Strength:

Stiff, Shifts Well, Relatively cheap, Spins true.

Weakness:

Heavy, says "tiagra" on it.

I purchased this crank to build up a Surly Crosscheck frame set on a budget, and after 2100 miles I can say it has done its job admirably. I paired the crank with an ultegra(6700) bottom bracket, shifters(6500), cassette, hubs and 105 derailluers(5600). Really only notice a slight difference in shifting performance and pedaling efficiency compared to my full 6700 (6750 crank) equipped Ti road bike. Hard to tell if the slight flex I feel is in the crank or the frame. Either way, at 1/3rd the price of an Ultegra 6750 you get 95% of the performance and a little more weight.

The only bad thing I notice is that the inside of the large chainring seems to be getting gouged up buy the chain when shifting in the front under high loads. And it the only component of my bike that says "Tiagra" lol.

Anyways, great for the money, highly recommended for commuter and cross applications, or where weight is not a big
concern. Certainly and upgrade over anything with an ISIS or square tapper BB, no more creaking. When the BB wares out it is a snap to change, Dura-Ace(7800/7900) ones are compatible and can be found for 35 ish $.

Hope this helps, happy spinning!

Strength:

Good looks, stiff, inexpensive, compact 50-34 ring setup

Weakness:

Heavier than some. But the big problem is large chainring is very noisy at moderate cadence (above 65 rpms). A new chain made no difference. It is as if the teeth are not milled properly.

Previous posters sum things up well, except the large chainring on mine is very noisy where ii interfaces with the chain.

Strength:

Much better shifting than triple -- which is obvious, but it really is great when you've worked with 3 rings for awhile. Inexpensive way to convert triple -> double. 34/27 combo is almost, but not quite as low as 30/25, and is enough for the steepest hills you can find.

Weakness:

Difficult to eliminate FD rub on the biggest ring in all the gears. I don't have any rub in any of the gears on the small ring. Chainline on my setup is probably not ideal.

Original bike build had a 30/42/52 triple and 12/25 9spd cassette. There are few compact double options in 9spd, so this was best option. Went with 34/50 chainrings and 12/27 cassette. Shifting is dramatically improved (I also swapped the triple FD with the tiagra FD) and I love the new setup. These cranks, while budget-level are still stiffer than the old ones on the original. Great conversion for < $200 for anyone tired of shifting a triple.

Strength:

Looks great, easy install. Just says Shimano, so it makes it easy to use with any group.

Weakness:

Little heaver, but so what, i'm 205-210lbs, so fewer mcdonalds runs will more than compensate.

Well i have to say that i was pleasently surprised when i took these out of the box. This Tiagra is designed with 9 speed in mind so it is a nice upgrade to older 9 speed systems. As a larger rider i am getting this for a few reasons. One was that no matter what i did, i could not get my octalink cranks to stop creaking. So i am hoping that this system should stop that. After that i wanted to give the compact crankset a try so i can pass on my observations to my customers.

Once i get a couple of rides in i will update this post. I look forward to testing this since i am a value/performance minded person.
