My shop recently glued up a set of Clement MXPs for me using Tufo Tape and layers of glue. I’ve since been doing some research and found that there’s a bunch of negative reviews about this method, but most seem to reference Tufo Extreme and Tufo Regular tape. It seems Tufo has updated their tape since most of these reviews with just a general Road tape option. I’ve found one review on this presumed newer tape that’s favorable but no other information.
Have you heard any feedback on Tufo Tape and CX recently?
I checked with Tufo, and the response I received was, “no changes, one tape for road, one tape for MTB, no tape for CX.”
I have tried what your shop did, and I can say that Tufo road tape didn’t work adequately for that application. I used a combination of both Tufo Extreme and Tufo standard road tape and glue about five years ago on a number of cyclocross wheels, and all of them either rolled off in races or would have if I hadn’t re-glued them. I did roll three of them in races before I had the sense to pull them all off. The Tufo tape delaminated (it’s a multi-layer tape), and the tires came off incredibly easily. It’s possible that the glue caused the tape to delaminate, but I know that adhesion without glue is also insufficient for CX with Tufo road tape. I recommend you have the shop re-glue those tires; at least pull one off to see what the adhesion is like before you attempt racing on the other one.
I’ve also tried a combination of Velox Jantex tubular gluing tape and layers of glue, and that also didn’t keep the tires on. I rolled three of those in races, too, before I had the sense to pull them all off.
I only recommend gluing CX tires with Cyclocrossworld.com’s “Belgian Tape.” Here’s the method, and it also mentions my preliminary experience with Tufo tape and glue in CX; unfortunately, the photos showing the gluing process as well as the delaminated Tufo tape were not archived with the article.
I live in Minneapolis, and with all the new (sort of) road bikes with disc brakes, larger tire clearances and fender mounting, I’m considering a wet/cold weather commuting bike. My question also pertains to fat bikes, which are very common up here.
I’ve looked all over the web, called a few manufacturers, and no one seems to have good information about cold weather performance of disc brakes, whether operating or storage. I’ve seen mention that mineral oil should be stored at room temperature, but that’s very generic advice, and that DOT fluid will absorb moisture.
What’s best in the cold — mineral oil, DOT fluid, cable, or cable/hydraulic with mineral oil (TRP HY/RD)?
Since hydraulic disc brakes work so much better than anything else in warm and down to quite cold weather, and since there aren’t too many days each year that the temperatures in Minneapolis get down to -10F or colder, I’d still use hydraulic discs. Given that the viscosity of mineral oil and DOT fluid is about the same to start with, I’m willing to bet that the added sluggishness both of them develop in deep cold will be similar.
Below are some answers from some diehard winter riders.
From an any-weather rider in Winnipeg:
“I like mechanical disks for really cold weather, especially if you store your bike indoors. A warm rim planted into soft snow will instantly render rim brakes useless, as the snow melts onto the rim and freezes again. That said, I rode with rim brakes for years, and got by okay. I recently rode with a guy on expensive hydraulic brakes in minus 25C (-13F). He said they worked, but were a little slow. I would stick with less expensive, more robust cables.”
From a dedicated New Hampshire fat-bike snow rider:
“I really have never had an issue with my hydro discs in the winter, aside from sometimes (and this is only an Avid issue) some howling. That being said, I recently switched to the new SRAM centerline rotors and they are very quiet so far.
I also have always run the organic pads instead of sintered. They wear faster, but have much better performance right out of the box.
I personally love my Avid Trail 9 brakes, but next time around I’ll be switching up to the new SRAM Guide brakes.”
I have a question for you about road tubeless tires. I was doing my Milano-Sanremo impression yesterday by riding in snowy weather, when I flatted my rear tire. It’s a Hutchinson Fusion tubeless, on a Bontrager race 29 tubeless wheel, on my CX bike. I went to put a tube in, but spent 30 minutes in the cold just trying to get the tire off with no success. Eventually I had to call a cab before hypothermia set in.
In my warm living room this morning, the tire comes off by hand in 10 seconds. I’m assuming the cold yesterday (~34F) shrunk the bead, locking it in super tight? But that’s not really workable if I can’t change the tire in an emergency. Is there a magical tool I don’t know about for cold weather removal, or do I have to switch to clinchers for the winter?
I think the answer is that there is no such magical tool. I asked a bunch of tubeless riders, including Stan of Stan’s NoTubes itself, and they all said they hadn’t run into that before. So I don’t imagine a tool exists for something that not many people run into. I can’t personally remember changing a tubeless tire at freezing temperatures.
I’m assuming that you meant “around 34F” (i.e., just above freezing) and not “-34F”, when you wrote “~34F.” But if you actually meant you were trying to change a tire at 34 degrees below zero Fahrenheit, then I think there’s a deeper issue here, in addition to the fact that the sealant would be frozen.
If you ride above the freezing point, and even within a few degrees below it, you’re still less likely to have a flat if you are running tubeless tires with sealant than if you’re running tubes. So I’d still tend to stick to tubeless tires for their reliability and chalk this one up as a one-off that you probably won’t ever have to face again.
I have Shimano shoes with hard/slippery plastic bottoms and Look cleats with hard plastic bottoms. No matter how much I tighten the screws (I am strong) they slip after five or six spin classes.
I have tried Loctite blue and red they still slip out of my desired position. I weight 185lbs and spin pretty hard.
Try gluing a piece of sandpaper, rough side out, to the bottom of the cleat; I suggest using contact cement (put it on both surfaces, allow them to dry, then stick them together). Once it’s glued on, trim around the cleat and in the cleat holes with a razor knife. The sandpaper will dig into the hard shoe sole and keep it from slipping.
I also wonder if Park Tool’s SAC-2 SuperGrip Carbon and Alloy Assembly Compound might work. This stuff is amazing at how it makes a carbon seatpost that constantly slipped down become super difficult to pull out of the frame.

There are two things confirmed on the 2015 racing schedule for Nairo Quintana: the Tour de France, and now the Tour de San Luís. Anything else remains to be seen.
Race officials confirmed that Quintana will debut his 2015 season at the Argentine race in January, setting the stage for a highly anticipated return to the Tour in July after skipping it in 2014 to race, and win, the Giro d’Italia.
“The rest of [Quintana’s] schedule is not yet confirmed,” said Movistar manager Eusebio Unzué in a press release Tuesday. “But since winning the Giro, he only raced the Vuelta a Burgos, and a few stages at the Vuelta a España, so we believe it’s important for him to start early, but calmly, because the goal is in July.”
Last year, Quintana delighted South American fans with victory before returning to Europe. With one eye on the Tour for 2015, Quintana might not be flying hot out of the gates in January, especially in light of a nagging shoulder injury related to a nasty crash that forced his exit from the Vuelta in September.
The San Luís tour, set for January 19-25 in northern Argentina, has quickly established itself as a favorite for top riders to kick start their respective racing seasons.

Van Moorsel calls new standards "apples and oranges"
Britain’s Sarah Storey will be the first woman to attempt the world hour record since the rules were updated in May of this year. She will make her attempt on February 28 at the Lee Valley VeloPark in London, according to the UCI.
The current women’s record is held by Leontien Zijlaard-van Moorsel, who rode 46.065km in Mexico City in 2003. That record was set under the old Athlete’s Hour rules, which required that equipment and position emulate those used by Eddy Merckx for his successful record attempt in 1972. Storey will be allowed to use any bike and position legal under current endurance track racing regulations, providing her with a significant aerodynamic advantage.
Storey has won six gold medals in cycling at the Paralympics, in addition to five gold, eight silver, and three bronze medals won in swimming, making her Great Britain’s most decorated female Paralympian. The 37-year-old was born without a functioning left hand and also competes against able-bodied athletes on the track.
“I’m excited and nervous at the prospect of being the first woman to take on the record in over a decade,” Storey said. “I did a couple of days’ testing up at the Manchester Velodrome to try and work out the output that would be involved over an hour to have a realistic chance of challenging the record, and we decided that if I can arrive in good shape I stood a fighting chance. Logistically it fits in just about perfectly with the plans I already had put in place for next year which center around the UCI Para-cycling Track World Championships at the end of March — when I will be entering the individual pursuit, 500m time trial and scratch race.”
UCI President Brian Cookson, who pushed for the modernization of the UCI’s hour record rules, was pleased that the women’s record would be tackled. “In amending the regulations, the UCI hoped for exactly this kind of motivation from the world’s best athletes,” Cookson said. “Dame Sarah Storey’s attempt will be eagerly awaited, and I am sure it will prompt other top women riders to try to claim this prestigious record.”
Fellow British athlete Alex Dowsett has made no secret of his desire to tackle the men’s record, and Cycling Weekly reported last week that the Movistar professional may make also make his attempt at the same Revolution Series event in February.
Since the UCI updated its hour record regulations, two men have successfully broken the record. Jens Voigt set a mark of 51.11km in September, which was quickly surpassed by IAM Cycling’s Matthias Brändle with a distance of 51.852km.
On Sunday, Molly Shaffer Van Houweling set an American hour record on the track in California, riding 44.173km.
