|I am interested in the Jamis Eclipse frame which is a Reynolds 853 steel. I weigh 205 lbs. just wondering if that frame is suitable for my weight and any comments on the frame in general.

|I'm not sure about that frame, but 853 is great. Of the Reynolds steels, 853 is the current flagship. I have a mountain bike of 853 that is very forgiving and responsive. As far as strength, that steel would most certainly be suitable for your weight. It should last a lifetime, barring crashes and anything other than normal wear.|

Straight out of the Lemond crib sheet," The ultimate tensile strength of 853 is about 160% greater than standard aircraft grade 4130 cromoly. In fact, 853 has a strength:weight ratio equal to that of 3/2.5 titanium, but at a lower cost."

|I'm in the same boat as you weight-wise and am on a Steelman 853 frame. Plenty stiff for me and the ride is awesome compared to what I was riding (Cannondale). You should have no reservations about the frame material. The Jamis may use the "pro" 853 tubeset which is shaped (ovalised at the BB) for additional stiffness with no ride penalty. Looks like a great value, especially with the Mavic wheels.|

|I'm not sure, but I think that only the 3 main tubes are 853 on the Eclipse. Other frame builders use 853 throughout - Lemond, Waterford, Steelman (?), Strong (?). I'm sure the price of the Jamis is less, but the others are worth checking into. Also, Ritchey Road Logic is supposed to be really sweet.|

|Actually, most builders DON'T use 853 throughout. Until very very recently, 853 wasn't available for chain and seatstays, so most builders (IF, Waterford and most others) used the next closest thing---air-hardened True Temper OX platinum, which is nearly as good as 853 but not as expensive. Lately IF has gone to Columbus Foco in the rear, and a few builders are opting for full 853, though all it realistically does is jack up the price with no boost in weight savings or strength.|

|Lemond and a few others use 535 for seat and chainstays in lower end steel bikes. Still, it is a good setup.|

|525, Reynolds doesn't make 535.
Main diff 525 is CroMo (no heat treat) 531 is manganese molybdenum steel, 525 can be welded 531 better brazed and is mainly used for forks.

|the '01 zurich is 853 throughout||speeder|

|Also, it's not nearly as flexy as my litespeed MTB. I've never seen or heard any brake rub on my lemond. I've armed it w/ the superstiff sesteires though.
All in all, I'm very happy w/ my '01 zurich. With the ovalized down tube I notice no flex whatsoever.
The litespeed is collecting dust, but living in dallas will do that to any MTB'r
PS--I'm 215 (soon to be 185) :)

|The Lemond Zurich is priced lower than the Eclipse (but you get Ksyriums on the Eclipse).
Yes, 853 produces a great smooth ride. Regarding rider weight, though, I think it is indeed an issue and that 205 lbs may produce unwanted BB flex; many heavier riders here have either bought the Zurich and regretted it (where o where is Josh? remember him?) or test-ridden and forgetted (:-)) it. Concerning all that technical mumbo jumbo on bike sites about how strong 853 is, well, carbon is in some respects the strongest frame material used, but it still is considered fragile in practical terms by many.
|And I have heard...||Jim Burton|
Jul 17, 2001 9:17 AM
|that heavier riders also have dropped the rear wheel during hard sprints on the Zurich. However, this was on the 2000 models and was more of a funtion of the frame design rather that materials. That doesn't happen on other 853 bikes.|

|I also am building a bike. You may want to check out colombus tubes. The nivachrome is wonderful. Torelli has steel frames, the neuron and genius at under 4lbs for a great price. Chek with your LBS that carries the brand. Mate it with a carbon fork and you will have a sub 20lbs bike the will be stiff when you want to jam and smmoth on the long rides. Good luck.
