changing triple to double(7 posts)

How hard is it to change a triple to a double? This is not a bash on triple chainrings... I used it quite a bit but now I'm finally strong enough where I don't think I need the lower gearing and desire the "sleeker" look of a double. I have a slightly older bike with an 8 speed in the back so I'm wondering if this would cause any headaches since most componetry these days seems to be designed for 9 speed... would I need new 8 speed shifters, deraliurs (sp) (looking around it seems that I'd need a new rear der if I'm making the switch in addition obviously to a new front der)? The only way I'd do this is if I can do it without buying new shifters. In an ideal world I'd just buy a new bike but I'm on a student budget. Thanks and feel free to try to talk me out of this minor investment for what is truly pure vain reasons!

Since you have a strict budget, my advice is to forget it. If you want a double, take the inner chainring off and adjust the low limit screw on the front derailleur to eliminate the lowest position.

Since you are a student on a tight budget, the best answer is just don't do it. Plus it just doesn't make sense to spend that much money on 8-speed components.
If money were not an issue I would say replace the shifters, crank-set, bottom bracket, both derailleurs, and chain to 9-speed.
It's just not worth the money to obtain a "sleeker look" as you put it. Save your money and buy a new bike when the time is right.

Yeah, don't bother. You may have an easier time selling it with the triple - something to think about. It can be just as much a selling point to someone else as a detraction ot you.
I'm with everybody else--if you MUST, pull the small ringretro

Makes no sense, especially on your budget (we've all been there). If you simply can't live with the small ring, take if off and turn the low limit screw in to keep the front d. from shifting into air.

Get yourself a singlespeed. It can be a bit of beater (old horizontal dropout frame w/ re-dished freewheel hub and BMX cog), so it need not cost much. You could probably scaveng the frame, scrounge some square taper cranks, maybe put in a new BB, buy a BMX freewheel and a new chain, and have one for $40.
This gives that sweet looking "messanger freak" look. When you are on a SS, everything else looks over-complex. Plus you'll have a zero maintenace bike for days when your gearie breaks down. AND it will definatley make you a stronger rider.
Just watch out- you may end up liking it so much, a double will seem excessive by the time you can afford it.
agree w/others but DON'T pull the small ring..._rt_

even if you adjust the limit screws on the front der to prevent shifting down to the small ring you will never be able to get the adjustment perfect and will run the risk of throwing your chain to the inside (at the most inopportune moment, of course) and subsequently getting it wrapped around the chain ring bolt mounts.....not that i would know anythign about this....really.....a, uh, friend told me about this problem.....yeah, friend. ;-P

leave the triple, save your money, graduate from school, get a great job, and then buy a new bike!
