shellbear Posts: 476	Re: Lancaster Rally -- Sat April 14th, 9AM Reply #15 - Mar 8^th, 2012, 2:04pm Thanks for the tips, Bob! I ride the Northwest Hwy hill near WRL all the time, so I guess I'm ok. I would love to ride more but work and family time is getting in the way. I am doing other exercises when I can't ride though!

Ric, the left TT500 bar end shifter and Rival front derailleur on your bike are compatible with a triple crankset, so all you would need would be a crankset, new bottom bracket, and a new 10-speed, long-cage rear derailleur (Your 10-speed Rival mid-cage derailleur would probably work OK, if you didn't try to shift into the 32T cassette cog, when in the big ring on the crankset). Knowing your riding style, and the fact you're not a weight weenie, I think a 48/36/26 MTB crankset would work for you. Theoretical speed at a 90 cadence in the 48T ring and 11T rear cog would be 30.6 mph. Theoretical speed at a 90 cadence in the 26T ring and 32T rear cog would be 5.7 mph (Fast enough for you to stay upright on your Musashi). Here's a decent crankset w/external-bearing bottom bracket: http://www.amazon.com/gp/product/B003OWYF1G/ref=s9_simh_gw_p200_d0_g200_i1?pf_rd _m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=121CS7NX2HHESPS0FFC7&pf_rd_t=101&pf_rd_p=470938631&pf_rd_i=507846. It's designated as a 9-speed crankset, but would be compatible with a 10-speed chain. Here's a good 10-speed, long-cage rear derailleur: http://www.ebay.com/itm/NEW-SRAM-X7-GREY-CARBON-10-SPEED-LONG-CAGE-REAR-DERAILLE UR-NEW-IN-BOX-X-7-/390374371074?pt=Cycling_Parts_Accessories&hash=item5ae4202f02#ht_1720wt_1396. Crankset w/BB - $88.66. Derailleur - $64.49.

Quote from jayg on Mar 7^th, 2012, 8:18pm:

If the cassette is an 11/34, the gear-inch value will be 26.3 and if 11/36, will be 24.8.

If you installed a 165 mm triple crankset on your bike, the lower gear-inch value would be 23.2 for an 11/34 cassette and 21.9 for an 11/36. The lower the gear-inch value, the greater the climbing power.

Or, to put it in layman's terms -- a "24 gear inch" value means that with every pedal stroke of ONE of your legs, it moves you forward one foot (12 inches), and with every complete rotation of the crank (i.e., both legs), you move forward 24 inches. When hill climbing, it's a fine line between at what speed you are going up the hill (how many crank rotations moving you X feet forward each time) vs. keeping your balance... And the effort to go up a hill at a certain speed on a bike is essentially like the difference between walking up a hill and trying to jog up it.

And to slightly modify what Jay said, the lower the gear-inch value, the slower you can climb while still keeping a decent pedal RPM going -- it's not really climbing "power" as such, it's the ability to keep pedaling at slow speed (as long as you can balance!)...

No, it means that you have the equivalent of a penny-farthing with a 24" wheel connected to the pedals, you are confusing "gear-inches" with the European cycling term "development". When I was running the 11-34 cassette on my Stratus with the tiny triple, my low-low gear was 19" (rounded up to the nearest whole inch).

I ride my bike to ride my bike, and sometimes it takes me where I need to go.

Well, ain't that a kick in the head!!! Sho' nuff, I've had it wrong all these last 5-6 years!!!! D'OH!

http://en.wikipedia.org/wiki/Gear_inches

Thanks, Opus -- I stand (or recline) corrected!!!! Thus, the distance travelled (i.e., 'development') per single leg stroke with a 24-gear-inch is [(3.14159 x 24") / 2], or 37.75", and one full rotation of the cranks moves you 3.14159 X 24", or 75.5"... and a 20-gear-inch development is 62.8" for a full rotation -- so you don't climb as far per rotation, thus making it "easier"...

Oh, and the Lancaster Rally 63-mile and 42-mile routes are definitely not a piece of cake... but it's a VERY enjoyable ride, with good rest stops every 10 miles or so and good SAG support. There is one tough 8% grade hill that is 5 miles in, but it's short, and the "Sugar Ridge Road" section from Mile 15 to Mile 19 is definitely hilly, with one particularly tough climb that a LOT of people walk up -- but the bluebonnets along that stretch are so pretty, you don't mind it!!! After that, the hill climbing is minimal, except for a short section around the 45 mile point. It's NOTHING like riding Muenster or any East Texas ride where there's nothing BUT climbing and rollers...

However, the WIND will be your enemy, if it's from the north, because the last 20 miles are northbound... but last year we had a south wind, which made the first half tough, but the last half NIIIIIICE!!!! But we're on recumbents, who cares about headwinds??????

Don't let the climbing scare you -- just plan for a lengthy, but enjoyable ride, with the occasional challenging climb that will make you appreciate it!!!

The 23-mile route is pretty much just for newbies, or those who just go out for 5-10 miles whenever they ride, and has that one climb at Mile 5 -- but it's basically just riding to Ferris and back...

The Garmin showed 2,000 feet total climb on the 100k, it wasn't a bad ride although the south wind was a pain going west through Palmer. Here's my data from last year's ride

Now I have an idea what the route might be. It really does sound like a nice ride. I will have to see how I do next weekend on the 50mi Ataxia route to know if I want to try the Lancaster ride.

I'm not sure yet how much I trust the elevation tracking on the Garmin - I have done loop routes where up and down don't match (even close) http://connect.garmin.com/activity/78205532

Garmins do a decent job when the barometric pressure is steady, but when it starts changing very quickly, all bets are off. Here's an elevation graph from a day I was doing hill repeats on Gifco Hill.

I guess that is what explains why a 12 mile ride around my neighborhood starting and ending at my house showed I climbed 300 more feet than I descended. For reference my ride on the same course on Monday showed a variance of 7 ft. Tuesday's ride showed a variance of 24 ft. I'll have to pay attention to the weather next time I get numbers that are way off.

Is it the elevations correction button that you can set to either enabled or disabled? I played with that on one's where it was way off 300 feet but it still didn't fix it. Maybe they don't know the elevations in Rowlett?
