That looks fantastic! It's a shame to see the chaincase go, but the Hollowtech cranks that continue the DA 7800 styling look really good with a single ring.

Not to mention that they eliminate yet another thing for a jean cuff to get caught on; I've found that square taper cranks alone aren't a guarantee you won't somehow get snagged on the crankarm's edge around the bolt mount (then again, 517's are my go-to, so it's not as if I make the situation any easier). This crank design basically makes snags impossible.

Incidentally, I found a similar dropout configuration on an el-cheapo, wannabe-motorcycle moped recently (also found a pair of very Q-factored cranks fitted with cotters - same size as a bicycle. Mad Honk's VAR tool made removal a breeze ).

I have been inspired by your thread to renovate a well-used Gazelle tourer "Superieur Special" with a design very similar to the Silver Ace, which I took over from a senior citizen in my neighborhood. Unlike you, I decided to put minimum money into the renovation which is quite close to stock condition.“Buying price” was six bottles of red wine, and I went for the bike because it was the more rare version (for Germany) with Sachs Super7 drum brake hub and matching front drum brake. I put back the stock 32 mm tires and modified the primary gearing to 38-21 which is the lower limit of the hub (compared to stock 46-19). Because my area is quite hilly, I wanted really low gears close to 1:1 ratio. I also cleaned and re-lubricated the gear hub which was otherwise in good condition. Braking power was poor initially although the pads were OK, after putting metal instead of plastic levers and low-compression Jagwire cable housings, it improved a lot and compares to 90ies rim brakes, I would say. This bike is now my runabout-town-bike for all seasons/all weathers. I am surprised the gap between the conservative “opafiets” look and the quite sporty handling… so different from the traditional Gazelle “Speciaal” tourer that I also own.
That's lovely to hear T700! Sounds like a good upgrade and maintenance to that bike. Any chance we might see more of it one day?

The SilverAce is still my commuter and run-about-town bicycle here though it might need a good clean when the weather makes for some warmer evenings.
In the meantime I just added a small modification to my Carradice Bagman support. The mini rack had some issues with the small bag and the heavy Abus Granit CityChain XPlus lock, or mostly the 2+kg (4.6lbs) lock had a tendency to make the bag sag.

So I tried adding some extra supports using some spare stainless steel spokes I removed in the past from a wheel build. It didn't go exacly as planned but here's what I tried:
  • Soldering them straight on.
    • Nope. Turns out soldering one steel thing to another big solid steel rod is hard with a soldering iron.
  • Soldering but adding some pilot holes
    • Didn't work either. I just couldn't heat up the bug supports enough.
  • Superglue
    • Nope
  • Drilling holes all the way through and just bending them around
    • Yeah that worked. Not my most gracious approach but highly funtional. 2mm stainless steel drill bit and a pair of lightweight 2mm spokes worked well.

Original. Sagilicious


Supports. Drilled and bent.
