External bottom bracket - how much friction should there be?
On the weekend I installed a brand new XTR bottom bracket and XT crankset into a new frame. Before installing the chain I was interested to see how freely the crankset would spin. To my surprise I found that the crankset could not maintain momentum as soon as I stopped turning it.
I've taken off similar components on other bikes and never thought to see how freely the crankset spins. Has anyone tried this themselves and had different results? If so, any suggestions on why my set up seems to have a lot of friction.
Before people ask:
- I greased all the parts that need to be greased.
SRAM vs Shimano shifter action, a revelation
I feel like such a putz so I'm looking for reassuring words. Am I the only one who didn't realise you can use a Shimano trigger shifter like a SRAM? i.e. you can change up by pushing with your thumb as well as the 'traditional' Shimano way of pulling with your finger.
Calling all wheel builders. I need help with spoke length
I managed to spectacularly pull a spoke nipple straight through the rear rim on my commuter last week. It looks like someone has shot a bullet through the rim, consequently the rim is cactus and needs replacing. It was a cheap (OEM) rim on a cheap (OEM) hub so don't want to replace it at great expense with something super light and expensive. Because the hub is still ok I've decided to save a few $$$ and have a go at building a wheel myself. However I am having trouble determining which spoke lengths I need.
Bike Rack for Yukon ?
Hi guys. New to the world of MTB, having just purchased a 2009 Giant Yukon dually. The only problem is that I cant find a tow bar mounted bike rack that fits, due to the oversize bar. I have taken it to my local bike shop and they had nothing that suits.
Anyone know of a bike rack that suits such larger frame duallies.
Is there a difference between Shimano BB71 or BB91?
I noticed a creak in the bottom bracket this morning, obviously due to too much wet sandy riding. The specs for my Reign state it has a Press Fit Bottom Bracket BB71. I cant find any shimano tech docs on a BB71. I can fnd tech docs on a BB91. Overseas I can find BB71 for sale but only BB91 in Aus. I am guessing a BB71 is in fact a BB91. Can anyone confirm if they are indeed the same or if they are different. I will need to order one as you cant just rip the cups out and regrease (I dont think) but have to replace the lot.
Fork servicing
Hi Team
Just a quick search for advice and experience: how hard/technical is it to service your own forks? Rather than paying someone else to do it on a regular basis is this something that can be tackled by a competent home mechanic? I'm assuming a regular service would be seals, oil and a general clean-up, is that right?
The forks in question are Rock-Shox SID Race
thanks in advance

Strap On Bike Racks
Hi All,
I am looking for a strap on bike rack for my Mazda 3 Hatch.
I cannot get a towbar so that is not an option.
I would be carrying 3 bikes at most, more likely to be one or two.
any advice is appreciated.
Pocket Chainsaw
How awesome is this... perfect for clearing larger branches and fallen trees from the trails. They say it only weighs 200g so would make a good addition to any backpack after a storm.
Shimano QR Hub Cone Adjustment
Hi all,
Quick question relating to Shimano QR hub cone adjustment.
Do you 1) leave the tiniest amount of play before installation and let the QR compression take it up?
or 2) Adjust the cones to have zero play prior to installation of the QR?
I have been doing No.1 but not sure if there is enough bearing preload being applied. (There is no lateral play in the wheel once installed)
Interested to know anyones thoughts/experience on this one.
