Convert 2005 Marin Highway One hybrid

Apologies, bit of a long one this, but please bear with me!

I've weighing up the possibility of converting my Highway One to 'road spec', to include drop bars, brake lever/shifters etc...

The bike came with a fairly high spec form the factory:

Front derailleur: Shimano Tiagra
Rear derailleur: Shimano 105
Cassette: SRAM PG-950, Power Glide II, 9 speed 12-26
Crankset: FSA Carbon Pro Team Triple, 53/39/30
Brakes: Avid Single Digit with Shimano Power Modulator
Hubs: Shimano WH-R550

I'd like to retain as many of these parts as possible, so can anyone advise on the following:

* Should I/could I retain the Avid V brakes, or would I need to buy cantilevers?
* Would the derailleurs cope with the removal of the smaller ring at the front?
* Are there any brake levers/shifters that will be compatible with the exsiting kit?

thanks in advance

    why I'm answering this I don't know, as I'm very much not a fan of drops but...

    *Should I/could I retain the Avid V brakes, or would I need to buy cantilevers?
    Vs aren't compatible with road STIs, so no. You'd need cantis, mini Vs or a travel agent (but they're censored by all accounts)

    * Would the derailleurs cope with the removal of the smaller ring at the front?
    yes, basically. Do you intend to put a different chainset on or just remove the granny ring? If it's the former then a dedicated double front mech will be better. If it's the latter then it makes no sense unless you put a narrower BB on at the same time. Weight of a granny ring is eff all.


    *Are there any brake levers/shifters that will be compatible with the exsiting kit?
    To use drops you need STIs. Your mechs will be okay, your brakes not.

    Campag Mirage linear pull brakes (like v brakes) will work with STI shifters - £29.50 (Condor fit them to their Heritage tourer, brakes (and bike) got a great review in C+).

    You may find you need a shorter stem, if the frame was designed for flat bars the top tube may be long and with drops you may find the reach too far, just a maybe.

    As Maddog says, I don't think it is worth getting rid of the granny ring, it might weigh 100g ish - negligeable, and you may still use it on occasions.

    I am a fan of drops myself, but to be honest with the cost of doing this (£175 minimum I'd say, for 105 STI's, bars, bar tape, brakes, and maybe stem, more if you need a new BB) you might be better off just buying new (maybe selling the bike to part fund it). A fairly decent road bike like a Specialized Allez can be had for £500 (or less for an '07 model).
