There’s nothing like having the right tool for the job. What’s your most random/obscure/specialized bike tool?

I’d say any one of these 4. From L to R

Bearing drifts I had made for 61706 bearings. There are a handful of Rotor-sponsored athletes that ran Rotor 3D cranks in their Treks and it was a total rig job to set them up. No setup was the same as the other due to the frame and crank tolerances. I searched forever to find a drift, as the bearings are really, really sensitive. Couldn’t find one. Ended up having them made by a fellow in my hood that had a 3D printer.

Tool I had made for Cannondale SI and Specialized spider lockrings. I know at least 2 also ended up in boxes for world tour teams. Gets rid of the need for a vise.

Roval spoke holder. “Required” in order to warranty Roval wheels. We were sponsored by S a couple years ago and they set us up with Rovals. Way overkill and built like a tank, but damn did it work well. It’s got its own box.

Ergomo bottom bracket tool. Looks like the typical Truvativ external spline bb tool except that one notch is missing, which was removed to make room for the wires in the Ergomo bb. I haven’t ever actually seen another one of these.

Most of my stuff is fairly modern. At this point in my career, I don’t work with much that isn’t at least from the 10s era.

Thanks guys. After a read, I think I understand the loss of forward horizontal momentum due to frame chatter from too hard of a tire. It translates that energy into vertical motion that affects a riders ability to transfer energy into speed.

I’m guessing that is true for any type of wheel and tire combination. There is an optimal starting inflation for each type that eventually rises a bit from heat/friction.

How much does a rider’s weight go into calculating that optimal psi to control deflection, etc to get the best speed for same effort?

If you’re asking if there’s an ideal ratio of weight to tire pressure calculation, I’m sure there is, but again, it’s theoretical and not real world. The high pressures that so many used to run (and some still do) were based on the misconception surrounding friction and contact patch. Not only that, but with clinchers, one had to be cognizant if pinch flats from running too low pressures. Tubeless tires solves that by eliminating the tube which was the part that pinched (as well as GREATLY reducing flats from foreign body punctures.). Personally, I’m 154 lbs. and inflate my tubeless road tires to 90-95 psi. For the record, up until about 15 years ago, I too believed that higher pressures were faster.

I am just a old white man on a bicycle try to maintain a little bit of fitness for my age is all.. As long as I can keep healthy and enjoy all my toys that makes a happy camper out of me.. Most guys my age have a big old pot belly with a 46inch trouser that need to use there walker to hobble to get to the fridge for some left over KFC and a 6 pack....

I happen to weight a 152lbs with a 30 inch waist that can haul the mail on a stupid bicycle..:) YES very proud of it to as I bust my ass every single day to be this way... No scientific method in my madness of bikes and what's right or not..:)

40KM TT Race Feb on The Emerald Isle

So back in Feb of this year I participated in a TT race of 40 KM with over 85 participants to include so pretty elite cyclists of the Island. I finished 7th over all with my average speed of 22.5MPH with a guy from france whom you see behind me who won it with a speed of 29MPH. he is the Triathlon National Coach for Sri Lanka. Please not I was 24 years older then the next youngest guy and I am 67 years old... I gave it everything I had and was worried about blowing up the ticker...

I remember the triathletes asking for 130psi in their 18mm tires. Oof.

I was recently turned onto Formula 1. That stuff, the setups and engineering, is unbelievably fascinating. We think we have dialed setups and procedures in bike racing. But it’s nothing like F1. So much money, so much precision.

I’m 150lbs and went from years of riding 120 on 21mm clinchers to putting 85-90 on 25mm in the last few years. Not only did the ride quality improve considerably, there was an improvement in rolling speeds.

I’m a fat b@$tard 231lbs 6ft 3 49 year old and hadn’t ridden a bike for over 2.5 years over 10 miles until this April when I got put on furlough. 400 miles in April on 23mm clinchers with 100psi switched to 25mm in May keeping with 100psi and did 1000 miles in the month and am now up to 140 miles in a day when I fancy it.

I have come to the conclusion that 25mm are better than 23mm and with the modern thinking of wider rims as well it seems a lot of pro teams are switching to clinchers. I believe Campagnolos latest Boras are clincher now.

Have just ordered a new titanium road frame with Campagnolo Chorus 12 speed and am going for 28mm clinchers on that as I will be using it for touring / endurance riding. Am still sticking with old school long reach rim brakes as I have some nice sets of wheels to go on it but have upgraded the brakes from Tektro to TRP.

Yes I have more then 25 new bicycle but choose to ride this bad azz work out machine.. Kiss this bad boy GOOOD BYEEE. Can it be fixed, yes, am I messing with it..? NOPE..

So in the am I will be riding a bike I own that has ZERO Miles on it with "TUBULAR WHEELS" that I have never ever logged one single mile on.. So I am curious on how the feel is with a set of TUBULARS...

Attachment 1142788
That’s a really cool bike. If it’s the bottom bracket shell on the frame that has broken I can understand you not getting it fixed. If it’s just the bottom bracket itself I’d have got it fixed. Fixies / single speeds are chic due to their brilliant simplicity. If it is just the hub and bottom bracket that need fixing it will be good for thousands of miles more. It’s your bike though so your choice.

First of all, if you were 231 lbs. and 5’6”, I’d say....ride more. Otherwise, you’re good.

I’m with you on rim brakes on road bikes, especially staying away from Campy’s disc brakes. Nobody loves Campy more than me, but they missed the mark with those brakes. By no means a necessity, but if you ever have a chance to ride EPS, it’s nice. We await a pic when you get your new ride!

The best thing about Campy disks is that they absolutely nailed hood shape. Leagues better than anyone else.

They always have. Do you remember when Ergopower was introduced and it looked like a normal lever...and Shimano STI had that weird alien head, ray gun, looking things on the bars? It was embarrassing.

Would ride nothing but 22&23MM Tires and 135PSI and no reason but just because I want to no matter what all the guru's and wizards think...

Whatever works for you is what you should do.

Based on those numbers, I’d say you’re in solid shape. Going wider makes sense.

It is going to be built this week as its quite technical to setup this tap stuff and no way could i ever figure it out... They can build the bike in about 6 hours if they continue at it... I still need to get out my F8 Chris F Rhino Limited Edition..

Wow.

Doing better than me. I'm at 2%.

I know what a bike is (I think) and what a tire is. Or thought I did.

My issues is, if it's for exercise, why do you need the fastest bike and the sleekest clothes. You'd have to work harder with a slower bike and less wind resistant clothing. Hence, more exercise.

I like to think outside the boxes. And boxes.

There's little logic in bike riding.
