Could you guys tell me the spoke lenght to make a 1x or 2x spoke reconfig on my original 2015 front wheel?

My mechanic is respoking my front wheel, and I think radial laced isnt the best for the heavy use i give my bike. I transport my kid on a "standup for brompton" and the shopping basket carries the grocery.



PLUS! I fold and roll the bike as a grocery cart, without the ez wheels.
The bike is so compacted the front spokes hit the frame as i roll the supermarket with the groceries. This stress and the weight has had its toll, ive had to change spokes as they pop up one behind the other...fresh spokes plz!

I dont understand , the radial spoking is head out, to provide the clearance with the fork Blades

Your mechanic is doing it You say, they should be left to figure out out If they are Professionals they can do That

You may find spoke calculation websites , your self ..

you Or they need to gather the data as to the Rim and hub details too.. input that in those Math assistace sites.

really loading it up? get the fork spread to 10cm so you have a more abundant hub choice, then You can seek out a 349 rim ,
custom drilled with 32 spoke holes ..

Phil Wood Co, may be able to make a custom 74mm hub with 32 spokes too , in their California shop.





OR. Just buy a spare front wheel , I have one sitting around because I bought a Dyno-hub wheel, for a Bike I already Owned.

I fold the bike, but keep the handle bars up. So i can push the bike around as a grocery cart. Some movements make the spokes have contact with parts of the frame, i can here the plucking noise from tensioned spokes. And after a lot of use, you can sort of feel were this spokes stress.

Why do you not use easy wheels (or some rollerskate replacement ones)?

Your mechanic should be able to figure out the correct length - otherwise I wouldn't trust him to build a good wheel... Other than that: I think you are fighting a problem that doesn't exist. Brompton front wheels have been radially spoked forever and nobody seems to complain about a front-wheel collapsing. The Brompton is specified for a 110 kg rider plus 2*10kg of luggage - should be enough for most people. Many people (including myself) have been using the Brompton in trolley mode for years w/o a single problem.
If your spokes hit the frame you may have a different problem that you will probably not get rid of with crossed spokes but by searching for the root-cause: Where do the spokes get contact, when and why?

What I've seen once is the front-spokes coming in contact with the axle-nut of the rear wheel if i.e. a S/A 8-speed is fittet that uses wider axle-nuts.

If you want to respoke your 2015 front wheel non-radially you should maybe think about a new/different rim as well, otherwise this may be counter-productive - starting from 2013 on front- and back-rims of the Brompton are drilled differently (front rim for radial spokes, back wheel for crossed spokes). Easiest thing would however be to get a SON-classic-dynamo-hub-wheel. This has crossed spokes plus it deliveres decent light.

Thnx for the replys guys. The correct spoke length for 2015 stock front wheel is 145mm.

You guys are right i bet by adding the ez wheels i would be better of than crossing the spokes. I wanted to ask cause bromptons have many little tweeks. For example im debating using brompton ez wheels, or 3rd party ez wheels, or the offset skate wheels.
The bikes at the shop, so i cant take pics. But i think the spokes get hit, while on trolly mode, when i turn the cart twisting the handel instead of pulling up and swiveling the little wheels.

Regarding EZ-wheels: People used wheels for inline-skates or alike before the EZ-wheels were created - basically this works. Some do it still today because they are cheap. Two Problems:
1. Those wheels are a little wide, so you may hit them with your heels when pedaling.
2. Those wheels are very robust. Thus over time the little metal wings on the backframe where the wheels are attached may suffer more easily from fatigue or break more easily, the latter if the bike get's dropped on the little wheels.

The originial EZ-wheels still are the best choice in my opinion (though expensive). 3rd party alternatives may look better or be cheaper and may be just as good - or not. Give it a try or you'll never know. No risk no fun...

Still the EZ-wheels have nothing to do with spokes of the front wheel hitting the frame when folded - this simply should not happen with or w/o EZ-wheels.
What may happen is the front-wheel spinning when rolled in trolley mode. This is to a degree normal and a bit depended from which tires you use and how the little hook on the front fork is bent as well as from the load and how it is leveled and of course if you have a rack or at least mudguards or not. No need to worry. But if spokes hit the frame there is something wrong that should be fixed if you ask me - you should be able to turn the front wheel freely in trolley mode.

If you feel the roads and your use will cause your stock Brompton wheel to fail.

Again, I Have an extra one to sell, as a back up.

a more direct solution, perhaps?

[I Bought a Shimano - Brompton Dyno hub wheel it uses a cross pattern, they're about $140, built, and ready to go.]
