Re: First DIY Build - input needed (I read the FAQ!)

It's funny how surprised people are how much your pedaling is extending your range... actual pedaling def makes a big difference! I would stay away from the Bionx system. They were way ahead of their time on quality when everything else was pretty low tech... but it's such a closed system, really ha...

Re: cable operated hydraulic brakes

Yes..the Spyres are nice units. The pads can be individually adjusted so as long as you have the allen wrench you should be able to recenter if its rubbing. And they leave you time for plenty of extra drinking according to their ad copy in that link. :wink: No matter what ones you pick, ordering spa...

Re: cable operated hydraulic brakes

For AW... "If you have rims that have the "wear line" you can generally predict when to change the rim out, so that its not unexpected. :) But sometimes that wear line is made in such a way as to allow failure, or something else happens (like a big hit on a pothole or curb jump) that fractures it th...

Re: cable operated hydraulic brakes

Yes... the BB 7s are hard to beat for ease of adjustment, along with having bigger pads than the BB 5s. Theres a few designs coming out that move both pads at the same time, unlike the BB series where only the outside one moves, but they are all crazy expensive and hard to find pads for. You also lo...

Re: cable operated hydraulic brakes

It's a trick of the light.. the rim has machined sidewalls, the kind with two grooves cut into it, and you can see the silver grey color near the bottom on the first pic.. It was def pad wear combined with high PSI tires. But I would agree the manufacturing didn't help by having one of the outside g...

Re: cable operated hydraulic brakes

I'm sure it happens sometimes, but I've never seen a properly set up hydraulic just completely fail. Even the ones that developed leaks didn't suddenly stop working but got gradually mushier as the fluid levels dropped, until the customer finally brings it in when its dead empty.. But I have had cab...

Re: cable operated hydraulic brakes

Many of the times I've had customer bikes come in with the levers to the bar, all the was needed was setting the reach adjust and the brakes were back to perfect. Other times the mushy feel was from someone using the wrong size bleed block, resulting in the system being underfilled. Maybe it's the d...

Re: cable operated hydraulic brakes

BTW, I thought one of the main advantages of hydraulic brakes was that they reduced slop in the system. Running a cable to a hydraulic caliper would take away that advantage and reduce effectiveness. If cable flex is a significant part of your problem, then maybe some of the new hi-teck synthetic c...

Re: cable operated hydraulic brakes

I've messed with those a little, and honestly they seemed a little over priced and underwhelming. The stopping power wasn't markedly better than well set up mechanical discs. You still have to contend with the pads closing up while the front wheel is out from accidental pulling on the brake cable. T...

Re imitation Power Poles, the last batch I got looked the same visually, but were noticably out of spec when trying to hook several of the housings together... They either would side part way together and jam, or be loose and pop apart. It seemed like the plastic started deforming at lower temperatu...

Re: Solar Kiteboat Electrical Needs

It's not that its in the wrong section... Its just that ES is more about EV powering with a motor, not so much boat electric layouts. You might get more response on a boat themed forum, or a solar oriented one. There's a little of what you want on here, but its mostly about putting current to a motor.

But its more expensive due to the miniaturization and clear thermal potting etc, as opposed to big boxy regular controllers.

Re: What are the differences between CAv3 and ERT controllers?

Cycle Analyst integration usually means there a plug hanging out of the controller to plug the CA into, but the CA isn't included. The second controller is a bigger more powerful one, that goes to 72v instead of just 60v.

Actually, the two bolts with the hot wires are highly discolored compared to the other one... I'm still going with simple loose nut causing things to get hot.

Re: Melting wires

Everybody has their own favorite techniques of course. Some of it is application specific too... I make a lot of boat wiring harnesses, and the boat wiring codes are anti solder for some connectors. Then there's other ones like assembling the sevcon multi pin connectors where you can't really solder...

Re: Melting wires

Sometimes solder can wick up the wire strands and make a hard spot that after the wire is flexed a lot breaks the strands, and uncleaned flux can hide down in the wire... properly done crimps have proven to be a hard to beat method, but like most things, dependent on the right tools and technique.

Re: Melting wires

Yes, it could be that those yellow blocks go hand in hand with the terrible poorly plated tiny ring terminals. But if you assume the crimps were all about the same quality (not a great assumption) then seems like how tight the nut is staying could have a lot to do with uneven heating. Modern gold pl...

Re: Melting wires

Just about anything is better that those yellow terminal blocks. I've seen so many of those melt down. Bullet connectors, Anderson Power Poles (not the generic copies) or just straight crimping them together all will be better than the yellow block.

I would have to say my recent experience indicates rather the opposite. I have a three unit modular battery pack, one is shaped for the lower rack, and the others on a rack above the top tube. I used to habitually run the lowest one, and one of the upper ones for medium distance, but was working rec...
