    Lennard Zinn has a report from someone trying to get an XTR Di2 rear derailleur to work on an otherwise Ultegra Di2 6870 system. Basically, the XTR RD doesn't function in this setup (and the same...

    I would go with two of the climbing shifters mounted to the top/flat section of the bar, model R600 (not the 7970 mentioned in a previous post, which are only compatible with the older Di2 10-speed...

    We tried a Rohloff on the tandem for several rides a couple of years ago (about 500 km). It didn't shift anywhere near as well when under load as a derailleur system does. We like to have our cranks...

    Thanks Dean, I really like your idea.

    I've been so focused on modifying freehub bodies on other wheels to make them work with 11 speed cassettes that I hadn't really considered modifying the...
  5. Options for 11-speed cassettes on tandems - hubs and cassettes

    It would be nice to upgrade the transmission on our tandem with an 11-speed cassette, possibly even Di2 like I have on my single bike that I really like. The problem is finding a 145mm tandem rear...

    I use a Planet Bike Superflash USB (sold under the brand-name "Smart" in Europe) with an additional rack bracket.

    I've never not been able to unscrew a GXP crank bolt with a long 8mm allen key. If it's really stuck, then I'd extend the tool with an old seatpost instead of a pair of pliers. If that still doesn't...

    It sounds like you might prefer the Trans Am Bike Race. It's unsupported and a bit longer than the RAAM route.

    I mentioned in my previous post that total weight was over 200 kg on that tour: 140kg for two riders (with shoes and clothes), 20kg for the tandem (with all accessories mounted), and up to 40kg for...

    We don't own any "go fast", light, fancy tandem wheels, only touring/all-purpose models (tandem wheels are not a good place to look for weight savings IMO). The rear rim was a Mavic A719 40-hole...

    I wouldn't start looking into new wheels until you've tried putting the largest tires that will fit with your current setup and going out and riding some unpaved roads. They'll probably perform...

    If 4 pannier bags is not enough storage room, then one option is to add custom frame bags. We had ours made by Porcelain Rocket:

    Any bike will be a problem on most high-speed inter-city trains in Italy, but if it is a standard regional train then normally bikes are fine, and you should be able to find somewhere to squeeze a...

    The Tubus Airy is great if you're putting side pannier bags on it, but it's far too narrow to mount a rack-top bag, which was probably what you were using on your seatpost mounted rack. I really like...

    I'm a pro bike mechanic in an upper-end bike shop. The only real issues that I've seen on any Di2 systems were on the first-generation Dura Ace Di2 7970. The current 11-speed groups (9070 and 6870)...

    A lot of road discs available right now are mechanical, not hydraulic. With mechanical discs and road levers, you notice pad wear quite quickly, much more so than on rim brakes I find. To avoid the...

    I think that the reason why Klean Kanteen doesn't make a version that fits the bottle cage bosses is that such bosses are not designed to take that much weight. Putting more weight on the bosses than...

    Solution: New brakes! But if your levers are also 7800 series then don't use the newer Shimano brakes (7900, 9000, or similar) because they are designed for a different brake pull ratio. Another...
