The 10-speed drivetrain on my Carbent has not shifted crisply in the rear since the bike was new. It was originally equipped with Dura Ace bar end shifters and Shimano Ultegra road bike front and rear derailleurs. Since I have had such good luck with the 10-speed SRAM Rival drivetrain on my Musashi, I replaced the right shifter with a SRAM TT-500 bar end, the rear derailleur with a SRAM Rival unit, and the Shimano cassette with a SRAM cassette. Still experienced some shifting problems. My latest attempt to improve the situation was to replace the bar end shifters with SRAM X.9 trigger shifters. In conjunction with the shifter change had to replace the Bacchetta long-reach handlebar with a RANS B-41 handlebar for leg clearance. The Ultegra road bike front derailleur was of course not compatible with the SRAM "Exact Shift" trigger shifter (The large lever on the shifter wouldn't even budge the derailler's lever arm). I solved that problem by fabricating a 15 mm extension for the lever arm. Shifts easily, now, and indexes properly. The rear derailleur upshifts fine, but downshifting against the spring pressure is not completely satisfactory, as I sometimes have to actuate the shifter lever again to center the chain on the cogs. My next step will be to replace the large diameter shifting cable with a smaller diameter one (Might be binding). If that doesn't work, may try a SRAM X.0 derailleur. A continuing saga. Oh well, at least I don't have bar ends poking me in the stomach when I make sharp turns.

...got three SRAM 971 chains (114 links each) for the Xstream...  each comes with its own quicklink, so to create the 270-link chain (the old chain measured 135", although the "official" RANS spec page says 134"), I only had to break apart one of them - which leaves enough behind so that I only have to buy two when I change out the chain on Terrie's StratusXP one of these days...   And let's just say there was a lot of counting of links to make sure I had it right...

Actually, I misspoke (mistyped)...  I should have said there were 270 (135") links on the old chain, although the RANS spec calls for 268 (134")...    

The Garmin Edge 305 arrived.  Sheesh!  It is microscopic!  It's no bigger than an old candybar phone, with a similarly small screen.  I am not so sure it will work well for ME, but Dave seems to be able to see/read the screen well enough.  But his eyes are better'n mine too.

Just for starters...Hostel Shoppe and Calhoun cycle.

As much as I hate the place, WalMart usually has that size for kids' bikes.

Got the Catrike chain tensioner in the mail yesterday and put it on the 700 while the SOTU was on  Wasn't too difficult, except for the three-handed part.  Also put on an alternate set of pedals, which Kathy can get into a little better.  We'll give it another test when the weather clears.
