Care for your helmet, helps you take care of your scalp

Very often we have customers who refuse to don a bicycle helmet for various WRONG

reasons, from “not necessary” to “messes up my hair”  to ” I am going at a slow speed”  to “it’s too hot”. The bicycle helmets we sell range from S$49 to S$250 and we brought quality to every price category so the economics of owning a helmet is a weak one when you consider the fact that you need protection to your head when someone hits you.

HOWEVER, when it comes to care of your scalp which could lead to itchiness or hair root aggravation, we do ask that you take note of a few things:

1. Pick a good fit for the helmet

Too tight a fitting or too loose can lead to the helmet pulling on the roots of the hair. The scientific name is traction Alopecia. You can easily avoid any risk of traction alopecia due to wearing a helmet, by using a helmet of the right size that is not too tight or too loose on your head. Do  the 2VI method.

While putting on the helmet also ensure that no hair is pulled very tightly by the helmet. Take your time every time you put it on, and continue jiggling and shifting the helmet till you reach the most comfortable position, when no hair is pulled back tightly. Also take care while taking off the helmet.

2. Keep your helmet clean and store it in an airy and hygienic place to avoid hair loss   

As your scalp sweats up due to wearing a helmet, the inner layer of the helmet also gets Shower.jpgwet with sweat. It is also important to clean the inner lining of your helmet regularly and to ensure that there is no fungal growth on the inner soft layer. Store your helmet in a hygienic and airy place so that it can easily get dried up and is not smelly. We recommend you shower with your helmet after each ride. No, you do not need to wear it but shampoo the straps and inner lining ( BUT we won’t stop you LoL)

3. Stay dry Along with the above you can also follow the following tips to avoid any hair loss caused due to wearing a helmet

Along with the above tips, you can also follow the following to avoid any hair loss caused due to wearing a helmet,

  • Every time you take a break between rides, take off your helmet as well and give your hairs and the helmet some time to dry out.Towel down to dry faster
  • Wearing a piece of cloth or scarf on your head, covering your hairs before putting on the helmet can be a very effective way to reduce any risk of hair loss due to helmet. The cotton cloth will reduce any friction between the hairs and the helmet and will also soak the sweat quickly eliminating all the worries. However, always ensure that the cloth is washed and completely clean before putting it on.

Moulton SST – the engineer’s dream

The Moulton Spaceframe is so easily recognised. Unique, iconic, d0258552_17595385

engineering artistry with the frame lattice and just so classy in looks,  it really sets you apart.

HOWEVER…

The stainless steel of Bradford made bikes are the epitome

of the elite when it comes to small wheeled seperable or fixed bikes. Aircraft stainless steel frame but really expensive.

Introducing the New SST. Features the essential Moulton ‘ingredients’ but in a more affordable frame material:

  • Fillet-brazed construction in Columbus Spirit and Reynolds 525 CrMo steels.
  • Moulton leading-link front suspension (with soft rebound stops, hex key adjustment)
  • Moulton rubber-cone ‘Monosphere’ rear suspension, oversized rear pivot bearing.

Unified rear fork with triple-crankset/compact clearance.
Kingpin separability (hex-key operation).

Car-lite beckons and better products are being introduced.

Quote from Prime Minister, Mr Lee Hsien Loong ;

“Car-Lite Singapore” by promoting and developing other modes of transport, making them convenient. We have to rely less on cars on the roads because we cannot keep on building roads – more roads for more cars. So we will provide more options for Singaporeans that are better than cars. Buses, more of course. Expanding the MRT network – that is happening everyday – but also other modes of transport for example, bicycling…”

So as a business having helped many get into cycling and owning a folding bike so you can enjoy the various infrastructure that the government has invested in, we spared no efforts to work with manufacturers, suppliers and level headed opinion leaders on what would work? So we completed our first wave of cargo bikes that have their own USPs and features/benefits.

The Kiffy Flash AND Bike Friday Haul-a-Day.

Kiffy Flash – a 2 speed hub adult trike with a front payload

The Kiffy can be disassembled and transformed into a pushable hand cart for use in a photo-yves-salvatgrocery store. The 4-foot-9-inch-long bike folds down to take up just 2′ by 2′, so it’s easily rolled into a subway car or an elevator. A clever front suspension system dubbed “Swing” allows the front of the tricycle to tilt like a regular bike, providing stability even on slopes. Front disc brakes keep everything under control. The inventor, Norbert Peytour, says that cycling is a form of care-free travel, with no fuel levels to watch, little to no maintenance, no engine that can fail. He rejects “advances” like the electric bike, which add complexity (and fuel consumption) to the mix.

Bike Friday Haul a Day

When Bike Friday Co-Founder Alan Scholz and Kidical Mass Co-Founder Shane Haul a Day alan_.1MacRhodes put their heads together to come up with the perfect versatile bike for a Safe Routes to School class leader, the Bike Friday Haul-a-Day was born.The Haul-a-Day quickly earned a reputation as a great Family Bike as word spread quickly through Social Media by mothers and fathers that the Haul-a-Day delivered a great ride.  Watch Alan Scholz vision

The Haul-a-Day is set up for the ultimate in convenience.

  • Frame adjusts to riders (1.2 m to 2.0 m)
  • Starting weight just 16kg
  • Low step-over height
  • Big load capacity, low center of gravity
  • Light and agile, rides like a real bike
  • Made in the USA

Baby steps but we have to start somewhere and with the rules and guidelines getting better and the encouragement for shared paths and tolerance for other users, am sure we will see more and more folks carrying payloads on their bikes. We think and believe Car-lite will be a reality in Singapore!

Cycling Myth Busters #3 – Balls of ceramic are better than balls of steel?

This blog is really about Steel ball bearings versus Ceramic ball bearings. Enough has written about this subject but I thought I put together the topics the guys are pre-occupied with. But for those who already burn their wallets swapping out all their existing ball bearings to ceramic based ones – the answer is Yes.

First principles:

Metal balls are rolling, spherical elements that are used in check and ball valves, bearings, and other mechanical devices that provide rotary or linear motion.  For us bikers, it means Headsets, Bottom Bracket, Hubs and Cranks .  Surface Roughness measures the irregularities that form on the surface, but are not significant deviations. Basic diameter Tolerance is the maximum allowable deviation average diameter from the diameter specified.   

Ceramic balls are made from inorganic, nonmetallic materials that are processed at high temperatures. Many ceramic balls are capable of achieving an extremely smooth surface finish to a high degree of tolerance. As a result Ceramic Balls have an extremely low coefficient of friction as compared to Metal Balls. Grinding removes cuts, scratches, scuffs, and other irregularities. Many ceramic balls exhibit much greater hardness than steel balls, resulting in longer life and improved reliability. Ceramic balls can also provide high stiffness, low thermal expansion, light weight, increased corrosion resistance, and electrical resistance. A wide assortment of Silicon Nitride Ceramic Balls, Alumina Oxide Ceramic Balls and Zirconia Ceramic Balls are now available.

Ceramic bearings benefits

35% less Thermal Expansion:
Think of putting a coke in the freezer. You have to allow for its expansion or you’ll blow the tin. Steel bearings are like the tin of pop. Ceramics on the other hand change size significantly less then steel with a given shift in temperature, thus raceways, rings and seals from a typical bearing can be made to much greater tolerances. They can even be fabricated with a smoother finish so vibration goes down and stability goes up.

50% less Conductivity:
Ceramics are electrically NON-conductive, and chemically inert, thus do not suffer from oxidation and the rust that degrades the surface of a traditional steel ball bearing. They suffer less heat damage since they don’t heat up as easily. This helps to maintain the spherical geometry of the ball bearings and significantly reduces your repair time.

60% less Weight:
Since silicon nitride is only about 40% of the weight of bearing steel the savings are obvious. Think about tying a heavy rock to the end of a rope. Its hard to get in motion and hard to stop. The lighter the rock the easier it is.

The issue of bearing weight is the same story. The heavier they are the more effort it takes to get them rolling and stopping. Thus ceramic bearings, with less then half the weight, and thus less rotating mass, will be much more responsive in acceleration and deceleration, with much less effort.

50% Higher Modulus of Elasticity:
that’s just a fancy way to test how easy it is to deform something. Ceramic has a 50% higher modulus of elasticity, so it takes a lot of work to alter its original shape. That gives you a much longer life expectancy in a hard wear zone like a bicycle’s bottom bracket.

Cold Welding:
Steel on steel has a nasty habit of welding itself together, that’s why you use anti-seize on some fittings. In a bearing the lubricate helps to prevent this but when bearings sit over the winter this can happen. Ceramic is NOT able to weld itself to steel. Steel and Ceramic are incompatible in that respect so cold welding is another difficulty you can avoid with ceramic ball bearings.

Research suggests that Bottom brackets equipped with ceramic bearings have a 5-10 times longer life. Industrial literature might suggest ceramics add 3-5 times the life expectancy. Either way we know they’ll be there longer than their carbon steel cousin.

Equally exciting, in tests with Olympic and professional racers and in controlled lab tests with wheels, ceramic bearings repeatedly show significantly less friction, making for faster speeds, acceleration and deceleration with less force.

So whats not to like? Only the price. Ceramic Bearings are easy to justify with longer life, less vibration, more speed but at maybe 5 times the price of traditional bearings the questions still remains as to whether you can justify the added cost?
