Gear Talk / Re: Bar End shifters vs
« on: July 15, 2012, 10:33:11 am »
I have bar end shifters on several bikes. I do not find them "twitchy". Very occasionally I alter the shifter position with my knee. I have removed brifters from my touring bike and the new touring bike I am modifying to replace it because of disadvantages discussed.

"Looking to buy the "tightest fit" tires is only going to make flat repairs more difficult, not provide any more security. "

No one said looking for tightest tires to buy. I would like to know which tires fit tightest. There is a difference.

As yet, arguing the question, but no answers.

As replied to another, I have experienced as others have posted online tires that not fit. 700c tires on 700c rims. Touring tire on touring rim. Modern hook rim.

I am not interested in arguing your experience. Your experience, vast as it might be, is minute, I'm sure, compared to all other bicyclists.

If you or others on list can provide answers to question, thanks; if not, then, for me, it was tried here, go on to other venues.

"A 700c tire on a  700c rim will fit and if properly inflated, should be acceptable".

Not true. I am not going to search for more examples for you to argue, but I have experienced as others have posted online tires that not fit.

If you can answer my question better than "Schwalbe and forget it", thanks; if not, I'm not going round and round with you.

"So, all tires fit all rims of the proper size." Not true, "fit" meaning hook in and stay. Examples:

Still interested in which touring tires fit tightest.

"The right bump" should not loosen the spokes, unless bump was so hard rim was flattened. Report of similar damage to similar Michelin tire:

My Seedhouse SL1 weighs less, and I can sit up in it.

"Why?"

Match tires with rims.

"Sorry, I've got to agree with Russ on this one.  Using www.sheldonbrown.com/gears and assuming a "standard" 11-34 cassette, and calculating the speed at 60 rpm (slower than I'd like to climb, but sometimes necessary), I fly up the hill at 3.4 mph using the 24 tooth chainring.  Compare that to crawling up the same hill with a 22.  (/sarcasm off)  Yes, you're talking about one extra gear.  But I'd give up that lower gear before I'd compromise shifting.  I don't know of a way to reliably shift to a 22 chainring using STI shifters, and it's critically important to be certain you can use that lowest gear when you hit the nasty hills.  Besides, we're approaching the speed at which I can walk a loaded touring bike uphill (2.7 mph, verified more times than I want to admit!)."

Compromising shifting is not true, with well planned gear ratios. As mentioned, I do not use or recommend STI shifters for touring (reason given). Walking a hill for me would be very rare (maybe you need lower gears). As I stated, I think 24T is fine for a target, but as I also stated, lower is better, particularly for someone with limited experience as the person who started this thread.  Percentage makes a difference, and it is not to palmed off with comment couple of teeth difference doesn't make a difference for lowest gear. I have experienced the difference using 24T low and 22T low over many thousands of miles.
That experience caused me to remove crank with 24T low on new bike I am building to substitute a crank with 22T low at significant expense.

"Low gearing:  Lower the better.  Smallest inner chainring possible.  Biggest rear cassette cog possible.  Your crankset seems to be 74mm bcd inner.  So 24 is the smallest.  Mountain bikes seem to use 22 teeth as the smallest.  Not much difference."

A difference that can make a difference. Not much difference in number of teeth, significant difference in percentage, 8 percent. Would you say dropping from 52 teeth to 48 teeth for large chainwheel is not much difference? Same 8 percent.

Gearing: I would keep 20 gear inches as target low for you. That is 24x32. Lower can be good. New bike I am currently building will have lower.

Front Derailleur: Probably over concern. I have used racing double derailleurs on triples with  range 53-24T with no problem. If derailleur has sufficient snuggle factor (my term), it will probably work. Snuggle factor: ability to get close enough to seat tube to drop onto small chainring of triple setup.

Shifters: I am taking brifters off my new touring bike and replacing them with bar ends. Too many stories of being unable to repair brifters on road.

Tires: I have toured on tires from 20 to 35mm. I suggest 32mm as target.

Spokes: Stick with 36 spokes. Much easier to get parts if need repairs on road, and should be adequate for your needs. What I use. Certainly 28mm tires and  40 or 48 spoke wheels is a mismatch.
