Aluminium ALLOYS: LIGHT & RESPONSIVE

We chose Aluminum as our frame material as it is 12 percent stiffer and 20 percent lighter than steel in it’s most common bike tubing configurations. Aluminium is rustproof and it dampens vibration 50 percent faster than steel. To add to this our unique frame design which includes a rectangle top tube and large to small bottom tube is engineered to provide additional strength. In order to guarantee strength, 6061 series aluminium was used and was very precisely thermally treated after being welded. is eight times as stiff, but only half the weight.

Hubs & Rims

 

 

All Alloy

We elected to have our bikes ride on double wall BMX alloy rims. Double wall rims provide the additional strength as well as provide additional suspension. We didn’t want to provide your standard 20 inch wheels as our bikes aren’t really made for tricks or the track. We have made cruising bikes on 26 inch, 29 inch and even 26 inch fat rims. Our bikes are more than capable of roughing it but we recommend that you don’t take them down a mountain bike trail.

Our alloy hubs with 32h which provide rolling capacity as well as spread the load allowing for even stronger wheels.

Disc Brakes

 

 

160mm Dics Brakes Front & Rear

Originally found exclusively on mountain bikes we decided to incorporate both front and rear discs on all our bikes. With their incredible stopping power, superior speed modulation, and better all-weather performance than traditional rim brakes, disc brakes make huge impacts on your ride. When you pull on a disc brake equipped lever, the resultant braking force is much more consistent. This reliability allows you to accurately judge how much force you need to apply in order to achieve the expected result. So despite it being easier to lock up a wheel with a disc brake, the feedback at the lever means you are far less likely to do so.

Cranks & Bars

 

 

3 Piece Cranks & Ultra Wide Bars

We opted for Chromoly BMX cranks because of the added strength. BMX Cranks take a pretty serious beating from hard landings or straight up wear and tear, so they need to be built tough. All our cranks are 3 piece Chromoly with a Thump chain wheel.

All our bars are 29 inch wide providing a real cruise feel and allowing you to relax whilst riding. Fitted with Sinz grips for ultra comfort.

Tires

 

 

Big & Fat

Here at Thump, we looked into the ideal tyres for our bikes. Our 26 inch and 29 inch bikes riding on mid BMX style tyres providing grip on and off road. We decided that we wanted something special for our fat bikes and created a unique style of 3 inch tyres on a 4 inch BMX fat rim. This provides a wide patch area as well as giving the illusion of low profile tyres.
