    Velo Orange Grand Cru Crankset

    Wondering if anyone has one and if so, how well it's been holding up.
    Mine arrived today and 'delicate' is about the only word I can use to describe it.
    Figured I'd ask and get riders/owners reviews.
    I don't hammer but I'm a wee bit concerned about those slender crank arms.

    Seriously? Those arms look beefier than Campy Nuovo Record cranks, which held up for tens of thousands of miles under the likes of Eddy Merckx. Are you a more manly man than Eddy?

    Never used them, but the look like typical SR or generic Taiwanese cranks of the type that's been OEM on millions of bikes over the last 5 decades. Unless they're of very unusually poor quality I wouldn't worry a bit.

    Very pretty. Copy of classic TA chainset which I note TA have stopped making. Cold forged 7075 with a high polish = high UTS with no stress raisers. Go and ride with confidence.

    The VO crank is patterned after the venerable TA Pro 5 vis, which was the crank of choice for tandems for many decades. If it can hold up to tandem use, it can probably hold up to you on a single as well.

    Those are classically styled, cold forged crank arms made using modern high strength alloys. If they look skinnier its because today hollow construction is common which makes arms lighter, not stronger. Those resemble the Shimano CX-400 and Shimano 600 crank arms I took off some bicycles last year. They were 19 and 24 years old respectively but still in perfect shape so those ones will probably last you a while.

    Delicate?? Those VO cranks look so beefy that it seems like they can be used in a tank's transmission. If you want to see what delicate looks like with a 1 piece Aluminum fluted style crank, check out Stonglight's model 106 at Velobase....Or Campagnolo's Super Record crank....
    Intrestingly, the Campy SR cranks were found to have cracking problems, but not because they were too delicate, but because they did not round off some critical corners where the crank arm and spider arms met, resulting in stress risers where cracking occured for some owners. I don't think the Stronglight 106 had the same problem though....

    Update: After a season of riding with the Grand Cru setup I thought I'd pass on my impressions and tips learned while setting up the derailleurs (specifically the front one)
    The issue of interaction between the front derailleur cage and the crank arm became apparent the first time I spun the crank.
    VO has sence upgraded the Grand Cru but for those who might be thinking of one: There's no standoff boss on the spider. (That curved out protrusion between the spider arms and where the BB fits in) Everything winds up REAL close.
    The VO suggested BB length of 122mm was dead..wrong. I played around with cassette spacers (7spd 8spd 9spd and 10spd ) and finally determined
    a 127mm with a 10spd cassette spaced would place the crankarm far enough outboard to allow The derailleur to shift onto the outer ring without hitting the arm and still allow me a decent use of gears in the rear.
    Regardless, one has to keep an eye on the distance as one runs thru the gears. The front cage needs to be tweaked in or out depending on where the chain line is a lot more than was ever necessary with my 50/34 traditional compact crank. One needs to lock in the stops on the FD.
    I was able to use my 8spd wheel without incident but have to tell everyone, the chainline deflection limits the number of cogs one can use before one has to switch up or down on the chainrings. I doubt a 9spd would work with this crankset.
    All that said: The crankset worked beautifully thruout the season. Rolling hill rides in central Pa, the two rides at the Cirque down in Leesburg, more than a few climbs in the southtowns of western new york and I was able to keep a 19mph pace with the club on the flats.
    I did have to tweak the rear derailleur so I could use a 30t. At 70 I needed that little bit of extra help on some of the hills.
    Would I do a super compact again?
    No..Hindsight being 20/20 the 50/34 coupled with a deore rear derailleur and a 9spd 11-32 setup would have allowed me a better setup and less changes on the front. A 46/34/24 triple would have done even better for the hills (and VO now offers just such a option although I'm uncertain I'd plunk down the $$$ for the grand cru. The Sugino knockoff at $129. does just as well)
    The crank drew favorable comments at the Cirque and thruout the riding season..
    It IS sturdy and the chain rings don't flex one iota .

    I've been using one for a couple years now, but the compact 50/34, 130mm BCD version.

    No issues like you describe, and I am familiar with that situation. Nothing but decent things to say about it. Don't know why, but it tended to drop the chain on the inside if I didn't have the inner f der cage rubbing on the chain a bit at big-small combo. So I got one of those shark-tooth chain keepers.

    Paired it with a 11-36 cassette out back for huge range.

    I know next to nothing. I am frequently wrong.
