What are the Correct Replacement Bolts for mounting your Bicycle Kickstands? 3/8″ – 16 TPI BSW Whitworth

What are the Correct Replacement Bolts for mounting your Bicycle Kickstands? 3/8″ – 16 TPI BSW Whitworth

Replacement Bolts for mounting your Kickstands are most likely a 16G 3/8″ Whitworth 55 deg Thread with a nominal metric diameter of 9.525mm, so close enough to M10 x 1.5mm but not quite, you’ll probably have trouble getting it to start although it may bit a little it’ll jam if you really try it or just take off the first thread.

It’s the kind of bolt you want to do up nice and tight, often util the mounting plate flexes under the bolt head, around 20 N.m / 14-15 lbf.ft Torque


The Correct Bolt

3/8″ 16G Whitworth 55 deg, 2″ Long, HEX Bolt (14mm Spanner, not 9/16″) with a Full Thread, preferably BZP Bright Zinc Plated, or Stainless Steel

75% tap
drill size
(in) (mm) (in−1) (mm) (in) (mm) (in) (mm)
3/8 9.525 16 1.588 0.2950 7.493 516 8.0
0.375 9.82 16.333 1.588 0.3212 8.16 2164 8.2


So where do you get one of these? It’s a rather obsolete, and unobtainable part as bolts go, it’s a hard find. It’s the kind of thing you’ll find in a large selection pack of bolts, if you’re lucky you’ll have one in with your M10 bolts or close to hand.


What if I can’t find the correct bolt?

What’s best to do if you can’t find this rather obsolete bolt, what if I can’t find the correct bolt? Well given it’s size that it’s very easy to tap if you’ve got a bolt and tap set, I’d recommend that.  It just so happens the hole size is a good fit for the ISO Metric M10 x 1.5mm Bolt Thread Tap being around 8.25mm ID it’s a fraction undersize, but use lots of cutting fluid and it’ll make a good thread. This doesn’t work if you’ve got a striped thread, or if ,maybe the hole on your Chainstay welded or brazed-on kickstand plate

There are of course taps & dies available if you’ve got a bolt with only a short section of thread, and you may find you can get away with a bolt 1/2″ shorter if you’ve got narrow gauge tubing as the 2″ tends to be a bit longer than required once fully installed, it does however make installation easier and slightly less fiddly having a 2″ bolt.


I’ve seen the topic covered on bike forums . net and after tapping a thread, then finding a couple of Full Thread 2″ x 3/8″ 16 BSW Bolts it made sense to make some sense of it all, as forums are full of small snippets and often lend off topic confusion to the matter. Old bikes are full of strange threads, and a lot of older threads are now hard to come by.
I hope you’ve found this useful, obviously there will be changes to the metric bolts already from many manufacturers and if you’re lucky you’ll never need to come across this article. I’ve just spent a bit of time writing up this article on the mundane topic of these bolts and if it gets enough hit’s and attention I’ll get in some bolts maybe, but it gives a good idea of how to work around the problem and should give enough info to explain everything you’ll give up looking for normally unless you wonder around with a bolt in your pocket or use thread gauges…

Martin Dupre Stolen Bikes Funded – See the results, first build… GHP 24″ Expert

So you may have heard Martin’s 3 kids bike got stolen recently from his car right at the beginning of the season…

On Sunday 13th March 3 bikes were stolen from Martin Dupre’s Car whilst parked securely (at least thought this was the case) in Asda Car Park next to the NCC in Manchester, this was round 1 and 2 of the BMX National Series

Martin has been in touch with Asda but unfortunatley the CCTV are unable to pick up who stole them, due to the location of the camera, so Martin has been left with the headache of trying to replace these bikes!

As most of the BMX community know, race bikes are expensive and Martin’s bikes were of good spec, he has worked hard to try and buy the best for his kids.

it would be great if we can all give a little to help Martin replace these bikes.

Thank you all so much for taking the time to read this and I know Martin and his family will be so grateful for anything you can give.

His successful gofundme netted enough to sort almost everything out luckily so he’e been able to continue the season, your support has meant a lot.
“The support offered has really made all the difference, between replacing them or having nothing!”  Martin would really like to thank everyone involved.

Thank you everyone who helped to raise money for Martin, it is truly amazing how many kind generous people are out there! We have managed to raise over £950 in total (a fee is taken from go fund for their service) and the money is on it’s way to Martin, hopefully this will help to replace the bikes stolen. Lisa xx

Rare Footage from 1976 Kawasaki BMX Race at Saddleback Park

It’s taken a few years but in 2011, Producer and Director Todd Huffman of “The Motocross Files” acquired reels of lost footage from the 1976 motocross series shot by a young filmmaker from San Diego named Ray Baum. The footage had never been edited into anything so after transferring thousands of feet of film into a digital format, hidden in all the wonderful motocross footage was six minutes from this BMX race.

This video was presented for the first time at USA BMX’s 2015 Hall of Fame induction ceremony at the Olympic Training Center in Chula Vista, CA on October 10th, 2015.

Thank you Ray Baum for preserving this and thank you Green Day for writing such a beautiful song that makes us all remember. “Good Riddance”. source: The Motocross Files/YT

Here’s how it started;


News Release
For Immediate Release


(May 3, 1996) Cannondale, the Connecticut-based manufacturer of lightweight,
high-performance aluminum bicycles, is forming a separate division for its
HeadShok line of mountain bike suspension forks.  The company’s new HeadShok
division is busy on two fronts: developing new forks with increased
travel in the traditional HeadShok/telescoping-steerer tube style for use on
its own models, and developing at least two telescoping-blade HeadShok forks
for bikes with standard diameter head tubes.  The two telescoping-blade forks
will be the first HeadShok forks compatible with bikes other than Cannondales.

According to Scott Montgomery, Cannondale’s Vice President of Listening, the
move will help the company to continue its overall focus on innovation.  “Our
goal has always been to produce the finest bicycles in the world.  But
improving the frame alone can only take you so far; Eventually, you ha
ve to improve the fork and other components as well,² explained Montgomery.

“Toward that end, we now have three different bike-related divisions within
Cannondale — our frame division, CODA components division, and the HeadShok
fork division.  Each division is focused on its own particular area of
expertise, but also works with the other groups to form proprietary, int
egrated technologies that, as a frame-maker alone, we couldn’t otherwise
develop.  We call the approach Systems Integration.²  Montgomery added that
each division has its own budgets, product manager and research and development
staff, mirroring the approach that Cannondale has taken with its ap
parel and cycling accessories business.

Montgomery went on to explain that the two new HeadShok forks for standard
diameter head tubes are scheduled for introduction later this year, and will
incorporate the triple-clamp design developed for the Volvo/Cannondale Mountain
Bike Racing Team.  “The new forks, the Moto 120 and Moto 80, are
based on the Moto fork used by the Team downhillers,² said Montgomery.  “Both
forks have the adjustable triple-clamp design that lets you dial-in the bike’s
head angle by raising or lowering the position of the clamps on the fork legs.
And because the triple-clamp approach allows the fork legs
to overlap the head tube — and dramatically increase the distance between the
bushings inside the stanchion tubes — stiction is reduced.²  Montgomery also
noted that Cannondale has already had inquiries from other bike makers
interested in spec’ing Moto forks on their frames.

The Moto 120 is currently spec’d on Cannondale’s award-winning Super V DH
Active.  It features an air spring, 120 millimeters of travel, and individually
adjustable compression and rebound damping.  It is paired with a dedicated,
oversized hub for increased stiffness and true tracking precision.
The Moto 80 is suitable for both downhill and cross-country riding, and has
80 millimeters of travel, an adjustable MCU spring, and oil-damping.  Like the
Moto 120, the Moto 80 system uses a dedicated, oversized custom hub (with a
unique quick-release system) to deliver precise tracking.  Mont
gomery said the Moto 120 will be in bike shops in July, and the Moto 80 will be
available in November.  Prices on the new forks have not yet been determined.

My BMX Bike, 2011 Diamondback NNY

Diamondback NNY

I got this bike quite some time ago, it’s lasted me well with a few additional bits it’s lasted even longer.  I got this for a puerile want of a freecoaster and hadn’t ever owned one so I thought it’d be fun, it was… It came pre-2011 as the spec’d model to sell form it was a good bargain

The original spec;

  • Tubular 4130 chromo 3 piece crank on Affix Mid Bush BB with Affix Artis pedals
  • 25T sprocket with 9T Affix Kronos freecoaster hub
  • Rear U brake with soft compound pad and front caliper brake with alloy levers
  • Front 10mm hub and rear 14mm Affix Kronos freecoaster hub on doublewall alloy rims with KHE MAC2 street tyres.
  • Affix system stem with 2 piece butted handlebar 8.2” rise 28.8” width
  • KHE Loyal saddle and post with custom DB graphics
  • Diamondback/KHE collaboration: Full 4130 Butted chromoly street frame, butted chromoly forks
  • Top tube: 20.5“
  • C/stay: 14.5“
  • Weight: 22.5lbs


So what’s still on it…

Let’s start with what’s not, the bars and lever were the first to go, replaced with  a trusted Shimano XTR r/h V-Brake lever (I know, I know…) and a full size set of S&M Perfect 10 Handlebars. Next, pedals. Plastic crap that failed as quickly as expected upgraded to an old pair of Shimano DX Platform Pedals, running strong after about 10years.

The Cranks have also been worn through, in fact these were’ the first to really go!  The original bearings failed, so a new B/B for the old Profile Racing Cranks and on they went… (these good old cranks have done the rounds, they’ve been on at least four bikes now over the last 15 years)
New KMC chain and chainring followed shortly…
