An expensive change...

... -welcome to the range of little tuning for a lot of money. The switch of boltss is the last way to lighten your bike. Titanium and aluminium bolts replacing old steel bolts. And this is very expensive! One gramm less, costs more than one euro. The first step was the Pivotalbolt from steel to alu: 20g less for rather 7 Euros. Additional my underboss stem at 10g by using ti-bolts. And the seatclamp bolt is loses 4 gramm.


A good Place for bying Ti bolts is this shop. Who wnats to do it like me: Every bolt can be changen which is less burden by alu-bolts (for example:seatpostbolts etc.), higly burdened bolts only by Ti-bolts. Do it as long as your financiell situation allows it.

Haunebu F480 Dirt&Street Fork

Haunebu is going back to the Dirt-/Streetscene. They come back with an fixed fork with the installation high of 480mm (which is like a 140mm suspension fork). The headtube is in 1 1/8" and 6mm strong. By this high of installation and the pipe diameter of 31,8mmis the weight with 1,6kg eally nice. (but there exist a lot of more beautifull an more lighter forks). More facts: for 10mm Axis, for 160mm discbrakes.

Dropout tuning:

No, i'm not talking about an light measure, rather about the low-budget thematic. The Problem: 10mm Dropouts, but 12 or 14mm hubs and no money for changes or something new.
The Conditions: Steal-frame and drop outs, which aren't too short and some kind of tootime flavour :) .
You need: File, wire brush, caliper rule, thumbtack, rule, tape, a vice and a cloth. maybe a cutting disc.
Attention: Inform yourself about the guarantie, if you are allowed to customize your frame.
This case handles about a Perv Street, the mother of all low budget bikes.
We bring a 14mm WeThePeaople hub du the frame. The Dropouts at this frame usually are very big, so that no one must think about problems with stability.
We beginn: Save your chainstay by using the cloth and put the frame to the vice and go on. The best was is to file the lower side of the dropout. So you have the guarantie, that the hub not will be fixed wry, even if you file uneven.
If you even have to go to both direction: work fair! The best way ist to use the caliper rule and draw a line, where the last point of filing is. The Tape helps you to illustrate the drawing.
Everybody who filed before knows the lenght of such a process. So you can, if you want, go the first part of the way by your cutting disc. Please youse a new disc, beacuase of contingently sediments on the old disc.
If you do it by the cutting disc, don't trust on your drawing, check it often if you cut on the right way, after cutting finish your work with the file and make it looking good.
A tolerance about 1 mm in the end isn't tragicly.
Note: If you just file in on direkcton, the Geo of the frame changes.
