Just scored a decent deal on a 2016 Corsstrail Comp disc. So far I am loving it. Smooth ride, fast smooth gear changing. Just curious as to what I can do, or others have done, to make this bike lighter or better performing?

Looking to put some tweaks into it to make it fun, just want to hear what others have done or what suggestions you might have to make it even better than it is.

Best thing to improve ride and lower weight is a higher end wheel set.
If that's not in the budget right now, higher quality tires.

Thanks! Any suggestions on Tires or wheels? I would love a set of Carbon wheels but some of the prices I've seen , whoa!

It probably just needs to be broken in.

Ride it gently for around 100 miles or so the first week. After that, ride the hell out of it as often as you can. As the motor gets stronger your bikes performance will improve as well.

lol thanks for the advice. I just want to tweak some of the stock stuff, like maybe handlebars, seat etc. Looking to see what folks recommend if anything.

Seems like a great bike so far especially coming off of a 23 old Cannondale m2000 with an original Manitou. What a difference in ride position.

"Don't fix what ain't broke".
Bike parts are a lot more expensive piecemeal than when bought on a bike. Thorough upgrades is usually a poor way of managing your money.
A better option is to get a jar.
Write "new bike" on it.
And everytime you get the urge to replace fully functional parts, stuff money into the jar until the urge passes.
("bike trip" or "big tool set" are acceptable substitutes for "new bike")
Fit items are OK to replace. No point in avoidable suffering. And it's not like you can wear out a stem or a bar anytime soon.
I consider keeping two wheelsets OK - as long as you have reasonably dissimilar tires on them.
Personal recommendations are a so-so thing. At that price, it's a decent enough bike. Nothing that actually needs replacing. A change I'd prefer might not do anything for you. Ride it until you discover what - if anything - that isn't quite working for you.

Upgrading components before barely trying out the original ones means you'll never know if the expense was worth it. For example, the original tires on my bike gave me no confidence in corners and they wore out quickly. I changed to Continentals and immediately felt much, much more confident in corners, so it's easy to see that it was a smart "investment". Same with the wheels. I bought a 2013 Trek Madone 3.1, and pretty much every review mentioned it was a great bike that was let down by it's less than ideal wheelset. I rode it 2 years however before finally buying better wheels, and I can now see what they meant. If I'm being totally honest though, for my level of riding, the wheels were okay, but I wanted to customize my bike, so I got a better looking bike (to me) as well as better handling.

As mentioned though, ride it for a while and if anything, that will give you the order of priorities.

excellent advice, and appreciate the candor and I agree and will take the advice. Seat might be only thing I need to change but again I need some more time on it before I decide.
