I've spent about 100 miles on the Stella, maybe more and I can't seem to get comfortable with the Moustache Bars. Part of it is that the basket interferes with using the brake hoods for a hand position. The basket should be lower.
There are some other solutions. Ahearne makes a wonderful rack, as does Paul. I put out a question to the BOB list and the estimable Kent Peterson sent this. I'll have to check with Acme to see if they can do anything.
That aside, I'm having so much FUN riding this bike. I just seem to become one with the bike. I love riding it. It's been a tough week, three morning of getting up before 5 AM and getting out on the road but when you get off work and see Stella there waiting for you, it all seems worthwhile.
