I got some nice road rash once when a sewup-err-tubular rolled off my rim in hot weather flying down a grade going 50MPH+ (hey, thats what the guy in the car behind me said I was doing. I lived where it was usually cool, so generally used the gummy tubular glue (Mastik or something?), and not the dry hard stuff (Clemenit?), because it made it easier to swap a flat tire.

Sewups-er-tubulars were wonderful riding, but I switched to 700c clinchers in the mid 80s, and haven't looked back

Clement was my favourite at home and in the shop. I never had or knew of one that failed, but I know it can happen. You needed to be like Merckx and dump water on your tires as you descended!


When I was at the US Olympic Training Center in about 1989, they used a 3M product which I think was used for automotive trim--- somethingbond. It did fail more than once and the one time I was able to see the tubi afterward the adhesive had failed cleanly, staying with the tire but none of it remained on the rim.

The fun part was at the bottom of the descent, the road went into a nice right hand sweeper that would cause you to drift over the double yellow into the oncoming lane, just a couple inches. Talk about a rush. None of the guys I rode with exceeded the low 60's, but they weighed less and used their brakes (brains).

Fastack. Works really well if it absolutely HAS to be glued on RIGHT NOW. Dries quickly. Like in 20min quickly. Only problem is when you go to take the tire off, the base tape usually stays with the rim. AMHIK

...and while I don't condone this:

I completely understand it

Kinsman Notch, NH Hwy 112 going East--12% for 2 miles, wide open. Went down that one with a big guy, and he said his CateyeMate showed 65 the last time I slingshot-passed him.

I did a Texas hill country tour in 1979 with two other riders. They were on a Schwinn Paramount tandem - these guys were twins and they were outstanding riders. Back then, Whit Snel had the Schwinn franchises in San Antonio (owns Bike World today) and these guys both worked for Whit.

When we were going down hill, that tandem would take off like a locomotive going downhill. Often, when we'd hit a big hill, I'd reach over and grab their rear rack. It was like the hand of God was giving me a shove. I must have been more stupid back then than today - inches away, one hand on my bike, the other holding on to a tandem.

Sheesh.... that was fun.

That is amazing. I just have a mountain bike, and it certainly is geared pretty low. Going down a hill in the highest gear and pedaling as fast as my 59 year old legs could go, I hit 26+ mph according to my bike computer. I only ever use the 7 highest gears, and where I ride I never even have to stand up going up the long, but not too steep hills. When I wear out the sprockets and chain, maybe I'll go to different gearing for some more speed.

i tried Fastak when it was the craze back then, but it didn't seem like it did as good of a job holding more than just the rim tape on, and didn't leave much stickiness available for the rare occasion that i had a flat and needed to swap in a pre-glued spare,... i never rolled a sew-up, but a housemate of mine did, and i didn't want to wait until it happened to me.

once i discovered Continentals and the matching Conti glue, the only other flat i ever had was due to a wood screw i picked up in a sidewall that no tire would have survived. (this sucker actually dinged a chainstay as it turned past it.)
Contis weren't cheap, but they rode like they were made for a God (which i certainly wasn't, though i appreciated the ride!). after using them for a while i had so much confidence in them that i wouldn't change them out until i saw cord, even if they looked like cheese graters.

i think you might have your hi/lo gearing mixed up; just like on a motor vehicle, lo gears to go up hill, high gears coming down.

nonetheless, don't expect to see as high a speed descending on a MTB as you would on a proper road bike; the fatter/chunkier tires, flat bar and upright riding position are all working against you in wind and rolling resistance.

much to the chagrin o' many a squid, on a good road-racing bike on a steep twisty descent, i'm likely to be able to keep up with and pass sport motos, mostly due to the ability to brake harder and later before turns. knowing this always spooks me when i'm working Moto Ham at an event, since i'm fully aware of how fast a road bike can actually corner, and how hard it actually is to stay out of the way.

Da 7700 b 53t

Kinda off topic, but I just slapped a new chain on the skinny bike, and noticed the 53 T ring was a bit hooked. I have DA 7700 cranks that are still in good shape, except the clear coat has cracked in places. I replaced the rings 3 or 4 years ago, and need the big again. Does anyone have one, or know anyone that does? TIA!

haven't got one, but am curious why you'd be wearing out the 53 so relatively fast; spending too much time on the 53t while on the large [edit: not "small", doh!] cog(s)?

I don't remember the names, geez its been like 30 years, but the glue I used was like a rubber cement and stayed sticky/rubbery, while the other was red and dried to a fairly hard crust. the red stuff was better for hot inland conditions, but in cool coastal California I usually used the rubbery kind as you could slap a spare on the rim without regluing on the side of the road, as long as you took it easy on the turns. There was a different glue we used to glue the rim tape to the carcass.

I quit running tubulars when A) I was spending more time on my first generation mountain bike, and B) the clement factory had a big fire or something, and their classic setas became unobtanium. I'm reading now that Pirelli had bought them, and moved their production to Thailand, whihc no doubt contributed to their oblivion, but someone recently acquired the rights to the name, and is makign Clement tires again... in Thailand :-/

isn't the big ring where you BELONG when you're on the small rear cogs? its small+small (and big+big) that you want to avoid.

I spend a lot of time in the big ring(When I'm fit), but think I'm pretty good at selecting the right ratio. Maybe some of the teeth are supposed to be pre curved for shifting or something, because overall it looks pretty good. It certainly shifts like buttah. Chains are easier to find anyway...
