- Fitting a star fangled nut
Had to laugh the other day in our shop. A customer had brought his bike in as he had “attempted” to fit a new set of forks he had purchased. He had driven the star nut that far down the steerer tube it was unreal but worst of all he had then driven it back up the steerer tube! This had caused the tube to split and so trash a brand new set of forks! Luckily the steerer is replaceable but why did he think he could fit them when he clearly hadn’t a clue. Just beggars belief at timesPosted 9 years agoivan_w_1983Member
I just got a pair of forks from merlin cycles and the star nut was at a 30° angle. It wouldnt move, luckily I had top lop of the top of the tube anyway and the guy at cycle surgery gave me a free star nut.Posted 9 years ago

Sacrificial bolt and hammer. There is a tool and it essentially does the same thing with a guide.
The SFN isn’t structurally important. Once you’ve tightened up and compressed the headset you tighten the bolts on the stem which is what structurally holds everything together. Or so I’m led to believe, no doubt someone will claim otherwise…Posted 9 years agodoboMember

Cheaper at Merlin
Given the price of forks and headsets, I really can’t understand why anyone would scrimp on another £8.50 for a decent tool.Posted 9 years agoAnthonyMember
I have spent about 10yrs faffing about trying to knock them in straight using just a bolt. It always worked but was a bit hit and miss. After spending £15 on the Pedros tool I really wish I had done it back in 1998.
Screw on nut, slide over steerer, whack with hammer, job done. Perfect depth and perfectly straight. Perfick.Posted 9 years agocoffeekingMember

Top Tip: dig out an old canti brake block from the bottom of the toolbox. Thread it into the starnut and give one clear clear sharp twit with a hammer. If it’s a good clean blow it will be in dead straight. If you pussied it at all it will be a bit skewed. Just spin the brake block around to the right angle and tap it straight. Satisfyingly pikey-cheap yet efficacious.Posted 9 years agowarpcowMember
Sorry to revive a dead thread but I just need a little clarification on what the suggested screwdriver might look like. Am I correct in assuming that the drivey bit (hence the question 😳 ) should go all the way through so the handle sits up against the nut, and that the handle should not be so wide that it blocks the edges of the nut from bending? Otherwise I just managed to bolt a stack of washers to the nut, will that be fine too?Posted 8 years ago
