The early Modolo sidepulls have some of the most flexible caliper arms out there. It's because of the very thin sectioned flat backed caliper arms that they had. Very pretty they were but also quite flawed because of the flex. They had some of the nicest looking levers though. Even the early Speedies had nice drillium levers with beautiful curves on the and high quality finish. Like noted, their sintered brake pads are not that great either, they're pretty harsh on anodized rims plus some had reported that they don't work as well as advertised in wet conditions.
