    Anyone ever ride a 69er?

    Along the path of attempting to convert my old steel 26 into a 700c, I have been riding the old bike with a road wheel from an old road bike in it up front, and a 85lb pressure slick on the old 26 inch rear. No front brake yet as I don't have an adapter yet. Will probably just order the xtracycle one.

    but, riding it around like this is not half bad really. I will get around to making or finding a wheel with an old MTB hub (my original is an '89 Deore XT-II 7 speed freewheel) to complete the conversion, but meanwhile, once I get the forward brake fixed up, this is not so bad. Touring around the Twin Falls canyon bike path with it's steep ups and downs revealed reasonable acceleration, and decent rolling. I finished off my rear pads though relying on them only. I have a new set, just had not gotten around to replacing them yet.

    Anyone else ride 69 style?

    This would be an easier conversion if you had disc brakes. I know you can use Paul's motolite for 650b conversion, but I don't think it has enough reach for 700c. I think this would be one goofy looking bike, but I'm curious about the tire clearance. How big a tire do you think you can squeeze in? Also, curious about wheel+tire dia compared to the 26 wheel+tire dia. How much is the BB raised? As long as you're having fun I imagine it's worth it, but what inspired you to do this?
    I don't know why,... it's just MUSS easier to pedal than the other ones.

    member digitalyon mentioned it in this thread:

    And I was further inspired in this thread:

    There is plenty of clearance in this frame, as you can see in the pics in the first thread I linked, at least for up to a reasonable commuter/cyclocross tire. Paul's motolites work fine, but are expensive. the xtracycle adapter is a relatively cheap fix.

    The bike currently has slicks on the 26 inch wheels. maybe the bottom bracket is raised a bit, but so far, it feels fine.

    Thanks. Some cool bikes there. Mine is a commuter, and given that there a quite a few who have converted old 26 inch bikes to 700c in this commuter world, just wondered if any left them as 69ers. It avoids some rear hub/wheel issues.

    26" conversion, to 29" (700c) capable

    Recently converted my '96 Schwinn Moab 3 MTB/hybrid hardtail
    from a 26" to a bike that can run 29/700c wheelsets
    (tires up to 40-42mm wide).

    The mod consisted of swapping 2 main areas:

    1. the 'steering column'
    (converted from stock SF threaded to rigid fork, threadless.
    This also included new stem, handlebar and headset as follows:

    Kona Project Two fork
    FSA DH Pro No. 15 headset
    Threadless stem (Profile Designs)
    31.x (?) handlebar

    2. The brake system,
    swapping from stock canti to special V-brake set with long arms (125mm) and 44mm of pad travel.
    This allows use of 26" brake bosses to reach 700c rims, with backward compatibility to 26" with a simple pad adjust.
    The long-arm V-brakes are available from a Taiwan seller on 'eBA'
    I paid $36.50 US with free S&H for the set to cover both wheels.
    Beats Paul BMX V-brakes at @ 100 USD per wheel !!!
    For the Taiwan 'longies' they have 4 metallic color options:
    black, blue, yellow, and red. Search for "extra long V brake"
    and you should find them. If you need the item# for the seller who's got them at 36.50/set + free S&H, let me know and I'll send in PM.

    With the brakes, I also swapped levers
    to Avid FR-5, and installed Jagwire cables.

    For all conversion parts/hardware (not including any wheelsets)
    I spent less than $200.

    Here's a few pics that show the profile/geo of the bike, pretty close to when it had the sloppy RST 171b SF, but more efficient to pedal now with the rigid fork. Of course it'a all a bit higher off the ground now with the larger diameter wheelset.
    The pics also show the V-brake set, which, along with the fork,
    can be 'retro-fit' with the original 26" wheelset as well.
    It currently has the 29/700 wheelset on it.
    PS the tires are CST E-Series Reach,
    in 700x40 (ERTO 622-42) unless I have that backwards lol.

    Looks great! I am still loving mine, though it is winter and it has not been out in a while.

    There is also a 700c conversion thread for pics of rides if you want to share there too.

    I think there is a general one somewhere that I cannot currently find. But here is mine. http://forums.mtbr.com/commuting/my-...-908426-2.html

    You might want to post in the "Pics of your commuter thread" here:
