    Had a Surly Cross Check - was totaled in recent accident. Sadly now just a Fuji Crosstown as a backup bike.

    I'm getting a chance to spec a build, wanting to know if this would be stupid or good

    I'm starting with a 700c Long Haul trucker frame.

    I want to have a wheelset built around velocity touring rims (chuker I believe) 36 spoke.

    I want an IGH - for my budget the Shimano Alfine 8 or a Nexus 7 (I may lean toward the 7 for price)

    Here is the part I'm wondering - what shifter do you use with the hub? Can you use some sort of 'bar end' or 'friction' style shifter.

    Finally, on the front crank I'd like to run a compact double with a traditional front derailleur, so this would effectively give me 16 / 14 (depending on which hub I get) speeds, right? Would cross chaining be an issue? Also, are there issues with the Shimano Alfine on day to day commutes and pulling a slightly larger load (light touring / lots of loaded commute miles). I also live in a hilly area.

    So tell me if my idea is stupid. The reason I'd love this hub is that I have to start stop often. The shifting while stopped would be great. Also, I understand that once the cables have stopped stretching, these things don't need alot of fiddling (which would be NICE). However given my hilly area, I'd like a something like a 46 / 30 up front.

    Thanks for thoughts.

    You'll need a chain tensioner like this

    I have 24 traffic lights and 10 stop signs each direction on my commute. There's always enough warning to shift before stopping.

    On my derailleur equipped bike I only need to adjust cable tension when replacing the inner cables every few years and the one time my front derailleur clamp wasn't tight enough and it slipped.

    That's not really an improvement.

    I wish I had your experience with derailleurs. I was always having to fiddle with it to keep the indexing working. I ended up switching to friction shifters even though I preferred indexing just to save myself the grief.

    i've had a few years experience with a nexus 7 and found it to be a sound piece of equipment. i had a trigger shifter, and even though it worked flawlessly, was by all accounts one of the ugliest and cheapest looking things i've ever had on a bike since i was an adult. this was a while ago so things may have changed.

    as noted there is plenty of time to downshift before stopping with a derailer equiped drivetrain, and i lived in a city (sacramento) with no other transportation other than my bike, but still found the ability shift while stopped to be extremely convenient. YMMV.

    i'm a minimalist (some say simpleton...) so i wouldn't find the front derailer, cable, chain tensioner to be worth the bother, but many think otherwise... sounds workable though.

    BTW that nexus 7 weighs a ton, but suppose you know that already.

    There would be no "cross chaining" issue with a double, or even a triple, in front. You would not have the perfectly straight chainline IGH hubs are noted for in either chainring or just in the middle ring of a triple but the deviation won't be that much.
