Regarding disc brake upgrade: I have cable actuated hydraulic brake calipers (TRP Hy/Rd). They're outstanding! Much easier to maintain than full hyadraulics, works with "regular" shifters and the performance difference is negligable. I've had full hydraulics and high end mechanicals, but the cable actuated hydraulics brake calipers are my absolute favorite. Perfect compromize between ease of maintanance and performace. There are other makes and models. My experince with the TRP Hy/Rd have be falwless

Be aware that the Hy/Rd don't play well with all STI-levers/"brifters". I tried them on my SRAM Rival1 levers and they didn't pull enough cable to fully engage the brakes. You can buy a modification to the Hy/Rd piston mechanism that requires about 30% less cable travel and that would probably have solved my problem. I sold them to a guy who had Shimano controls and they worked perfectly.

@@larsgustav.gudbrandsen I have mine paired with rival 1 shifters too. Initially I thought I had the same issue. But just by pumping the brakes vigorously after dozen times, the pistons selfadjusted and the problem went away. When I was trouble shooting I learned two important lessons: a) use compressionless brake cable housing and b) do not adjust the cable tension so as to "pre-load" the brakes. Just set it up according to the instructions and keep braking and let the hydraulics do their magic self-adjustment.

Joel - I upgraded from Avid BB5 to a pair of TRP Spyres. The Spyres are fantastic mechanical disc brakes and a simple transition on a mechanical-setup bike - no need for new shifters etc. Spyres also have modulation on both sides of the pad meaning you can dial each pad in or out independently.

Agreed. The Spyres are far superior to the BB5 and most other "single-sided" mechanical calipers. They are also super easy to maintain and set up.

Regarding endurance riding, I chose the Orbea OMX. (It’s ready to go, but can it get here through the pandemic?) Like many of the latest drop stay bikes, it has discs, has some aero features, is stiff, is lighter and more comfortable than an aero bike, can take 32mm tires, and has a moderate geometry. A true all-arounder. There are a few bikes in this category that could work without going for a full-on, relaxed, endurance bike. Get shallow wheels if you climb, deep wheels for aero, 25mm tires for quickness, and 32mm tires for comfort and light gravel. N+0. Can’t wait for it to arrive!

For over ten years I rode a stiff-as-hell Pinarello Paris aluminium race bike for training and recreational riding and never had an issue with it. When I hit 60 it began to feel a little less comfortable, probably as my body was aging and becoming less flexible. I bought a Lynskey gravel bike last year (and so even more relaxed than an endurance bike) and stuck some race wheels and tyres on it. It was a revelation in terms of comfort and was really only a smidgen slower. In other words, age matters - what you can ride happily at 30 may leave you limping at 60, at least in my experience.

Regarding chimneys, not all setups need a spacer on top. Cannondale Si setup on a CAAD12/ last model Supersix state *NO* spacer on top, with steered cut down below the top of the stem. The top cap itself supports the steerer where the top bolt of the stem is clamped, with the lower bolt being supported internally by the expander bung inside the steerer. If you put spacers above the stem it can result in the expander and top cap being in the wrong place. Instead would recommend those with OEM parts to check the manufacturers instructions, and if you use aftermarket bits to use your noggin to work out what's best.

One reason sitting on a saddle can be less comfortable indoors is sweat. Even with fans, you still get less wind on your lower parts which makes more difficult on long rides. One thing I had done is put an extra fan behind me. I also build one of those DIY rocker plates (there's a FaceBook group of rocker plate DIYers). They are great. People think they're for simulating rocking your bike when riding out of the saddle. They are more for comfort because your bike keeps moving slightly and it makes a great difference.

On the subject of upgrading mechanical disc brakes, you can by changing out for center pull or by changing to larger sized discs. The center pull calipers will pinch on both sides and be more consistent than single piston calipers, and the larger discs have more leverage resulting in greater stopping force. Just be sure to get the proper adaptor for a change in rotor size.

This is really interesting! If you look at it from a physics perspective, assuming that the tire volume doesn’t change, the pressure in the tire does stay exactly the same (as is ideal gas law PV=nRT states). As the pressure stays the same, so does the force that pushes the tire against the tarmac, hence the ride quality is the same too. In a realistic scenario the tire might even expand a little, because there is less force pushing form the outside, so the tire pressure should decrease.
@skydave93174 жыл бұрын
There are 2 measures of pressure going on here, *absolute* pressure and *gauge* pressure. As other replies state, *absolute* pressure stays the same, or will decrease slightly as tyres are flexible and the volume will increase slightly. On the other hand, *gauge* pressure, which is what you measure when you are pumping your tyres, is the difference between absolute and atmospheric pressure and this will increase as atmospheric pressure decreases with altitude. Because it's the absolute pressure which gives the support to the tyre, the ride quality will not change with change of altitude.

Hi #AskGCNTech, the show that gives me a reason to know the days of the week during the lockdown in France. I bought last year an old Lapierre Tech 7 for its components. Since I am stuck at home, I took the frame out of the attic to see how I could build a sweet commuter bike with it (I had tried the bike and it handled very well), and when removing the derailleur hanger, noticed that the frame was cracked at the junction between the seatstay, the chainstay and the dropout, just behind the hanger. The crack goes through the thread you screw the hanger with. I guess that everyone will jump in to say I should not ride such a bike. So I have two questions: - since it the "thread" still holding seat- and chainstay might give out on any big pothole, in that case am I more likely to need a taxi or an ambulance? - having the frame repaired by a framebuilder will obviously be too expensive given what I paid for this bike, but will it hold if I have it repaired (dare I say bodged?) by a local welder? Cosmetics and extra grams don't matter. Thanks again for running the show which brings us bicycle general knowledge every week!

Maybe you can help me. I’ve the SRAM apex 1 cranks on my gravel bike wanting to get a larger chain ring for it. Somehow all the asymmetric 110 BCD ones only seam to almost fit. Is there any solution to fit another chainring besides drilling into them?

#askgcntech. I am running a Shimano R8000 groupset now with a 50/34 chainset with an 11/30 cassette, but in my daily riding, there is very little chance that I will use the 11 even the 12T. I was wondering is there any way I can change the 50T chainring to a 46 or 48T one while keeping the small 34T ring, that way I can further compress the range of gear ratio while setting the chain more straight when I ride. Thanks!

#AskGCNTech, Hi love your show - thanks for all the good advise! I got Ultegra Di2 and my FD6870 broke. The little "arm" which moves the derailleur up and down snapped (the motor is still intact and works). This "arm" seems its made of aluminum. (after 5 years / 3-4000km per year). I didnt have any crash - it just snapped. Now i am thinking of upgrading that FD to Durace. I learnt it is possible to mix Ultegra and Durace - i would do it if i knew whether this part is made of a more durable (better) material - can you help to get this info - THANK YOU

What do you think of Veers Split Belt drivetrain?

Great episode! I'm looking to upgrade my shimano WH-RS100 wheels that came with the bike, but on a budget. Would be great to have some that can withstand the cobbles here in Flandres. I've found the Vision Comp 35 SL wheels but are they much different in quality and performance? Don't know much about the brand. Cheers and stay healthy!

Now approaching 3 score years and 10 I thought it was time to make things a little easier for myself and get an electric bike (I know, I know), namely a Specialized Creo. The only problem I can see is that they use boost axles, the rear is not a problem but the front is an unusual size of 100 x 12. Can you suggest any wheels that have this size, or a hub, as I can make up my own wheels. Or are there any adaptors to change 100 x 12 to 110 x 12 or is it possible to drop the 110 x 15 down to a 12mm thru axle. Many thanks Yorkstyke

What are your thoughts on deepish (40 or 50s) carbon wheels with a vintage rebuild/resto-mod of 1970-80s steel bike with update modern group set (Shimano 105)?

#AskGCNTech how would you store wheels (with tires inflated)? on the ground or hung up? And does it differ tubeless or clincher?
@freewheels75444 жыл бұрын
I don't think it maters , hung up looks cool tho
@tonymcnally93554 жыл бұрын
Tires aren't of a concern. But you dont want to have anything touch the rim or spokes and fatigue it.

Hi I have a crossbike with a 9 speed Shimano Sora drivetrain and hydraulic disc brakes. I wanted to install a drop bar but found out that there is no brakelever vor drop bars and hydraulic disc brakes. Is there a solution for this? Best regards from Berlin, Germany P.s. love your videos
@arifazhari75984 жыл бұрын
TRP HY/RD is your solution. Many had mentioned it in the comment. Can't go wrong with that. It's a cable actuated hydraulic disc brake.
