What's an "MRP chain guide"?
See:
http://cgi.ebay.com/ws/eBayISAPI.dll...MEBI:IT&ih=003 There's a "chain guide" being sold with the crank... I guess "MRP" is a brand? So, what does it do? (It guides the chain, Bozo!) Yeah, but why? What's it for? Jones |

Yeah, but why? What's it for? MRP is (or was) a manufacturer that made parts for retaining the chain on single-ring derailleur bikes. These were specifically intended for downhill MTB racing. The MRP chain "guide" consisted of a pair of thin plate rings that bolted on outboard of the singlke toothed chainring, along with a boomerang-shaped gizmo that mounted by being pinched between the BB cup and the BB shell. The ends of the boomerang carried two small rubber sheaves. The chain ran around the chainring and inside the grooved sheaves which were mounted close to the chainring's side plates, making it almost impossible for the chain to jump off the chainring. |

It should be worth a thousand words in explaining the rationale for such a thing: http://www.pinkbike.com/photo/1435505/ Chalo |

Yeah, but why? What's it for? other-than-road riders use them to both keep the chain in place on big jumps and as a bash guard. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |
