BSA – Aligning Damaged Dropouts, Frame and Forks

Dropout

Rear Dropout on the Drive Side had been opened up and the forks were also slightly twisted and the drop out was also opened up on one side.

We simply managed to close the gap in the dropout using extra large adjustable pliers, shielded with folded card to protect the metalwork (although to be honest at this stage there’s nothing to protect) we don’t want any gauge and scores or marks we want to file down any imperfections as we go.

The forks were easily pulled back into shape and balanced perfectly just using hand forces the forward leg was corrected and dropout closed up a touch on the one side.

BSA – Buying Parts, Cranks and Bar Tape

BSA-Cranks

Cranks chosen on price, these came in just under £20 with a reasonable ratio to work well against 16 teeth at the rear simple and silver.

Square Taper Bottom Bracket required, I’ll have to wait until I can find something short enough to assemble it, this need something in the range of 68mm X 101mm. Yikes!

 

Grips, covered with Brown! Handlebar Tape… Cost £3.56 Bargain! China Strikes again…

Cheap as chips but it’ll do the job, and work well with British Racing Green for the frame colour.

Wheel Sizes Explained, ETRTO, Imperial, & Radius

Size Markings                                                        
What do the various size markings on bicycle tires mean?                                                        
                                                         
Nowadays, bicycle tire sizes are all marked according to ETRTO (European Tire andRim Technical Organization) European standard.However, older English and French tire size dimensions are still used as well.                                                        
The ETRTO size specification 37-622 indicates the width of 37 mm and the tire inner diameter of 622 mm. This dimension is clear and allows for precise classification of the rim size.                                                        
                                                         
Inch Marking (e.g. 28 x 1.40) states the approximate outer diameter (28 inches) and the tire width (1.40 inches). Inch marking such as 28 x 1 5/8 x 1 3/8 (approximate outer diameter x tire height x tire width) is also common.                                                        
Inch sizes are not precise and lack accuracy. For example, diameters 559 mm (MTB), 571 mm (Triathlon) and 590 mm (Touring) are all classified as 26 inch. Tires with diameters 622 mm and 635 mm are both classified as 28-inch. Oddly enough, tires with an inner diameter of 630 mm are classified as 27-inch.                                                        
These classifications originate from the time of tire brakes. In those days, the exact outer diameter of the tire was defined by the brake. Depending on tire width, various standards for the inner diameter applied.                                                        
                                                         
Inch dimensions are widely used in both MTB sport and English language countries. Therefore, we will continue to use these specifications for all tires. In the future, only inch decimal measurements will be used e.g. 26 x 2.25. Experience tells us that nowadays very few users are familiar with the classical fractional inch dimensions such as, 28 x 1 5/8 x 1 3/8.                                                        
                                                         
When the 29 inch MTB tire size was introduced a few years ago it had the same inner diameter of 622mm, known as 28″ in Europe.                                                        
French size markings (e.g. 700 x 35C) give the approximate tire outer diameter (700 mm) and width (35mm). The letter at the end indicates the inner diameter of the tire. In this case, C stands for 622 mm.                                                        
                                                         
French size markings are not used for all tire sizes, so, for example, it is not used for MTB sizes.

Saturday 20: Brent BMX Club, Dr Bike and Sunday 21 June: ELBO BMX Club

lundy7-crop

Hello Guys & Girls,

We’re sorry to have to announce neither Alex nor myself will be at Brent BMX Club,  this weekend. I’m off to Lundy Island for a few days, maybe a spot of diving, canoeing…
It’s a rare occasion I get a Holiday

It also seems weather wasn’t going to be on our side any how with rain predicted all day

We will be back in action Saturday week 27th June , with our usual support from 1-3pm on Saturday Afternoon.

Alternately for those interested a national BMX race is happening on Saturday.

I hope you all have a lovely weekend and I’ll see you again in a weeks time.

Kit

Available Now, Daewoo Folding Bike

IMG_1984

Right now we have an auction for this lovely little red Daewoo folding bike ending this week,

Perfect for commuting making it easy to hop on a bus or train, and it’s easy to store too. It needs a clean up and a bit of a service but hey that’s part of the fun of it! And with this auction starting at the bargain cost of 40 quid delivered it’s a great deal.

You can find the auction here, But hurry not long left!

Site Update: Checkout Issues Resolved

Over the last couple of weeks we’ve been experiencing issues with the checkout hanging (grayed out in effect) with the loading symbol, leaving you unable to complete your purchase.

We’ve resolved the issues as we believe the cause to be NextGEN removed from our back-end (WP) pun intended it’s a case that some of our images may have disappeared and we may have to relocate some of our gallery images, so a new pain emerges. The side effects of expansion continue, please bear with us whilst we figure out our options we are looking at increasing server end.-

If you find any issues or have any suggestions, please don’t hesitate to get in touch by email.

 

Lil Wayne: Bring It Back ft. Mannie Fresh

Corinne Bailey Rae: Put Your Records On

Summer has started, Girl, Put your Records on!

 

Brazilian Girls – Good Time

Catchy little tune…

 

They’ve got quite a sound about them, sassy sounding sexy breathy vocals, creeping strings allude to more…
Check out their whole album.

 

She Makes War : Slow Puncture

With all the melancholia that the title suggests, I kinda like it.

She, equirrelling around London on a bike, gathering trinkets in her basket she rides past confused Storm Troopers and takes you on a tour of street art in East London.

A magical bicycle treasure hunt around the street art of East London…and some STORMTROOPERS.
