Hi There - I am new to biking competitively and looking to do some half iron mans and eventually a full. I have located two bikes that I have ridden and like, one used and one new but want to get some real pro's opinions on which might be a better buy. Below is the outline of both of them and the first is less money by about $500. Any thoughts would be appreciated..


2014 Jamis Xenith Pro


Jamis' Xenith Pro is responsive, light, and ready to slay the hills and flatlands. The stiff, high-precision carbon frame incorporates asymmetrical chain stays for stiffness while Size Specific Tubing minimizes weight and optimizes pedaling efficiency in every size. A full carbon fork with tapered steered adds control to the front to give you dialed cornering precision. Used for 1 season in perfect mechanical condition. There are a few very minor scuffs. Mechanically perfect.
Frame size 58cm

Which one fits you better? This is the most important item to consider.

If you are truly new to biking, you really should go to a reputable bike shop and have them fit you properly. This will make all the difference in your enjoyment of the bike, your efficiency on the bike and avoidance of any repetitive use injuries going down the road.

They both fit quite well and are comfortable. Both 58cm and frames are similar although head tube on Diamondback is a bit larger. I plan on taking the used one to a shop to get a fit opinion as well before making a decision.

Thanks

I notice in your profile that you own a Cannondale Bad Boy. When you say you are new to biking, did you mean you are new to road biking?

Of the two, the Jamis is the better suited to competitive riding and racing.

The DB is an "endurance" category bike. These have a more upright, relaxed fit and more stable handling. They're great for longer rides and can usually take bigger tires for mixed surfaces but if you're racing, light and fast rules the day and even though it's older, the Jamis will do that better (assuming it fits well).

The jamis xenith is intended to be a race bike and would treat you well for fast riding. The downside would be that it's pretty much dedicated to road riding as it can only fit up to a 25mm tire, it will run at the chainstays and bigger (I have one). The diamondback can probably take a bigger tire because of the disc brakes and endurance bikes usually have a little more room in the frame for tires.

If you're going to do tri's, then the DiamondBack is not for you. Compact crank with 32T on back? Those rims are 21mm wide internally/25mm externally, they're made for wider tires. When you decide to upgrade with some nice aero road wheels, good luck finding 142mm road wheels w/ thru axles - they make them, but not aero. And disk brakes for ironmans? I'm sure the frame geometry is more relaxed, it'll be difficult to shift the body more forward over aero bars. Sounds like a nice bike, but not for triathlons.

If you're doing ironmans, then the DiamondBack is not for you. That is more of a 'gravel' bike. Although it has fairly aggressive geometry for endurance, it's still more relaxed than a tri bike, which will make it harder to get the forward positioning over aero bars. Compact crank with a 32T cassette? Disk brakes? And if you decide to upgrade to some aero wheels, good luck finding some w/ 142mm thru axles. They make them, but not aero. It sounds like a nice bike, but not if you're doing triathlons.

There are actually plenty of aero disc brake wheels with thru axles out there now. Here's a few:
