I have a set of Boscos on order at my LBS, but they're taking forever to arrive. I hadn't thought about a shorter stem, but based on all your descriptions, it absolutely makes sense that it might make a difference. You guys are the best! -- You received this message because you are subscribed

Cecily, My general rule when making changes is to change one thing at a time and see how that works, then isolate what still needs to be changed. Of course, I break that rule far too often, but it sure makes cause and effect easier to sort. So I'd start with the Boscos, see how they go, and

This is my Batavus: https://flic.kr/p/8RBm2N (may she rest in peace) The wheelbase is much longer than the Betty Foy, and the seat tube angle is more slack, so when I'm on it I'm in a sit up and beg position, similar to this: https://www.flickr.com/photos/mindcaster-ezzolicious/6476153325/

Cecily, thanks for the photos, that clarifies the differences very well ! It's obvious the Dutch bike has a much higher front-of-frame than the the Betty . And the seat and heat tube angles must be like 65 degrees or so. Having seen both, I can see why you're not comfortable on the Betty.

To clarify, not only the seat , but the bars can never back as far on a Betty than on the Dutch bike. The seat and head angles of the frame are just too different and the Betty was never meant to be Dutch-like . Make sense ? You know , don't try to make a banana and apple ;) -- You

Yes, it absolutely makes sense. I know you can't really compare the two styles, and as I said in another message, I don't want to be as upright as I was on the Dutch bike, because that position is really inefficient when you live in a city as hilly as Vancouver. But there were certain things

Garth nailed it pretty well. From this photo https://www.flickr.com/photos/cecily/9578404571 I would only add that it looks like you can put on a much shorter stem, and get some bars that don't go as far forward before looping back. That combo could get you more upright, but not as much as your

The Bosco bar with a short and high stem like this Soma http://www.yellowjersey.org/stemz.html would help, and I was going to suggest that , but then I saw the photos of the Dutch bike and I kinda doubted it would be close enough still. I think the thing to do is to measure the virtual

I'd go with shorter cranks, like a 152mm or less . I'm one to question every recommendation based on tradition or someone else's experience. Does this work for me ? That's all that matters. The shorter the crank, the less range of motion required to rotate the circle of spinning.

I am so sorry to hear that, Cecily! That's no fun at all. It would help to have a side photo of your current setup and if you know what stem and bars you have to share that. But an initial response is the Bosco bars come way back and very high, so if your stem is a 25.4 (and it is if you have

What length of crank are using Cecily ? The best combo I can think of to get your bars near and high-er is a Bosco bar and a short stem. Even higher can be had with a VO stem adapter and a threadless stem with a positive 10,20 or 35 degree angle. On Friday, May 16, 2014 5:07:43 PM

I am with Patrick, if you need really upright just get a super short 8cm tech delux stem and bosco bars, you can get the bars about 6 inches over the saddle that way. Now that might lead to a whole different host of issues for some people so YMMV. On Fri, May 16, 2014 at 5:14 PM, Deacon Patrick

This level of pain is probably best taken care by a sports therapist of some sort. Someone who specializes in bicycle related stuff. Anything we say is conjecture based on anecdotal experiences. Take your bike in and have them work with you. I would also recommend the Becoming a Supple Leopard
