I'm not a fan of Treks at all Thanks for posting the link to my site edsall78.

The mustache bars are great, I've never really felt a lacking in regards to drops on my 750.

But if you want an easy conversion to drops, I'd go friction bar end shifters and Tektro levers, which ever ones match the brake pull on your bike. It shouldn't be that hard, but you'll have to re-cable everything as well.

As stated before you'll need to swap stems as well, a dirt drop is best for the mustache, and your preference on the drop bar, I might suggest the technomic though.

Anyhow, it should be fun and I'm a huge proponent of anything bike project based
