|   Hey Nino or anyone else...that list of all the bolt weights | Not Duckman
Jan 18, 2004 4:27 PM | | ...I thought i had it, but it most have been on my Hdrive that died this past Sept. Did a search here, but still can't find it.
Um...can ya help a brotha out?..i guess is what i'm getting at.
Just ordered some..stuff..from Racebolts. How bout blue ano 7075 Haye hydros breakdown bolts(the one that hold it together)? Maaaaaybe red frame mtning bolts? Ti upper and lower nrs shockbolts(egad!=$$65mm/35mm), alum washer, and Ti locknut($egads again on the damn ti locknut)for the lower shockbolt. All three bikes will finally be completely ti or alum after this...um..wave. Also replacing some stuff currently ti(say the pod pinchbolts on all three rides)to alum(blue or red sounds pretty me thinks:).
Ops..just remembered..2 RDs are still steel hardwared short of a ti cable pinch bolt, the other has the SRP RD kit deal. Damn!
Does it ever end??!:) |

Jan 19, 2004 3:01 AM | | the only place you need the added strenght of Titanium is at the stem and seatpost.all other bolts can be out of aluminum which is also a lot cheaper than Ti.
Aluminum (savings over steel):
Chainring bolts (2x5pcs) -30g / (2x4 pcs) 24g
Crank fixing bolts -15g
F-derailer (2 main bolts) -5g
R-derailer (hanger bolt,cable stop bolt,pulley wheel bolts) -ca.10g
A-head cap bolt (M6x20mm) -4g
Bottlecage bolts (4 pcs M5x10mm) 7g ( Al =3g /Ti =6g /Steel =10g)
Brake lever bolts 5g
V-Brake canti bolts (4 pcs M6x15mm) 11g
V-Brake cable fixing bolts (2 pcs M5 or M6x8mm) 5g
V-Brake brakepad fixing nuts (4 pcs M6) 10g
Cassette Lockring 10g (steel 14g / Al 4g)
Pedals ? -10g (my Corratecs had 8 steel bolts)
TITANIUM (savings over steel):
Chainring bolts (2x5 pcs) -15g / (2x4 pcs) 12g
Crank fixing bolts -10g

Stem (4-6 pcs) 5-10g
Seatpost (1-2pcs) ca. 3-8g
V-Brake canti bolts (4 pcs M6x15mm) 6g
V-Brake cable fixing bolts (2 pcs M5 or M6x8mm) 3g
V-Brake brakepad carrier bolts (4pcs) -8g (Ti=12g / steel = 20g)
Ti bolt-on axles instead of QR -70g (typical steel QR levers 120g .bolt-on axles Ti= 48g / steel 65g)
Carbon (savings over aluminum):
A-head spacer -6g /10mm ( Al =10g/10mm / Carbon = 4g/10mm)
V-BRAKE TUNING:
4 Canti-bolts M6x15mm : steel 16g / Ti 10g / Al 5g...................-11g (Al)
4 padcarrier bolts: steel 20g / Ti 12g..............................................-8g (Ti)
4 pad fixing nuts M6 : steel 14g / Ti 9g / Al 4g.............................-10g (Al)
2 Cable fixing bolts M6x8mm (Avid) : steel 8g / Ti 5g / Al 3g.....-5g (Al)
Total possible savings : -34g
Example for maximum possible BOLT-TUNING on a MTB:
ALUMINIUM:
Chainring bolts (2x5pcs) -30g / (2x4 pcs) 24g
Crank fixing bolts -15g
F-derailer (2 main bolts) -5g
R-derailer (hanger bolt,cable stop bolt,pulley wheel bolts) -ca.10g
A-head cap bolt (M6x20mm) -4g
Bottlecage bolts (4 pcs M5x10mm) 7g ( Al =3g /Ti =6g /Steel =10g)
Brake lever bolts 5g
V-Brake canti bolts (4 pcs M6x15mm) 11g
V-Brake cable fixing bolts (2 pcs M5 or M6x8mm) 5g

Cassette Lockring 10g (steel 14g / Al 4g)
TITANIUM:
Seatpost clamp bolt 3g

Canti brake bosses on fork (2 pcs) -6g
V-Brake brakepad carrier bolts (4pcs) -8g
Stem (4-6 pcs) 5-10g
Seatpost (1-2pcs) ca. 3-8g
Total possible savings: ca. 150g
remember:
Titanium is about 1/3 lighter than steel
Aluminum is 1/3 the weight of steel and 1/2 the weight of Titanium
Carbon is about 1/2 the weight of aluminum |
