Good Prices on Omniums/Other Cranks?
Hey all. I've just snapped my chainring and crank arm and need to get them replaced ASAP.
I want something decent that won't break the bank and Omniums seem like a good way to go since they sell complete with chainring and BB. Does anyone know any good deals going on them at the moment? They need to ship to Australia too. I'm open to other suggestions if anyone knows of a good deal on any other cranks too. Any pointers much appreciated. |
Grr... I was just working out what gearing I'd want with some Omniums and the 48t chainring is a pain in the arse.
To get 70 gear inches I'd need an 18t cog which will only give me three skid patches. I could probably learn to live with 74 gear inches with a 17t cog though. |
I ride 48-17 and pretty much love it. Atlanta is pretty hilly, but I don't spin out and can still get up hills without mashing too hard. It's a good around town ratio all around. But my boyfriend just picked up the omniums and hasn't stopped raving about it, trying to persuade me to upgrade. He grabbed his on craigslist though, so that's no help to answering your question. Sorry.

can i ask how you snapped your chainring and crankarm?
geesh |
Have you tried Hillbrick Racing? I know they carry some Miche parts, but they may also have their own brand.
|
I bought the Omniums for my bike from ebay, cant remember the price but it was definitely cheaper than any track crankset sourced locally. I ride 48-18 around Melbourne but I don't skid, I don't think I could survive on 48-17 as I encounter a few hills on my journeys.

people need to stop overgearing!
|
But big gearing is hot.
|
so, did you just put too much torque on the components and they failed?
wow were you attempting the 1st ever fixed gear rail grind?:p |

Let people ride what gearing is correct for their terrain, riding style, strength, etc There is no correct gear ration, it can take a while to pinpoint what ratio you are most comfortable in most of the time. I push right below 80 on the street. Also to the OP, you can always change the chainring on the Omniums, if you buy them from your LBS they might even let you change the chainring size for no additional cost. (It would be worth it to email an online shop to see if they could do the same.) |
Yeah, how is between 70 and 80 gear inches too high for the streets? I feel this is a very recommendable area for urban riding.
|
46x17 for the win!

How do you figure 70 GI's high?

I ride 49:13 and I like it. For me, and perhaps this is personal, I think a 42t chainring is just tooooooo small. Even in Atlanta, as hilly as it is, I prefer a higher gearing so I can soar. Even so, I still spin out on some downhills.

It's 49:14, but yeah, I love it. I really really do. I easily go faster with this gear than any other ratio I run.
I guess it wasn't convenient for you to quote the part where I told the OP that my ratio was pretty extreme and that he would probably find 46:16 (which is about 76 GI if I recall) comfortable, or the part about how my other daily driver is geared at 46:15. Anyhow, just because I am sassy like that:

You probably want something like 46:16. Not too high, not too low. A lot of people I know find that ratio very comfortable. And you wouldn't need to get a new cog.

http://img222.imageshack.us/img222/3829/ohsnap.jpg I still haven't ordered anything... have to wait 'til next Tues when I'm paid now. I've been having a ******* time trying to find a place that has Omniums as well as a 17t cog in stock. Ordering from separate shops is a killer on postage over here, and my LBS's can take longer to get stuff in than if I order from the UK or the states. |
what kind of cranks are those?
|
dudezor---that looks rideable to me. Just superglue everything back together and give it a go!
|
I was thinking superglue, gaffer tape and zip ties.

Holy ****, you're a beast.

haha nah... I did think that chainring was a little light and flimsy when I put it on to change my gearing a few months back. Still, I didn't think I was powa-house enough to snap the thing. Also, during the autopsy I noticed that the bolt on the snapped spider arm was a little loose, which was probably a factor. I'll definitely be sticking to beefier chainrings after this effort anyway.
Lessons learnt: be more vigilant towards bike maintenance, and don't use weak-ass chainrings. |
