Taking Comstars to bits --- Again.

<< < (5/7) > >>

K2-K6:
Just to add a bit to that already posted; The bit where the spokes have been bent is at the point I perceive to be the most stressed, so ANY compromise at this point is likely to raise the risk of failure signficantly.

The materials used including the bolts/nuts/rivets etc will have been specified with the full knowledge of the designing engineer, to substitute off the sheld items without that background information I would place as a high risk choice and one that you may not find out the shortfall of until it stops working.

Believe me, i would certainly re-use anything that I can and not be an advocate of just "new is better" but I consider the risks here just too great to take on without a very good knowledge of what you are doing.

If you get just one joint failure, the design of these wheels to me would seem to have a high chance of the rest following shortly after. They are a very strong reliable design in their original form but rebuilding without an appropriate level of skill is not something I'd like to ride around on.

Just imagine that failure happening while you were on a busy motorway and I think you'd consider it differently, the risk is not worth it.

UK Pete:
Just think you could do the repair to these wheels, and all goes well,and they seem perfect, you sell the bike at a later date and some poor unsuspecting person could have a nasty accident ,and possibly loose their life
These wheels usually only fetch about £20 second hand, so its well worth replacing with a good second hand one, rather than going to all that effort

Point Well made and understood will be looking out for a good secondhand F2 rear wheel comstar,the one i had was very rusty anyway and not usable so stripping it didnt cost me that much.
Would a cb900 early comstar fit does anyone know ?

Thanks again for all your advice im still going to look into a rear disc conversion but without stripping a wheel to do it
