Subject: Re: [CR] Bigger frames


I am 6' 6" plus, very long in the leg, but also very light -- built like a streak of p**s as my rugby coach said when consigning my fledgeling career as a second-row forward to the scrapheap of history. I don't feel I can justify the cost of a custom-built frame -- largely because I'd feel such a prat if I didn't like it, and the chances of that seem a bit too high, given that I have no experience of commissioning bike frames and I guess few builders have much experience of building to my dimensions.

So, I end up on stock frames that come in at around the 25" mark and -- like my compatriot Mr Sayles -- ride around with my a**e in the air. The limiting factor is how high I can get the bars, which is obviously limited by steerer and stem, but also by the length of the top tube: if it is shortish to start with, my weight gets shifted backwards and I have to have an outlandishly long stem -- up to 120 mm is fine, 130mm can be OK, but 140 mm and I find I am riding badly.

For long rides I currently reach for a 64 x 61 cm frame with a 120 mm stem which I can ride all day in comfort. By the book, the frame is too small for me. Another I love to ride is even smaller, a 653 whippet of a frame, eager and demanding. Recently, I built up a huge Roy Thame frame with a 28" seat tube and an extra horizontal tube welded from the downtube to the seat tube about 5 inches above the BB to brace the main triangle. Steepish angles and not much rake to the fork. It is very well behaved, comnfortable and sure-footed, and ought to fit me pretty well, but after six months I don't really love it. In my mind, it's a plodder and on longer rides it is less comfortable than my smaller frames. Or maybe it is just less fun, not what I'm used to, and so on. I ended up putting flat bars on it and using it round town. I had another very large frame once, a Dave Lloyd cross bike with some of the scrappiest brazing I have ever seen, but it had the virtue for me of a monster top tube. It was comfortable to sit on and on the move was one of the best handling bikes I've ever ridden, but it was built of diamond section dedacciai zero uno tubing and even with 28c tyres it was horribly harsh.

So, winding eventually back to the original question, no, my bigger frames have been less, not more comfortable. All other things being equal, a longer tube will be more flexy than a shorter one -- but then too much flex can make a bike handle badly and that makes you tense up in the saddle, which is uncomfortable. All credit to you framebuilders who have to tease out these conundrums and build the answer in steel.

My comment would be that it is not primarily the flex of the frame but the position of one's body and the distribution of one's weight with relation to

the wheelbase that leads to comfort on the bike.

It may be that the rider/racer lessens his effort on a too-big sized bike, as compared to the same rider/racer's effort on a just-right sized bike. On the just-right bike, the rider/racer exerts to get the best out of him and the bike, which is the reason for the just-right bike. (And he has to really know how to handle his bike!) On any other bike outside of his just-right sized bike, he doesn't go all out, he doesn't put maximum demands on himself and the bike, he enjoys a ride of relaxation.

Delmas and list:

Years ago I worked at an architecture firm that was bidding to design the rehabilitation of Madison Square Garden. I remember that part of the work involved research into the history of M.S.G. including its origin as a velodrome and something else that was curious... and I'm not sure how true... elephant racing? The firm was (is?) huge, 3,500 people, and I had my hands full on a couple of other sports projects so I only heard bits and pieces. Speaking of bits and pieces, and of old velodromes, at a world championship about 3 or 4 years ago at the L.A. Velodrome (aka ADT Center Velodrome, Home Depot Velodrome) they had an exhibit of old Madison Square Garden photos and pieces of the original wood track.

Chuck Hoefer points out that positioning on the bike is much more important for comfort than any changes caused by a small difference in frame size.? ? True, but we're assuming identical position on the bike, either from increasing or decreasing seatpost setback and extension, and fitting a different reach stem.? With all those variables?neutralized, is there any anecdotal evidence that there's any perceivable difference in the ride of frames?at the upper and lower end of a rider's acceptable frame size range?? I seem to like my larger frames a touch more, or rather the frames that really have "it" for me seem to be the 64cm jobs as opposed to the 62cm ones.? And all my frames have, as far as I can measure, identical saddle to?BB position and pretty much?identical saddle to handlebar distance. ? ? We've had all sorts of responses from just the opposite (smaller frame handles better and so is "nicer"), mild agreement and some that say it's all in my head (which refutes all of you who claim I have nothing in the cabeza).? I certainly don't claim to have made any sort of rigorous test, which would require neutralizing innumerable variables, such as having identical frames with identical geometry and tubing but a 2cm difference in size, and then have the bikes ?built with identical components, especially?wheels, tires and saddles.? I'm not expecting any blinding insights, just trying to get a sense of whether other folks?have noticed anything similar (or exactly the opposite)?to what I've noticed.?

Hi Eric. Just two more bits of advise, and then I'll let ride the bike in peace. Before you bid on those ebay wheels, make sour that a Shimano cassette will fit on this hub. Different manufactures have different amounts of space between the gears, and if you don't use a Shimano cassette the indexed shifting will be really bad, if it works at all. Finally, the rear of the frame doesn't always have to make all the changes. If the axel is more than 140, I would call Bullseye and ask if a shorter axel can be installed. The Santa Rosa bike shops are pretty good, so you should be able to do this locally. Apologies to list members on the east cost, but the weather in CA for this weekend is forecasted to be in the mid 60s with little or no wind. A perfect weekend for a tandem ride.

Hey Tom, the updates seemed really hodge-podgey to me. not all bad, but not necessarily what i would've done. i'll keep the shifters, levers, derailleurs, but mis-matched wheels is a bicycle pet peeve of mine. as for wheels, the response i got from folks on the "spread" was quite varied from "no problem" to "i wouldn't advise it". so i take it as, if you find a wheelset, whatever the spacing from 126-135, then i'll be ok. so i did find some 40h Bullseye wheels with 27" Super Champions on ebay $200, that i'm considering getting. i'm waiting to hear back on the hub spacing incase it's too out of the ordinary. I did change out the stoker bar to an upright bar. it clears my legs, and makes it more comfortable for her. i also replaced the bars and keith anderson stem, with a shorter and less angled cinelli stem and nitto randonneur bars that have a shorter drop. thanks for your advice.

The brake levers are modern arrow type, as well as the Shimano deralleurs, and the bar end shifters. Since the back hub is an eight speed Hugi cassette than I would guess and all of these parts were added around the late 1990s. It appears that the bar end shifters were installed around this same time, so it should have indexed shifting. I can't see anyone buying new hub and deralleurs and then not buying new shifters.
>From what I have seen of Hugi hubs they are really good, and I would advise you to have it inspected to see if it can be saved. You should be able to install a 11-32 cassette on this hud, and this is also within the range of the rear deralleur. This just got easier. I was also thinking of the front wheel. If the two of you aren't going to go loaded touring with this bike, and your not heavier than average adults, than a standard 36 spoke 3x wheel will work just fine. As these are still pretty common it will save you allot of money from not having to buy an uncommon 40 spoke wheel. I do see 36 hole rims in 27" on ebay from time to time, so this can be done. My last bit of advice is to raise the stoker handlebar. I would guess that if you and your wife were to start doing on longer rides her back would get sour from being bent pretty far forward, and I have found we want to keep our better half happy. I hope these bits of advise help. Tom HarrimanSan Francisco, Ca

thanks for the reply. good call on the canti fit. the cantis on there now are adjustable, so they are working with 700c, but the don't work that well. i'll have to see how my pauls mount up. i know they aren't as adjustable, so that could be an issue. 27" wheels wouldn't be bad i guess. there are some nice tires and rims out there in that size. also the tandem is 140 spacing. so i'll hold off on a wheelset for now. if i'm lucky i'll find a set of Phils on CL for cheap. :) the wheelset will also determine cassette or freewheel. knowing i can go up to 8sp on the crankset makes it easy to find something with the gear ratio that will work for us. it currently has an 8sp on there now. i think the friction shifting deore derailleurs will work on any ratio, so i won't need to change those. here's a pic of what i'm starting with.<tandem1.jpg> the current set up stretches me out a bit. fortunately i have something i can replace the bar and stem with. i'm going to change them out for a shorter cinelli stem and nitto rando bars - hope the barends fit. i found some stoker bars today that i think might work too. they're bars that come on the commuter/townie Treks. basically alloy risers that look similar to the catalogue scan. we'll see how it goes. i think this will be a fun project. Thanks for the tips.Eric On Jan 24, 2011, at 9:26 PM, Tom Harriman wrote:Hi Eric. I few years back I belonged to a tandem club that often took blind people out for rides, so I did get some experience with this. I'll try to help out as best I can. I have found that SR post work well and last a long time, however if your having doubts about a thirty four year old part, than by all mean replace it. I do agree with you that modern brakes are a big improvement, and that you should install then. The one thing I would caution you about is that the cantilever monts are wielded to the frame and fork so that the brakes match up with a 27" rim. Going to the smaller 700c rim could cause you problems. If you have a 700c wheel set then put these in the frame and fork and see how the rim and brakes line up. I have know several people for whom this small distance was a big problem, so give this some thought before buying new parts. On old bikes you can match any kind of brake with any kind of brake lever. This will be simple. Eight speed chains will work with everything. As I recall stoker bars were the standard 31.0. I would take the old one to the shop with you, and have the employee match the two. This should be easy to resolve. I don't think you will have to replace the crank set, as long as the gear ratios work in your area, it should be fine. I also wanted to mention that I have a set of tandem wheels for sale. I was at a swap meet a while back and bought a pair of Mavic 40 hole rims and a pair of Shimano 40 hole hubs. The seller was planning on building these up, but never got to it. The rear hub is a seven speed freehub, and has a 145 spacing. You will need to measure the rear triangle to see if this will work. Let me know. This bike sounds like a fun project, let us know how it turns out. Tom HarrimanSan Francisco, Ca
