Hi there. I called the local bike shop today because I want to get some work done on a Tange 5 cro-moly steel tubed 1985-ish Miele frame I have before I get it repainted. #1: I want to get the rear triangle spread from 126 mm to 130 mm. The bike shop says no will do as it puts too much stress on the welds etcetera and is very. In addition the cited liability issues because spreading the rear triangle is so dangerous. They will do a dropout allignment for $35 Canadian but strongly recommend me to *NOT* spread the rear triangle myself. #2: I want to chase or ream out the seat tube to its proper 27.2 mm size because the aluminium Aero seat post I want to put in is a very tight fit. I tried it on my other Miele and it fits fine so it is not the seat post that is too big. The bike shop said we won't do that we'll sell you a *NEW* seat post that fits for about $45 Canadian. The seat tube on this Miele is supposed to be 27.2 mm but the previous owner had a smaller seat post in it so now the top of the seat tube is not perfectly round which is why I wanted it chased or reamed. I already spread the slot back to its normal size but it appears that the top of the seat tube is not quite perfectly round. Or the seat tube may be slightly undersize as my 1985 Miele Equipe Pro (Dura Ace equipped) came with a 27.2 mm seat tube that had to be reamed slightly so the post could be inserted properly. So, does any one here know of a decent bike shop other than B****** in the Kitchener or Guelph area that can do this work? Thanks very much from Peter

I suppose there's a little change in the angle at which the dropout face contacts the hub locknut, but I don't think it's a lot. My guess is that the entire chainstay will bow slightly to allow the dropout face to contact the hub locknut squarely, with negligible deformation of all the metal involved. I've installed 130mm axles in two 126 mm frames so far, no ill effects yet with either one. No cold setting, no trips to the bike shop, just pull the dropouts a little further apart than usual each time I put the rear wheel in. mark

BFD! > > Yep, just put the wheel in the frame and go ride.- Hide quoted text - > > - Show quoted text - Hi there again. Riding theis bicycle with the 130 mm wheel was what I was doing until I read on this group that there was a risk of the rear dropout breaking which is why I decided to get the rear triangle cold set and the rear dropouts alligned professionally. Yes, this may have been an inexpensive frame but it has a very nice ride especially on long distances. Regarding seat post size; Sheldon Brown's page lists 27.2 mm as the seat post size for a Miele. It loks like this is another case of there being an exception to every rule. I will go to a shop close by and get them to measure the seat tube on this Tange 5 tube seat tube. Thanks again to every one who has helped. Cheers from Peter

Fact is, he probably *does not* need to have the frame spread from 126mm to 130m simply to accept a 130mm o/ l/d rear wheel. The bike shop was recommending the right course of action, but (possibly) for the wrong reasons. Also, a frame made of Tange 5 tubing and with a 28.6mm seat tube *will not* take a 27.2 mm seat post. Sounds like this was an inexpensive used frame, throwing $$$ at it seems pointless.

For a 4mm spread job why don't you just use the threaded rod, nuts and large washers technique (hardware store stuff). Just spread it wider and wider and release, check it periodically until it stays at 130mm. IME it is unlikely anything is going to break with this process. There has to be somebody willing to do this work locally, perhaps do the yellow pages thing, look for bike shops, ask questions. I'm about a 100km down the road the other way and know of B****** by reputation, I'd try somewhere smaller. Marcus

TRY http://www.parktool.com/repair/byregion.asp?catid=12&imageField2.x=8&imageField2.y=9 i assume chrome moly is touchier than quality carbon steel. also the shop may know your fram is oem brittle... With carbon, adding USS washers/cycle axle spacers either side hub then riding then adding another set, gradually widens the frame to your specs without stress. does the new hub carry a spacer (s) on it left side? remove the extra widths or substitute a thinner spacer to narrow the new hub to the original or lesser new, frame specs

This frame is Tange 5 cro-moly tubing. I do not think it is double butted although I could be wrong. Is it very likely that the inside diameter of the Tange 5 seat tube is less that 27.2? If so do you know what size seat post it should take? Thanks again from Peter

You can do that without having the rear spacing changed. In fact, that's what Shimano suggested back in 1988 when they introduced 8sp and most frames were ~`26mm and built of steel. Those early Shimano 8sp wheels came with "rounded" locknuts to make this easier; you might be able to find these at a well stocked old Shimano dealer. > > #2: I want to chase or ream out the seat tube to its proper 27.2 mm > size because the aluminium Aero seat post I want to put in is a very > tight fit.

How much of a difference is there (IOW, what size does the shop say will fit)? Also, are you sure this Miele does, in fact, take a 27.2 post? If it is built of heavier guage tubing, it will take a thinner post, despite having the same 28.6mm outer dimension as your other Miele. > > So, does any one here know of a decent bike shop other than B****** in > the Kitchener or Guelph area that can do this work? > > Thanks very much from Peter

There were also a number of bikes from that era that were built with double-butted, instead of single-butted, seat tubes. Such bikes would also have smaller seat post diameters, because there would be a thicker, butted section at the top (which is not found in most frames, since the theory is that the inserted seatpost reinforces the frame against flex at that area). --Mike Jacoubowsky Chain Reaction Bicycles www.ChainReaction.com Redwood City & Los Altos, CA USA
