I'm brand new to the Rohloff Speedhub club as I just recieved mine yesterday. This is the first time I've gone through the manual in detail, and I'm tempted to lightly push a few of the limits. I'm wondering if I'll get into trouble...
Gear Ratio must be more than 38t/16t:
I can find good SS 36t chainrings, but 38t ones are harder to come by. I already have a Surly 36t chainring on order. The Speedhub comes with a 16t cog, and I'm wondering if I really need to get a 38t chainring instead, or if I must replace the cog with the 15t cog. Is anyone running with a 36t/16t combination without problems? I'm 180lbs (borderline clyde) if that matters. I'm also more of a grinder than a spinner, so I'll be putting some torque on the cranks.
Use Speedbone only if dropouts are machined into same piece as brake mounts:
I've seen pictures of Rainman's SIR9 that have brake mounts welded onto the seat stays, so I've seen at least one case where this is not followed. My Mary SS has a much longer weld on the seat stay to hold the brake mount than the SIR9, so I'm assuming this rule is safe to push. Is this common to bypass this rule?
Use Speedbone only if there is 6mm radius on metal around brake mounts:
I measured the brake mounts on my Mary SS, and they total 11mm in diameter. Using the rule, I should not use this unless the tab that sticks out for the brake mount has 12mm diameter of metal around the brake mount holes. Again, should I be worried?
Thanks in advance for any guidance!
