Personalizing my Rosetta


Front view



Side view



My Shimano Ultegra shifters jammed after 2 years of use. I found out the new ones would set me back by at least US$300, so I decided to look for alternatives. I saw a pretty good deal on EuroBikeParts - a pair of 2008 Campagnolo 10-speed shifters is only US$110! I had it for about a month now, and I'm very happy with it. I don't think I'll go back to Shimano's anymore.


I decided to tilt my stem upward like a mountain bike, so I can use the drops more often. Some purist might think it is unsightly, but I don't care as long as I feel comfortable and can generate more power. But this comes with a problem - I can't see the readout of my PowerTap computer if I mount it on the stem, and I hate putting things on the handlebar adjacent to the stem. I tried ViewPoint OS Spacebar and Minoura Swing Grip, but they loosen up very easily when hitting a bump. Finally, I found the Winwood Carbon Accessory Bar, which suits my need perfectly. I have the little guy mounted in the way that the PowerTap computer is in line with the stem, and the Garmin Etrex GPS device is slightly on the left side.


One thing I always feel uncomfortable on bike is the inability to see things in the back when I am hammering down a road. I could sit up and look behind, but then I'd have to slow down a bit. I found two products which solve my problem: the Sprintech Dropbar Mirror and the Italian Road Bike Mirror. I do have a complaint about the Sprintech one, though. The ball-and-socket design is too adjustable, and road bumps cause it to go out of alignment. So I cut a piece of foam and stuff it around around the joint to make it more stable. I think I'll give the Italian Road Bike Mirror a try next time.


One major problem of mating Campagnolo shifters with Shimano drivetrain is that the cable pull ratios are different on two systems. There are ways to get around this (please see this article), but I like the use of Jtek adapters the best. It is very easy to install - you just need to take the shift cable out from the rear derailer, trim the outer cable a little bit shorter, thread the shift cable into the adapter and then the rear derailer.


I always think that if a cheaper component works almost as good as the big-brand-name one, I'll take the cheaper one. Here's one example: the Microshift front derailer sold by Nashbar.


My Rosetta originally came with FSA Versa 53/39 crankset. I wanted to try compact cranksets to deal with the steep hills in Pittsburgh, and I thought I could save money by using the same model but with 50/34 chainrings. Because I could use the same bottom bracket, and swap out the compact crankset with the regular one when I need it. However, I noticed later that the square tapered bottom bracket is getting harder to get, and the size I need - 68/110 - is even rarer. I also don't use 53/39 crankset that often. So, I may switch to the newer one-piece crankset in the future.


Another example: the Nashbar F1 saddle. I like a saddle that comes with a center cutout, and the cutout has to extend all the way to where it supports the sit bones. Otherwise, it will feel like as if something is pinching my gentleman's luggage when riding.^_^


I wanted to get a power-measuring device ever since I read about how it could help me with my training. I originally planned to get a PowerTap after saving for a year, but when I saw CTS's advertisement about a 12-month payment plan for a PowerTap 2.4 SL, I couldn't resist.

Pre-ride 2009 Tour of the Tucker County Race course

Course name: Pre-ride 2009 Tour of the Tucker County Race



(Met a local saying that Lance Armstrong once did a race on this course - could it be the Kmart West Virginia Classic?)

Date and start time: 05/23/2009; 11:00 am

Location: Thomas, WV

Type/distance: Mostly rolling hills with a major climb at the end; 37 miles in total

Weather: 60-70 degF, a lot of shade on the course

Course condition: Mainly one-lane mountain roads. Lots of ruts and gravel. Quite a few corners are covered with gravel, especially on the right side of the road.

Race goal: Stay in the main group of cat 5 (if there is a separate field)

Race strategy: Stay near the front at the neutral part of the race - expect gaps forming at the long decent to the actual start of the race. Once the race starts, ride at my own tempo to save energy for the last climb. Save about 40% energy for the last climb. Ride slightly below threshold at the first 5 miles, and give it all in the next 0.8 miles. Take a break on the slight downhill after this, and ride hard again on the last 2.7 miles of climbing.

Pre-ride meal:
0530 - Pancakes with syrup (420 kcal); 1 glass of soy milk
1100 - 1 cliff bar, 20 oz of water with 4 scoops of Cytomax

Mid-ride meal :
12 Hammer gels (1080 kcal)
44 oz of water with 4 scoops of GU powder each

What I did well:
1. Using only gels for refueling seems to work

What I need to improve:
1. Leave for the race at 6:30 am instead

2. Carry two 24-oz water bottles - one filled with 2 scoops of sports drink and the other with 4 scoops.

3. Ride at slightly below threshold on the first 4.9 miles of climbing.

4. Do two laps of Sycamore St. (9.92 % for 0.5 miles) next Saturday to get used to climbing very steep hills

Aches/pains/problems afterwards:
1. Bottom bracket starts to creak - fixed

Note:
I woke up at 5 am, and picked up my friend at 7 am. We stopped at Morgantown for a short break, and arrived at Thomas, WV at 10:30 am.

Parking is very limited in Thomas, so are amenities. I wondered how they are going to deal with it on the race day? We started the ride at 11 am. On the descend to the actual race start, my friend and I both noticed how poor the road condition is - plenty of ruts and gravels. Also, the shade makes it hard to see clearly if wearing sunglasses.

The actual race start is in a small town called St. George. It starts out with a short steep climb, but transitions to rolling hills. The course took us back to St. George, and we took the same way back up to where we started the ride.

The ride back up is harder than we thought. Upon post-ride analyses, I noticed that it started with a 1.3% gradual climb for 4.9 miles, shoot up to a whooping 10.44% for 0.8 miles, fell down a little for a few yards, and went up again at 7% for 2.7 miles.

My refueling strategy seemed to work - I felt good throughout the ride. But the amount of water I carried - 44 oz - was barely enough. I think I'll need 48 oz instead.

Plenty of these open fields along the course

Anti-chain Drop Devices

Here are the two anti-chain drop devices I was talking about:
Deda Dog Fang Chain Keeper


Third Eye Chain Watcher



They only work with bikes with straight seat tubes, though. So, here’s another device that’s invented by Kristin Armstrong’s husband and coach:
K-Edge Chain Catcher
