ROAD CHAINRINGS...RAMPED VS NOT RAMPED(7 posts)

ROAD CHAINRINGS...RAMPED VS NOT RAMPEDdaveo
Mar 12, 2003 3:37 PM
i was told sugino rings were the best value for the money...but have heard conflicting ideas on shiftramps...are they totaly necessary? Do i have to use shimano rings with a 9speed shimano set up? thanks dave
Ramped = goodKerry

Shifting without ramped chainrings is noticeably not as good. It may still be OK, but there is no question that the ramps and pins are helpful.
Shimano rings are the best!russw19

Shimano makes some things worlds better than the next best competitor. Chainrings are one of them. Outside of Biopace rings, have you ever heard one negative review of Shimano chainrings? Shimano rings are the crux by which all others are forced to measure up to.

Not a thing in regards to shifting performance!

If you want to shift while putting a lot of pressure on the pedals, you need ramped rings. Without the ramps, you need to ease up when shifting between the rings.

- but you may find that they help. Certainly, shifting under load is more positive, but this isn't much of an issue most of the time.

Most of my bikes have non-ramped rings and I don't really miss them often...

As for Shimano making the best rings(!) - what about TA, Stronglight, Campag, Chris Bell, Sugino, etc, etc...

Shimano are okay, but nothing special. One of the worst experiences I've had was with an XTR middle ring which (due to those *wonderful* ramps and cutouts) made more noise (on small cogs) and dropped the chain (on big cogs).

Caveat emptor!
