  1. It would be next to impossible to jump time from removing the tensioner. For this to happen, the chain would have to come off the sprocket and move a tooth. There is simply not enough room in there for this to happen. Unless of course you have VERY worn components, and if thats the case the tensioner won't help you anyway.
  2. Ironman sprockets do not break your hub, all this talk is ridiulous. It is maintenance issue weather you like it or not. If you notice Barry Hawk, Charlie Mullins and Shane Watts all run Ironman Sprockets with no problems. Every case of a "folded" sprocket can be traced back to the following factors: 1. failure of one or more sprocket bolts (came loose or broke) 2. Chain too tight 3. ovaled out hub holes from previous sprocket bolt failure. 4. cracked/weak hub which lets go and takes sprocket with it. I have been running Ironman Sprockets for 5 years with no problems at all. I do check my bolts before each race. I index a line from the nut to the hub, if the line no longer lines up, your nut is backing off. Very simple way to check.
  3. Not sure where you went for that response. Dirttricks.com makes Ironman sprockets. I know them well, and after talking to them about this thread, the above response did not come from Dirt Tricks. They have discontinued the 600 sprockets, which are the same as the 650L sprockets. They use a counter bored 10mm sprocket bolt, and not the regular 8mm counter sunk bolt. They said that by June they will start making them again due to people asking for them. ....FYI
  4. cheapest Ironman I have ever seen. http://qualitysmart.com
  5. I have a used front hub which is in really good shape. ( no dings or scratches). Send me a PM if your interested. Thanks.
  6. Thanks for reply and info!!
  7. Any help here would be great. I have discovered a decision letter from Jim Pena US Forest Service supervisior that he is shutting down all lands under his control on Dec 31st. This is some of the best riding that few know about, and there is well over 300miles of little known single track. I have attached a copy of his letter with contact info. I called and spoke with Fred Krueger to see if they would extend the mapping period. He said the 1000 miles of "new" trail is more than they can handle, so there will be nothing added. If they can't examine all of the 1000 miles by '08, whatever they don't get to will just be whiped off the map. ( the "appoved" map he is talking about includes only logging/fire roads) I have reviewed it. There is very little, if any, imput form our side. Decision Memo Temporary Order Restricting Motorized Wheeled Vehicles Plumas National Forest, 2006 I. Decision As Forest Supervisor of the Plumas National Forest, and in accordance to 36 CFR 261.56, I have decided to issue a Forest Order to prohibit cross-country motorized wheeled vehicle use. The Order prohibits the possession or use of a motorized wheeled vehicle off National Forest System roads, except for routes, open areas, and National Forest System trails shown on the maps in Exhibit A. For purposes of this order, a wheelchair is not considered to be a motorized wheeled vehicle. Pursuant to 36 CFR 261.50(e), the following persons are exempt from this order: 1. Any Federal, State, or local officer, or member of an organized rescue or fire fighting force in the performance of an official duty. 2. Persons with a permit from the Forest Service specifically authorizing the otherwise prohibited act or omission. This decision encompasses Plumas National Forest System lands. These lands are located in Plumas, Sierra, Lassen, Butte, and Yuba counties on the Beckwourth, Mt. Hough, and Feather River Ranger Districts in Townships 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, South, Ranges 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 East, Mount Diablo Base and Meridian. Copies of this Decision Memo, the Forest Order and maps are available at Plumas NF Supervisors Office in Quincy, Beckwourth Ranger Station in Blairsden, CA Mount Hough Ranger Station in Quincy, CA and Feather River Ranger Station in Oroville, Ca. This information is also available at local OHV shops, visitors bureaus etc. This will be in effect for one year beginning on December 31, 2006, and possibly could be extended, prior to a final system of routes, trails and areas being designated. The order will apply to National Forest System lands administered by the Plumas National Forest in Plumas, Lassen, Sierra, Yuba, and Butte Counties in California. In recent years, the number of recreationists using motorized wheeled vehicles to access the national forest has surged, leading to the proliferation of unplanned routes and associated resource damage. The purpose of this order is to prevent resource damage to wildlife, soils, plants, water and other resources caused by unregulated cross-country travel by motorized wheeled vehicles. This order is temporary. It is intended to stop resource damage and the creation of new routes while forest managers analyze the current motorized wheeled-vehicle roads, trails and areas and designate those open to motor vehicle use. In accordance with the National Environmental Policy Act Regulations at 40 CFR 1507.3((2)(ii), I have determined that Forest Service policy allows this action to be categorically excluded from the requirement to prepare an environmental assessment (EA) or an environmental impact statement (EIS). This action falls within Forest Service Handbook (FSH) Category 31.12 (1): Orders issued pursuant to 36 CFR Part 261- Prohibitions to provide short-term resource protection. I find that this order fits within this category of actions because it is short-term (approximately one year) and it is needed to protect resources. Therefore an EA or EIS is not required. Documentation and other records providing evidence of resource damage are located in the administrative record file at the Supervisors Office of the Plumas National Forest. Prior to taking this action, I consulted with an interdisciplinary team (IDT) to determine whether any extraordinary circumstances exist that would require preparation of an EA or EIS per FSH 1909.15, Chapter 30.3. IDT members included: Fred J. Krueger, Project Leader Will Gainok, Soil Scientist and Hydrologist George Garcia, Wildlife Biologist Joel Schultz, Wildlife Biologist Linnea Hanson, Botanist Kevin McCormick, Heritage Deborah Schoenberg, Recreation Based upon my review of this action and the administrative record, including consultation with the IDT and public involvement, I find no extraordinary circumstances related to the proposed action. Extraordinary circumstances include, but are not limited to, the presence of the following: Threatened or endangered species or sensitive species TES Flood plains, wetlands, or municipal watersheds Congressionally designated areas Inventoried Roadless Areas Research Natural Areas American Indians and Alaska Native religious or cultural sites Archeological sites or historic properties My decision is based on the following evidence that this action is needed now to prevent further resource damage: specialist reports on soil and hydrology, federally listed threatened and endangered species, Forest Service sensitive plants and animals, and heritage resources showing that damage has occurred to valuable resources in the past and that the action is needed to prevent damage in the future. In addition, I have examined the resource damage maps, photographs, and the background summaries describing the national, regional, and local situation. I have also reviewed the biological evaluations for threatened, endangered, and sensitive plant species, and terrestrial animal species. These documents and photographs are contained in the administrative record. Taking this action now will prevent violations of the National Historic Preservation Act, the Endangered Species Act, the Clean Water Act, and the Noxious Weed Act. II. Public Involvement. Public notification and scoping were conducted to help determine whether significant issues or extraordinary circumstances exist regarding the area closure. Public meetings were held in the fall of 2003 (3) and 2004 (4) to explain the process as well as keep the public involved in this process. During the summer of 2005 three field trips were also sponsored by the Plumas NF that explained the inventory to the public as well as demonstrated how the public could assist the Plumas with the route validation and evaluation process. The public also had the entire summer and fall of 2005 to identify any routes the National Forest possibly missed in its inventory. Notice of Plumas' proposal to restrict the use of OHV's to routes trails and areas appeared in local papers at the same time the public meetings and field trips were announced. The same information has also been posted on the Plumas' website. The Plumas NF has posted this action in the Forest's Schedule of Proposed Actions (SOPA) since September 2004. All press releases and external and internal meeting notices as well as written public comment received are available in the Supervisor's Office. No objections, substantive comments, or extraordinary circumstances were identified during scoping as potentially having effects, which may significantly affect the environment. III. Findings Required by Other Laws This area closure is consistent with the Plumas National Forest Land and Resource Management Plan, as amended by the Sierra Nevada Forest Plan Amendment. No laws, executive orders, or regulations would require a finding as shown in IDT reports. This action is in compliance with the provisions of the National Historic Preservation Act of 1966, as amended and codified in 36 CFR 800, and the Programmatic Agreement between the California State Historic Preservation Officer and the Forest Service regarding the treatment of historic properties by the National Forests of the Sierra Nevada. This action is also consistent with the requirements of the Endangered Species Act, the National Historic Preservation Act, the National Forest Management Act, Clean Water Act, and all other applicable acts. This action will not discriminate against any group or protected class because it applies to use of all wheeled motor vehicles. This process is open to the public and does not exclude anyone based on age, race, religion, sex, etc. IV. Implementation Date This decision will be implemented 30 days following publication of the Legal Notice in the Feather River Bulletin. ADMINISTRATIVE REVIEW OR APPEAL OPPORTUNITIES This decision is not subject to appeal pursuant to Forest Service Regulations at 36 CFR 215, Notice, Comment, and Appeal Procedures for National Forest System Projects and Activities, Section 215.12(f).

Krueger, at (530) 283-7840. Signed: /s/ James M. Pea, Forest Supervisor Date: Nov. 20, 2006 Published FRB, IVR, CP, PR Nov. 29, Dec. 6, 2006
  8. I have 3 years on my Ironman sprockets and I've desert raced all three years. I have about 4,000+ miles on these and the same Regina "z" ring chain. Awesome stuff!
  9. If you ride with your chain too tight it will overstress the sprocket bolts more than anything else. If your friend tacoed an Ironman sprocket, he lost a bolt, which worked on the next, then he lost 2 which = tacoed sprocket and generally a broken hub. You can check this by looking to see how many bolts you have left after destruction. If all pieces of the hub are still held onto the sprocket by a bolt, and all attached parts still have their bolts, I would then agree the sprocket failed. I guarentee that he re-used his sprocket bolts and did not red loc-tite them. I suspect nylon "nylock" lockers also which are junk after one use, mechanical locking ones are better, but, still use new one whenever possible. Most chains break around 7200-7800 lbs, Ironman sprockets break at about 8000-8500 lbs and your hub tabs break easily. Always a good idea for any sprocket replacement to use new bolts and red loc-tite.
  10. If you go to dirttricks.com you will find the mighty ironman sprockets. Riding on the street you will get at least 3 years on them.
  11. You can maximum life out of a Regina Z ring also. I run Ironman front and rear and have 2 years now on them of desert racing.
  12. Ironman sprockets are much stronger than any other on the market, and the fact they are warrantied for a year makes them the best choice period. Contact Nate@dirttricks.com and he will hook you up.
