change in gearing would bring your low gear down to 28.7 gear inches from 34.7, or about 17% lower.
