Some of the recent 3T stems have a single pinch bolt at the steerer tube (like the first one Carleton pictured). I have one on my road bike and I don't recommend it. In my experience I have to supply more torque than I'm really comfortable with for it to stay put (looking for a replacement). I also have a 3T with the two bolt design and it's great, try to find that if you can.

Is window cleaner ok to use to clean tyres? ( for example before riding on wooden Velodrome?)

I have seen rubbing alcohol and white vinegar reccomended but I was told windex window cleaner does the trick.

Was thinking window cleaner is cheap, doesn’t stink like vinegar and less likely to leak like most rubbing alcohol bottles seem to do. Plus I can clean my window with it haha.

The ti bolts aren't bad. They are just a PITA when you have to carry a special tool to adjust them.



Jimmy Watkins (USA) using a 3T Arx stem on a Felt TK1 (using a standard fork) vs Shane Perkins (AUS) riding a Thomson X4 stem on a BT in the London Olympics:

Not the stem above but this one with the wider bolt spacing on the face as seen on Jimmy's bike. The current MTB stems run a wider spacing, but still not as wide as the older versions. I doubt you'd be able to find any that are new. The titanium bolts on the 2nd tier (red) model are a PITA. I've broken a couple, but never broken when using a torque wrench to tighten. Those older versions don't have them, just the old allen head bolts, but I actually prefer the torx bolts. I think it's a far better design, especially when used for bolts that you work with a lot. I have rounded a number of allen bolts and was due to change out my DA set on my cranks but I just changed to 165 vision cranks and they came with torx bolts and I like them!

Ah. Now I see what you mean.

Torx is the word I was looking for! Torx *is* superior to allen due to the fact that more surface area is engaged. Personally, I prefer ball-head medium length single allen wrenches. Makes for easy spinning in the fingers when slightly off-center.

BTW, one could easily swap allen for torx bolts on stems and crank spiders. I’ve seen the chainring bolts offered as torx in the past. I haven’t seen bolts in the hardware store though.

Aus team ended up making their own thomson style stems after london due to the limited sizing, I've got pictures somewhere that I'll look for.

Interesting.

I wonder if they contracted Thomson for the job. Bike components is sort of a "side gig" for them and they are open to custom work:

Loronzo H. “Ronnie” Thomson founded L.H. Thomson Company, Inc. in 1981 with a mission to manufacture precision machined parts using CNC equipment. In the mid-‘90s, Ronnie used his aerospace engineering expertise to create a bicycle seatpost for his daughter, a team cyclist at Carnegie Mellon University. Rather than making a post similar to other posts on the market, Ronnie created something entirely new: a one-piece seatpost light enough for an unmatched ride, but strong enough to withstand the pressures of biking. Ronnie patented his creation and Thomson bike components were born.
Their main area of expertise is custom aerospace products: https://www.lhthomson.com

Since 1981, L.H. Thomson has been a leader in creating aerospace parts and assemblies through CNC precision manufacturing. By focusing on superior quality and innovative manufacturing and engineering, Thomson has established a reputation for making complex parts to the highest standards and specifications set forth by some of the largest companies in the world.

Utilizing lean manufacturing principles, Thomson excels in the manufacture of monolithic commercial aircraft components using aluminum, high temperature alloys, titanium, stainless steel, high nickel materials, magnesium, plastics, copper, and other metals and composites.

We specialize in long term agreements and we are well positioned to handle start-up costs. Thomson makes your part to print, in tolerance, and delivers it on time. Our in house tool room assures that any fixture and gage can be created at L.H. Thomson – if a tool doesn’t exist, we’ll create it, just for you.
The company is about an hour away from me in Macon, GA.

Hi guys,

Asking for some crank opinions - I’m trying to choose between the following, both in 165mm

DA 7710 crank set, plus 105 5500 bottom bracket -£300

or

Sugino SG75 “criterium” +SG75 bottom bracket, £205.
https://www.dolan-bikes.com/sugino-s...-pcd144mm.html

Theres is not much info available about the SG75 criteriums. I’m not sure if they are the same crank as the normal SG75 but just bundled with a chainring for the crit racer crowd or built differently. They have a different paint job at least.
Im a big guy, definitely a “Clydesdale” as Carlton likes to put it. I push fairly big watts so want a reliably stiff crank set.

What do you guys think? Are the Sugino’s as good as the dura ace? Any benefits to sticking to square taper for example?

Edit - Adding another layer of complexity, alternatively there is the Sugino Direct Drive DD75 crank for similar money to the dura ace at £320.

thanks

Hi Gycho,

Why would your reccomend the 7710 over the DD75 out of interest?

Thanks

Vision track cranks? They're good enough for Van den Berg and Bos on their Avantis. I just purchased a set of 165s to try from Ben’s Cycle. I already have DA 7710s in 175 but the Visions with FSA BB came in cheaper than a new set of DA cranks and they look sexy. I didn’t bother looking at NJS stuff because I got a set of cranks via then a few years ago and the BB interface was damaged and they were slightly out of alignment so decided to go new

Yeah, as much as I love the 7710 cranks with the BB-7710 bottom bracket, the set is very expensive. They are a "buy it for life" type of item, though. And they are the reference track crankset to which all others are compared.

Maybe they keep the price where it is because of that.

For us in Oz, exchange rate is a big part of the issue. When the $$ was good I got my 175 cranks and they were $315. My first track bike came with DA 170s so I was already onboard. Now the best price is $AU450 plus delivery. Relatively speaking they're up there, but so too is the quality.

Nothing wrong with Sugino 75's. Sure, square taper is pre-historic technology, but it still works. I've been using them for 10 years with no problems.

I managed to pick up a brand new set of DA 7710 for just £165 - was a strange situation where amazon showed them as out of stock but you could still order and they would charge when they came back into stock. I did that a few weeks ago and forgot about it, never expecting them to come back into stock at that low price. Yesterday i got a message to say they were dispatched and they arrived today!

Was half expecting it to be a scam with something of similar weight stuffed in a box but they arrived brand new and factory sealed. They are very pretty - cant wait to get them on the bike! Just got to wait for a bottom bracket to arrive first!

I used golf gloves as my "special occasion" gloves for big events. Baseball gloves for training and weekly racing.

All of the above are better than 5Bling in terms of options, quality of leather, and availability. Plus you get to try before you buy. I do like the idea of supporting a small businessman in the cycling world, though.

I've owned 2 sets of 5Bling gloves. I've never used or handled BLS gloves.

Regarding attaching NJS straps to current generation pedals:

I've done it using small/narrow zip ties with Ultegra carbon pedals. No drilling/shaving required. I'm sure people have pics out there from others. I now have them on my road bike.

I hunted for some alloy Dura Ace PD-7810 and Ultegra (forget the model) which are PERFECT for attaching pedals. Note the metal tab in the center.





Hi Carleton, i just noticed in these images you posted that on your NJS straps you have the straps crossing front to back rather than going into their naturally corresponding buckle - is there a reason / advantage for doing this? Or is it just a case that thats how the straps fit easiest with the zip ties?

Struggling to get mine on quickly so looking for any possible advantage. British cycling marshals are not very accepting of faff!

It's to allow the straps to come together under the pedal.

I could just squeeze them closer, but they don't want to do that. If you cross them and let the cross point be under the pedal, it works better and you get what's in the photo above.

There are quite a few on IG. I recently deleted all of my bookmarks of several sprinters while periodically editing my bookmarks (nothing against them).

I think that IG is an easy way for them to fulfill the "Social Media Obligations" of the contracts that many of them have. Basically, sponsors require them to highlight their products.

Many of the posts are passively promotional by nature. "This ACME XYZ2000 Power Meter showed me just how hard that race really was!" Many are not. Some are basic IG stuff, "look at this PR I hit in the gym today!" or "mmmmm...espresso!"

I think the best part is seeing what components they actually use in normal training and racing.

I know this doesn't directly answer your question. But, if you get hold of one, you can read the comments section of the photos and spot the teammates and competitor friends. For example:

There you'll find the IDs of Sir Chris Hoy, Joe Truman, Jack Carlin, Mark Stewart, Ollie Wood, Kian Emadi, and Ryan Owens all of Team GB.
