Bike gear roundup: New releases from BikeTube // 4iiii Innovations // Flectr

Bike Tube Butane Tube Valve

Here’s another dose of fresh gear to get you through the weekend. BikeTube released their Butane tubes that offer a lightweight alternative to standard tubes, plus a low priced hand pump. 4iiii Inovations is selling pre-set cranks with their new PRECISION power meter installed along with providing a custom install service. Additionally, Flectr launched their Gravel Guard frame protection systems that offer self-healing properties and a thicker frame protection alternative.

Get the weights, prices and compatible options after the break.

New from BikeTube are their Butane High-Performance Road Tubes. By using a 0.73mm tube construction and an aluminum valve stem they’re able to shave around 50g off (a pair – varying with stem length) of a standard rubber tube. Stem lengths range from 48mm to 80mm, while tube widths include 18 – 25mm and 25 – 32mm. Butane tube weights include – 700 x 18 – 25c : 74 g [48mm] : 75 g [60mm] : 77 g [80mm] – 700 x 25 – 30c : 82 g [48mm] : 83 g [60mm] : 85 g [80mm]. Weights may vary +/- 3 g. The $8 Butane tubes have a noticeable weight loss compared to BikeTube’s standard tube offerings that use brass valves and weigh about 96 g for a 18 – 25mm tube [48mm valve] and 130 g for a 25 – 32mm tube [48mm valve].

Since you’ll need something to inflate those new tubes, BikeTube also has a new Air Handler mini pump which should do the trick. The pump is pretty compact and includes a switch to go from high volume to high pressure with a price tag of just $12.

  • Patented piston system pumps air in both stroke directions
  • Two-stage switch allows high pressure pumping with minimal effort
  • Patented Auto Head automatically adapts to Presta or Schrader valves
  • Polished aluminum barrel
  • Rated to 120 p.s.i.
  • 6.5″ (16 cm.), 3.8 oz., 107 grams
  • Spare rubber grommet included

The Gravel Guard from Flectr focuses on providing high-impact-damping film to protect your frame from rocks, gravel and day-to-day abuse. The 0.36mm film provides a barrier that’s thin enough to keep the surface from catching against other objects, and thick enough to absorb the force of potential road/trail spray. It also has self-healing properties that keep the guard from appearing damaged after impact. They have five options available through their website starting at €8 for small patches and up to €39 for the XL frame protector kit. They’re also releasing them on Kickstarter where products starting at the €12 pledge.

If I’m going to spend more money on tubes and am willing to sacrifice durability for leightweight and suppleness why not go the full enchilada and drop the extra four bucks for latex. I’ve never understood this mentality, then again I don’t understand the mentality of people who train on race wheels.

latex can melt on certain carbon rims during certain high braking rides

Latex bleeds air pretty fast. Not a big deal for criteriums and short RR’s, but it’s significant enough for some. They’re also harder to patch.

I’ve never patched latex and am pretty sure it’s not worth it do so considering they’d be in race wheels where equipment failure can be catastrophic. I also have done 4+hour rides on them without a significant loss of pressure. I seriously doubt the pro peloton would be on latex tubulars if they bleed air that badly considering their races can last upwards of 6 hours.

Bleeding air is not a problem, I’ve ridden them 48h after pumping in a pinch, still had enough PSI to ride 30 miles to the nearest known pump (i was abroad). Latex tubes are great, they’re lighter, and significantly more flexible which = MORE puncture resistance. However, riding on a butyl tube which is knowingly thinner than a standard tube is just dumb to me. The only benefit is weight, and it comes at an big expense.

74g for 48mm Presta valves is anything but lightweight to crow about.

I had lightweight butyl tubes from Continental with 48mm valves that weighed less. And that was probably a decade ago.

Its 1gram less then performance bike’s lightweight tube using rubber .13mm thicker (though not sure how they attribute stretch making the tubes thinner when installed)

My bike already has a few pieces of clear, protective tape where the brake cable rubs, but this Flectr stuff seems useful.

I just love the artisanal movement; it touches everything on a bike.

Now, can we be sure that these tubes are made using sustainable farming methods? Here’s to hoping that their next stop is conflict-free spoke nipples.

Uhh, did you read a completely different article than I did? Where did you get artisanal or any of your other ramblings?

How is a generic Chinese pump with a logo on it newsworthy?

Did you forget to mention what is new from 4iiii, or is this just an ad?

Just buy bulk rolls of 3M clear bra material. Put this stuff anywhere on your bike you want protection.

Proper lightweight butyl tubes for road are 65g and are drawn to 0.6mm with zero drawbacks besides the slightly higher cost. Bonkers light ones are 0.45mm and weigh 50grams. These are only special when compared to their standard tube.

Are you removing valve cores to inject sealant? If so,what sealant and what has
been your experience?

Why make a lightweight tube and then stick a 48mm valve on it? I won’t ride anything but 32mm valves as I don’t need the extra height (or weight).

Because some people need longer valves?

Many “standard” depth rims on stock bikes are deep enough to make 32’s a little short. 48mm valve has become the industry standard.

an alloy valve stem + =/> weight in sealant will still offer a better ride quality, compliance, and more flat protection.

Alloy valve stems improve compliance?
