Shimano Tiagra crank worth it?

Notices
Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

Shimano Tiagra crank worth it?

Hey guys, so I have a '04 Felt F80. After reading around the web and looking over reviews I found that peoples main complaints were the crank isn't great and the wheelset is heavy. My current upgrades includge; Shimano 105 RD & FD, Velocity Spartucus 700 wheel set, and a different saddle.

The last thing I wanted to change at the moment was the crankset. My current crank is the stock FSA RPM Alloy, 30/42/52 tooth set-up, think it says "Power Pro" on the back of the arms. Anyways I have been looking around for a 9-speed 105 triple but since I'm new to the sport I'm not sure if I want to invest that much right now.

I recently found a 9-speed triple Tiagra with BB included for $45, very minimal use. Whether it weighs a few grams less or not I could honestly care less. In your opinion is this better or worse than what I have? And if so is it a good deal?

If the FSA crank you have isn't causing you problems, I'd just stick with it. Don't just put stock in what other people say. If you were happy with the crankset leave it.

Ride it into the ground and save up a little $ in the meantime.

Why are you wanting to stay with a triple? When you're getting into 9 and 10 speeds, a double is plenty for the work you're going to be doing. In doing a couple builds, I've found that Amazon.com is actually an amazing tool to use for parts because they care some older stock from different bike shops around, basically whoever wants to list their stuff. FSA makes a great crank actually, definitely comparable to 105 as far as im concerned. Do yourself a favor and look into getting a double. You'll save money and weight at the same time!

Well the only think with going to a double or a 10 speed is I didnt wanna switch out my FD and/or cassette along with my crank. The bike came as a triple and I just havent been inclined to change it.

You wouldn't need to change the front derailleur.... you would just lock out it's lowest position by adjusting the low limit screw.

But really, it sounds like you don't need to change the thing anyway if your one and only reason is what other people say about it on the interweb.

So true. My .02 about the double was if you had to change things, but as said, if you just want to change because of what you read, then dont. There are many other things to save up for!

Btw, is it just me or does it seem that Sora has a better rap than Tiagra? I just feel like people know that Sora is "low-end" but mixed reviews where-as Tiagra is generally just not talked about or at least not in much of a positive manner.

I actually just picked the bike up recently and am trying to get it set up for frequent usage, I plan on using it mostly for fitness purposes and I have been looking for something that has been reviewed well and performs well.

+ I didnt wanna pass up a deal haha.

For 'fitness' riding, the stock crank is adequate. Good deal or otherwise (and I would call yours an OK deal; not great, not terribly bad either), upgrading things for no practical purpose is just an unnecessary expense. If you want something for Bling's sake, save your money for something like a used 105 or SRAM Force crank.

Not that I wanna talk you out of spending your money on something that you want.... but you did ask for opinions on the matter.

Those FSA cranks are pretty crappy. My girlfriend has Sora on her bike, with those cranks on the bike. The rear shifting is pretty good, but the front shifting is horrid. IMO ditching that crappy crank for a quality crank is a great upgrade. I used to be skeptical, but ditching a square taper crank for an extrnal BB crank is one of the best upgrades I have made on a bike.
If you use your triple FD with a compact its a pretty cheap upgrade too. These are both good choices, depending on if you want a compact or a triple:

On closer look, this Sora crank is a really good deal too:

Tiagra stuff is so underrated it's not even funny. I just swapped out my whole Tiagra group for ultegra 6700 driveline (RD, cassette, chain) and 105 5700 FD and STIs and my buddy who bought the set says he much prefers the smooth shifting of the tiagra stuff. The tiagra group is by far the best for the money, these days anyways, for an entry level person. Plus, it looks like if the 105 group hooked up with the 6600 ultegra group and had offspring. Lol. I like the looks of the Tiagra group, and the STIs are pretty cheap these days. So, get the crankset, it's worth it. ........ Long winded answer, sorry. Lol

I had Tiagra on my CAAD9 for the first 4,000 miles or so, and it worked fine. I upgraded to a ten speed drivetrain because I got it at a good price - okay, and I just wanted to. I've saved my Tiagra parts and am looking for a frameset to use with them. I'd get the Tiagra as an upgrade.
