I dfinately dOnt notice anything, I have them on my steve Bauer, and I don't notice any difference in pedal stroke hen the normal rings on my pinarello, do ppl onhere actually notice a difference? If so what's the difference?!
|
Not a fan of them, but a friend goes out of his way to find them. You should at least return them to the cycling stream...
|
I like them, but truthfully, I can't tell the difference. When possible, I like to keep the original components on the bike. I see no reason to change them out.
|
You should at least return them to the cycling stream... And, as for sharing, I have personally shared close to 600 bicycles in the past nine or ten years, and been part of an organization that has shared well over three thousand, in the past 4 1/2 years. I know I could do better, but then I would not have enough time to ride what I find and build. Does anyone know how I got the two stolen bikes? |
Randy, do you save scrap? The arms are worth throwing in a bucket for a few bucks at least. If only Thunder Bay wasn't so far we'd gladly take any aluminum cranks at our co-op, it's slim pickings in these parts and folks can use round rings on 'em.
I'm also in the "can't really tell a difference" camp. |
I know people who love biopace.
|
I like them.
Never EVER toss the steel 40T 130BCD ring....like hen's teeth and I guard my last one like a lion on a kill. Send me all you find. |

I have a Voyageur that has had the original Biopace triple crankset replaced for a regular old double (52/39?). Since I have chronic knee problems and would like a triple anyway, I'd like to try the Biopace on this bike.
If anyone has a triple they want to get rid of, let me know! -Lauren |
Seriously: If any of you have BioPace chainrings that you don't want, I would love a pair of 110 BCD chainrings in 36T and 46T. If they come attached to an alloy crank, that's even better! Will gladly pay shipping. Please send me a PM or email. Thanks.
|
You're joking, right? You're not actually throwing away functional, reasonable quality gear, right? I mean, around here, if it's not mountain bike crap it's rare as hell.
|
You can get decent money on eBay for the rings.
|
I can't tell the difference. I don't go out of my way to have or not have either round or oval-ish rings.
Surely you could move quite a few via eBay. If not, Don't you Canadiens recycle aluminum? |
I will take any Bio Pace rings you want toss in the trash can, I have a bunch of crank sets without rings and that would give me a chance to put them to good use. I have been searching for a lite bronze colored 52 or 53 tooth 130BCD chainring to use on my Centurion 600 crank, I picked up a 42 in the lite bronze and a 52 in a dark bronze ( looks brown) for it but the color difference is just to much to look good.

i think they are cool because they are a fad from the 80s but haven't ridden them enough to tell a difference. i've got 5 rings but none on any of my bikes right now.. one problem with biopace is for any given tooth count, you need more chainstay clearance on a BP ring vs a round ring.
|
I am in the love 'em camp. After a couple of years off from riding in the 80's I put a ton of miles on a Biopace bike and got to like them a lot, and they look kinda cool going around.
|
Anyone else tossing any of them Biopace and alike, please throw 'em in my bucket.
I'll pay shipping. |

Sheldon Brown said you could even use biopace rings with an IGH or single speed, but I did not find that to be the case. So I don't use them much, since I don't like derailleurs much. If anyone has a really big 110 BCD ring, like 62T or something, please let me know... that's what I need for my recumbent.

Wow, this thread. A hidden vein of high-pressure enthusiasm is breached, revealing deep and unknown passions.

There is a slight variation in tension resulting from the varying angle between the two straight runs of chain as the axis of the chainring rotates, but this has not generally been of a sufficient magnitude to cause any problem in practice for me.

Anyone seen a study to see if Bio-pace has real value performance wise? Does it really work?
Maybe its nothing more than psychological in that if you think it helps then it indeed does help. The entire world operates on such principals. |
Dunno, but several other non-round chainrings exist and have existed besides Biopace.
Current bits that you might see on bikes in the pro peloton go by the names O.Symetric and Rotor Q-rings. |

[QUOTE=ColonelJLloyd;12790769]That crazy cat used a Biopace ring on a fixed gear.
I found that a 42-tooth Biopace ring worked fine on a singlespeed I once had. No problems at all, and it did seem to make climbing a little easier But I later made it back into geared bike and gave it to my son. |

http://bikeforums.net/attachment.php...hmentid=206389 http://bikeforums.net/attachment.php...hmentid=206390 I'd like to see anybody spin that crank at 80rpm:-( http://www.flickr.com/photos/38236150@N06/5043540961 http://www.flickr.com/photos/38236150@N06/3919914081 |
