Strength:

cheap, durable, trouble free, had it 3 years on 2 different bikes without any problems

Weakness:

nothing really

Got this crankset and BB with my first HT bike almost 4 years ago.

Since then I rode it 6000km of hard ascents and descents. I've jumped on it, ridden it hard. Hadn't made a creak. Changed pedals, never cleaned the BB (except one time when I moved it from my HT to my FS bike). BB still rotates like new.

If I was picky, I'd say that after 6000km of off road trips, the middle ring was a little warped (is it a good word ?) since I've hit it several times onto rocks and tree logs. But the biggest ring is in perfect condition :D (don't know how I did it).

It's the cheapest Truvativ crankset. Never really hoped it would last that long after such an abuse.

Strength:

None that I can think of, I suppose its inexpensive, it came stock on my $350 bike.

Weakness:

Chain ring mounting points are susceptible to bending.

I would not recommend this crank. I swapped my bent one out for middleburn rs-7s.

csmac2004   Cross Country Rider [May 19, 2010]
Strength:

Strong, good size

Weakness:

Tapered walls flared after two re-installs

Good crank for the money. Quick shifts, and easy to set up. After installing this, however, on my 2nd bike, the tapered walls have begun to flare out already. I have to use loc-tite on the bolts, or the crank works it's way off! However, for durability, these cranks are well worth the money.

Strength:

Solid, No issues to report.

Weakness:

Replaceable chainrings would be nice, but at this pricepoint it will never happen.

I am a clydesdale at 280 lbs. The only reason I had to replace them is because I bent the chainrings in a pretty bad crash. (7 months later and I still don't have a toe-nail on my left big toe!!). If they stood up to me, they will stand up to you.

TxHoss   Weekend Warrior [Apr 19, 2010]
Strength:

Held up to my 280lb Butt. No Issues have surfaced So Far.

Weakness:

It would be nice if the chainrings were replaceable, but at this price point, who cares.

This crank has held up to 2 years of trail and street riding with my big butt mashing on them. Finally bent them in a crash. If the middle chainring was replaceable I wouldn't even have had to replace them. I call that $40 worth!!

Similar Products Used: Lots of shimano's low end stuff, Sr suntour.

Jack   Cross Country Rider [Apr 16, 2010]
Strength:

Quiet, smooth shifting low-budget triple-ring crankset.

Weakness:

None so far

Does what it's supposed to do with no perceptible weaknesses. Nothing to look at but its a low-budget crankset. Good for entry-level set-ups or as an inexpensive replacement for a damaged crankset.
