I am keeping the drop bars. The multi positions are a life saver on long rides.
what crankset do you have now? whats the BCD (bolt center distance) ? if its like a standard 52-42 or whatever, you can get a 53 or 54 big ring for it. not much bigger or your derailleurs will run out of room.

the modern setup is to have an 11 tooth rear high gear (with 9-10 gears in back) and a "compact" 50-34 front. 50:11 is taller than 52:12 (4.545:1 vs 4.33:1) or 52:13 (4:1). 54:13 is 4.15:1 and 54:12 is 4.5:1


re: chain guards, the old school solution was a strap or clip to secure your pants leg cuffs. 'pant clips'...
the reflective velcro straps are, imho, better than the metal spring clips.

ah, thats more of a old style mountain setup. ok, then yeah, a new crankset. standard old school road double is 52-42, if you did this, you'd have no low gears. the compact double style would get you a 50 high gear and a 34 low, which is probably good enough. you might even be able to use your existing front derraileur, but you'll probably need a different shifter. I had a setup like that on my last street hybrid, but I used a friction shifter.

here's the seutp I was drooling on last night...








QBPDescPrice
CK4444Apex 170mm Black/Black 34-50 Crankset with Bottom Bracket$160.95
FD4681Apex 31.8mm Clamp Front Derailleur$63.95
RD5916Apex WiFli Rear Derailleur 10 speed Medium Cage Black$79.95
LD4671X.7 2 x 10 Trigger Shifter Set Gray$71.95
BR6754Avid FR-5 Single lever Right/Left Black/Black (qty 2)$19.90
FW6240SRAM PG-1050 10 speed 12-32 Cassette 12,13,14,15,17,19,22,25,28,32$79.95


those prices are basically list, I found at least $200 in savings online without too much trouble. the first column is the QBP part number.

oh, thats got trigger shifters and brake levers for flatbars, so you'd need a 2x10 brifter setup for your drop bars instead. sram apex makes a nice one. oh yeah, I forgot to add a sram 10 speed chain (you need a thinner chain to run this setup).


edit: wait, which Sugino crankset is it? are the chainrings seperate alloy rings, bolted to the crank spider, or are they all riveted together? If its the former, you need to figure out what the BCD is. see http://sheldonbrown.com/gloss_bo-z.html#bcd and measure carefully, you can probably get a 50 or 52 on there easily enough if its a 130 5-bolt, and your current derailleur can probably handle it with a bit of tweaking.

It has the bolt on chain rings.

I want a lighter more rigid setup though. When I peddle the arms visibly flex.

Also would be nice just to have 2 front chain rings as a more simple setup. I avoid cross chaining anyway so in actuality I already have similar total usable gears.

so you don't use that 28T small ring ? typical triple setup, you use the small ring with the 5-6 bigger rear sprockets, the middle ring with all of the rear, and the large front with the 5-6 smaller rear sprockets. with that sram 2x10 setup you can use pretty much all of the 10 rear gears with either the big 50 or small 34 front, although I'd still avoid the extreme crosses they say its usable.


if you are flexing sugino road arms, you're pedalling too hard, I've had Sugino triples and they were very stiff and rigid. more likely, you're flexing the frame, or maybe the bottom bracket (the axle between the cranks).

I always wear earplugs. Yes. You can still hear approaching cars.

Good job, on the mileage!

Pace yourself, on the way out. That way you have something left in the tank, for the way back in.

Also, when going for mileage, it's a good idea to ride a circular route around where you live. That way if you get fatigued or just aren't feeling it, you can easily get back home. Otherwise, you end up as much as 50 miles away and nobody wants to drive that far to pick you up. I usually try to stay within 25 miles of home.

Take advantage of the tailwind and loaf along. Yes. You turn a faster time by cranking it out, but, that does nothing for keeping something in the tank for the longhaul or headwind. I have the same high gear as you and have never tried to spin it out.

As for what you're wanting, SRAM and Shimano, both, offer options. You're basically looking at a compact crankset (50/34) with a wide-ratio cassette (11- or 12-32 or -36). You'll need to run at least a mid-cage rear derailluer (long-cage will work, too). Some lever sets will operate a double- or triple-crank front derailluer (not sure on yours). Both brands are designed to be cross-chained.

Like on Pierce's hybrid but for a compact crank.
Your better cranksets don't have chainguards with them. However, they are available. You may have to investigate the recumbent genre to find one, though.

Ducnut, that Sram Apex might be the ticket!

As far as pacing myself, I pretty much go for a higher limit naturally and have a difficult time slowing down. I do take frequent stops now that some of you folks say to drink every ten minutes or so.

With regards to going in the circular pattern, I am bored of riding in Las Vegas and have taken the show on the road. Wasn't cut off by a single car on the highway!

drinking every 10 minutes means sipping from your water bottle without stopping or hardly slowing down. the only stops would be to refill the bottle every hour or so.

Hydration pack? Which brings me to a question...how come I never see roadies using hydration packs? It's either water bottles in the jersey or on the frame. Aerodynamics or sommat?

weight on your back sucks when riding LD. blocks ventilation, etc.

I'll wear a Camelbak only when I'm on the cross bike out in the middle of nowhere, or on the MTB where I may be out for hours without easy access to civilization. Otherwise, I stick with bottles in cages due to their ease of use, lightweight, simple and I've usually calculated my calories per bottle based on what type of workout I'm doing. No excessive weight to carry on my back that inhibits sweating or heat buildup. I don't need all the extra storage of a pack on the road bike and it's just an understood breach of roadie etiquette to wear a Camelbak in a rotating paceline...

I have not invested in bottle cages or camel backs as of yet. I don't have a problem with the continuous pedaling. I just dislike the plastic water bottles. Maybe they have them in stainless and ultra thin/light?

That makes enough sense. I still use an older style Camelbak which does keep my back nice & warm. I run out of my 100 oz bladder in just over 2 hours on a warmer day...gonna consider adding cages next Summer as I ran out a few times this year. I'd never get anywhere using just bottles

I put an inexpensive stainless cage on my wife's comfort bike like this...



that nicely holds one of these thermos bottles...


those bottles have a pushbutton popup drinking spout that has a straw inside so you don't have to tip them up. downside, they are only 600ml or smoething, so you go through them pretty quickly. upside, they keep water cold for /hours/ and they are totally leakproof when being transported.

FWIW, the newer bicycle thin HDPE bottles don't have the nasty plastic stench of the old ones.

I tried using one of these,


but, when I dropped it when it was half full of water, it cracked :-/

these are nice, might be my next buy. I had one before but it got lost.
