help with bent wheel
Hi, the rear wheel on my Bianchi Milano has what I'm pretty sure is a bent rim. There's a wobble in it strong enough that I can feel it in my handlebars while riding. I think it may have been caused by riding on soft tires over potholes. Anyway, I'm familiar with truing to a certain extent, but this bike has internal hub breaks in the rear so there are no calipers to measure deflection. I'm not really up for buying a truing stand right now. Anyone have experience with this sort of set-up? I was thinking about getting some calipers and fixing them to the seat stays or something.
Thanks.
Thanks.

I use the clamp and the support of an old bike's bell. Mount it on one of the chainstay tubes and turn it close to the rim. Works easy.

Try a ty-wrap around one of the stay's with the end (you can cut off most of it) adjacent to the rim. You can move this around and use it as a pointer/caliper for rough trueing.

I take the tyre off and put masking tape across the frame then scrap a ruler across it to get the centre of the stays then measure then take the rim width from that... then half it....then mark the tape
IE stays 100mm apart rim 23mm 77mm so half is 38.5mm
should give lines on tape where rim should be I usually colour it with marker pen
get L shaped metal plate clamp them onto frame these can fine tune the wheel you move it in towards the wheel hear the scrapping noise true away from it

Two words: Zip tie.
Wrap zip ties around your seat stays. Cut them off at a convenient length for testing your rim's trueness. Cut them off of the bike when you're finished.

Relace the wheel,its not hard just take off the spokes and check if the rim is bent,if its bent too far than replace the rim and if you have extra money buy new spokes.Then just relace the wheel its not hard.When my trek cruiser started breaking spokes I learned in a hurry to wheel build and now its fine.
Just when you start to relace just screw the nipples until there are no treads visible,(thats your reference point)after the whole wheel is relaced just put it on the bike and turn each spoke at 1/2 to 1 turn intervals until they are snug and then slowly tighten then 1/4 turn until you get what you want as far as tightness is concerned.
After I relace my wheel the wheel is true but it still has a hump in it.(need a new rim)but I can deal with it(my tires have humps too).
I have no truing stand and no rim brakes(dont need them)I just used a pen on the frame to true the wheel.

If the rim is bent you are going to need more than a truing job.
The rim will need to be straightened or replaced. If you try to true a bent rim you'll have very uneven spoke tension and more problems.
