EEEEEKKK! My chain came off

[lph]

I LOVE that gear table

Now all you have to do is practice balance at low speed. Once you can ride really, really slow without falling over there's almost no limit to the hills you can tackle.

Great job, Pardes. Now, you can follow all of the advice you were given. I think we all thought you had a triple. Your geekiness has stood you well.

I think my minimum speed is 3mph!

you ARE nerdy. it took a lot of staring for me to partially comprehend your table.

Yes, I'm the poster child for newbie nerdiness. Generating a gear table in Excel has to rank at the top of the chart.

Thanks for all your replies. Now I'm wondering what can be my next nerdy project with the bike.....Hmmmmmm.

Bike maintenance?
Adding fenders, lights, reflective stuff to make you more visible?

On the Terry site, there is a short video called "Bicycle Gears" that explains the gearing, and the problems with cross-chain that will be very helpful for you as you learn the ins and outs of your triple.

My lowest speed has been 2.3mph, grinding my way up a very steep hill- feels dangerously close to falling over on one side, but I can do it.



Pardes- that is a VERY wide gear range you are getting! You will be able to handle any hill now ....except maybe those that require going backwards. I'm glad for you!...I know first hand how hard it can be to be a new rider in your 50's and trying to get up hills.
Great that your LBS is happy to change this for you on your new bike.

Keep in mind that when you have such a wide range there will be more undesireable gear combinations that will result in chain rubbing ("cross-chaining"). Cross chaining is to be avoided, as it results in both premature wear on the chain and cogs, and also increases the likelihood of your chain dropping off and/or jamming in the hub and chipping your spokes and paint. It might be VERY useful to have the LBS guys demonstrate to you about cross chaining with the bike up on a stand before you take it home.

One thing that helped me figure out my gearing was to think first about what front ring I wanted to be in for the riding situation at hand, and then think about fine tuning the back cogs within that front ring range. It also helped me to try to not be in either of the twoo extreme back gears on either side if I wanted to change rings in the front. This thinking is oversimplified and not always applicable, but it got me through the beginning stage of adapting to a big gear range with minimal chain drop and chain crossing problems.

Keep us posted- I love to read about your bike adventures!

Good comments about cross gearing, Lisa, but the gearing that I actually think she'll end up with is exactly the same as the majority of mountain bikes, 22-32-44 with an 11-34 cassette so it will get wider than the chart shows.

Unless there is some weird beast out there, cassettes are built on a spider with the largest gears permanently attached. They will not be swapping just the largest cog. The entire cassette will be replaced.

Fantastic! I was surprised they would sell you that bike with a double to begin with. Good for you to have gone there and requested the change.

I hope you will enjoy the new challenges allowed to you by the new gearing!
