My Trials Bikes

[CPHun]

The photos aren't the bests and the bikes are dirty...

Adamant A1 Mod: weights ~9,8 kg

This was a black Try-all front rim. (-60 g with the bigger holes and without paint)

The rotor was round. (-9 g)

These were gold Echo CNC cranks (-15 g)

Single walled Jetset rear rim with bigger holes (-160 g)

Home made Coust pads.

Magellan tucana 20": weights ~8,8 kg

(now the frame is 1778 g)

This was a red double walled Zhi front rim (437 g).

Now the rim is 345 g.

Brake adaptors for 350 mm long chainstays.

(Original chainstays lenght was 362 mm.)

I don't know the name of these cranks but they're light. (447 g)

These pedals weight 297 g.

Made from 249 g XC pedals (Cr-Mo axle) + VP cages.

Zhi rim with larger holes (-74 g)

Home made alu backings and rubbers from broken Rock pads.

So you shortened the dropouts to save wait and put the adapters on ?

Or have i got the wrong end of the stick ?

Either way the both look good, prefer the Adamant though...

On this picture you can see the setup without the brake adaptor.

Yes, I shortened the dropouts a bit but I could use the frame without adapters because the dropouts are long enough now too.

One peace of chain shortens the CS 12 mm.

The wheelbase of the frame is 1067 mm without adapters with 362 mm chainstays lenght.

The WB of the frame is 1055 mm with adapters and 350 mm CS lenght.

I felt the 1067 mm WB too long for a mod bike because of the small wheels and the long distance between them.

With shorter chainstays you can move the bike easier. (Tap is the only move that's worse because you can't do it so high.)
