Six days to the ride. I am riding today. I have only ridden once this past week because of rain. At this point I just need to stay limber. I am having to wear cool weather gear. I do not like wearing the restrictive clothing. I guess it's not that restrictive, I just don't like wearing it. LOL Hopefully, I won't need my rain jacket for the upcoming ride. It will make riding noisy.

This is my kind of thread. I ride both MTB and road. I've raced a bunch of ultra endurance races here in CO and some of the bigger road bike rides like double-triple bypass.

My #1 bike is a 2013 Colnago Master 30th anniversary running Dura Ace 9000. It was my dream bike for years and I eventually was able to buy and build one. My wife also rides one of these, but a '99 in the white/blue AD paint. My main MTB is a 2010 Giant Trance SL0 running SRAM XX. I'm a bit odd but I like the 26" tire size and this bike still has lots of life in it. I have the Giant press tools to replace the pivot bearings myself. Also below is my Masi CXGR gravel bike which is built with a mix of Ultrega and GRX, soon to add their dual control hydro brake levers. It can run racks and fenders for commuting to work, or run gravel tires up to 1.9" diameter. Its a pretty quick and versatile bike.


Living in dry CO, a wax based chain lube is great here. It limits the attraction of dust to the chain and just keeps everything cleaner. I've been using Squirt, which is a wax lube suspension in water. Very easy to apply and it lasts for alot more miles than you guys are quoting. Generally I'm getting 500 miles per cleaning and about 250 between applications. I rotate chains every 1000 miles and keep 3 per bike to reduce the impact of chain stretching on the gears. That significantly increases chainring and cassette lifespan.

The wax that counts is the wax in the chain, not the wax outside of the chain. This is why we quote the miles we do. If I cared about the wax on the outside I would only wax every 1,000 miles or so, or till the wax on the outside is gone. Since I am more concerned about roller wear, I wax every third ride or 120-150 miles which ever comes first. It's like the Jeep engine, if I spray oil on the block and don't put anything in the pan something is going to wear.

I understand the function of the chain lubricant. I was a bike mechanic for a very high end shop in Colorado while I was in college, and my degree is in Metallurgical Engineering and Materials Science. The shop's customers at the time included MTB world champions and Tour de France riders.

Squirt is a wax lubricant suspended in a water solution which came to market about a decade ago. Its easy to apply and you don't have to remove the chain to do it. You put a drop on each roller (don't just stream it onto the chain) and then run the chain about 20-30 rotations and wipe off any excess. It penetrates into the rollers until the water evaporates and then stays put. It tests extremely well in every magazine test, and like I said, you'll have longer intervals between reapplying in dry conditions. It just isn't all that well known. I've finished multiple 100mile MTB races on a single application of it and done well over 500 miles on a road bike on a single application if I don't get caught out in the rain. I've probably gotten 1000 miles from a single application on a road bike, but I've never thought to track it, which is a great endorsement. The stuff just works really well. A .5oz bottle is only $5 on Amazon if you want to try it and a 4oz bottle is only $12 and will probably last you several years.

I'm just suggesting it because I think you'll be really happy with it if you live in a area with dry lubricant is appropriate. I would never recommend changing just before a major ride, but I think you'll really like this product if you try it. I've ridden on alot of different products over the years and this has been the best by far for dry weather.

BTW, the wear issue with the chain on the gears is not due to dirty rollers. Over time, the force you exert on the chain causes it to stretch ever so slightly. As the chain stretches the links space further apart than the teeth in the cogs. This creates wear on the leading edge of the tooth as the roller rides into the cog, ultimately leading to misalignment on shifting. This stretching can be measured with a chain gauge. I believe end of chain life is .75mm of stretch occurs over 12 links. That's an almost imperceptible difference per link, but you can measure it with a gauge.

Thanks, I know what Squirt is. I like waxing my chain the way I do it now. I have used all the gimmicky products over the years and I get longer chain life waxing my chains the way I do. Chain wear is .5 to .75. On an 11 speed it is .5, when it drops .5 the chain needs replacing. Wear on 10 speed and below have higher tolerances. Since I use 11 speed it's all I care about. Anyway to each his own. Time for me to ride.

A couple days left to the 120. I have changed what I am eating the next couple days to insure the intestines are relatively empty. I feel better riding when they are. The temperatures won't be bad when the sun comes up, but when I leave it will be 40F. 48-50 would have been great then I could have worn shorts, but now I have to wear the long things I detest. Once the blood is flowing in my legs I don't feel the cold but until a few miles in I feel it. My upper body which is not moving and catching the air is what I try to keep warm.
I just don't like wearing the long stuff on my legs.

The wind won't be bad for half the ride, coming back it will be a bit gusty, but this is only bothersome along the Gulf where it is wide op and nothing to block wind except me. LOL


Where have the cyclist been? I have not heard from a couple of you all in a couple weeks. Maybe it's too cold to ride where you all are.

My dirty, unsophisticated, no name, slow bike, with nice clean, waxed drive train is nearly ready for tomorrow. It just needs a water bottle and a rider, which will go on the bike tomorrow morning around 0400. The weather is still looking okay, still going to be 40F in the morning, and winds are forecasted to be a little breezier. I think the front coming thru arrived a little later. No matter the winds are still better than last years gale force winds. TTYL
