As I was changing the cassette on a Hope Pro II hub I decided to have a quick check to make sure the freehub was doing fine. It's a good job I did as 2 of the 4 pawl springs had broken and a 3rd broke when I prodded it. I think I'd better get them replaced before I head off to A Quick Release next month!
This is the second time in 3 years of ownership that I've had to replace the pawl springs in this hub. Is this common? It seems fairly poor and I doubt I produce such unusually monstrous torque for this to be unique to me. My hardtail's Hope XC rear hub is 6 years old and its pawl springs are the originals and they're doing fine. Mind you, it's had its bearings replaced twice now and the Pro II's are doing fine so did the change from XC to Pro II replace one minor issue with another?
Does anyone know if any Edinburgh LBSes have Pro II pawl springs in stock or is the wheel likely to be out of service until next week now?
We have em.
Call in tomorrow and James will sort it our for you.
Dammit
The leafsprings in my Pro2 hubs seem to go on a regular basis.
I hoped that one of you would see this. 🙂
I should be able to get to your shop (just) before 6 tomorrow.
Call me if running late and i will stay back a bit.
Cheers!
It's caused by too much freewheeling. Think about it. When you're pedalling the springs just sit there - no movement, no pressure. When you freewheel they bang in and out all the time, work harden and die.
The answer is, stop being so lazy and pedal more.
We treat them as a routine service item, seems that all the flexing is concentrated at one point rather than along the entire length of a coil spring,leading to fatigue and breakage.Plus point is the freeewheel mechanism is usually full of crap by this point, so you can't really ignore it and put off an overdue service like you could with the previous ones.
They go all the time, I think there sh1t, hope sell loads of replacements though, so good for the economy.
I could do with some how much are they?
Not much. £3 for a set.
£3 for 4?
Mine used to disintegrate a lot til I stopped using Muc-off!
Its a moving part!
Twice in 3 years...pretty good to me!
Chris - got to leave early for a mortgage paper sign off thingy so can't stay back... call WIll and get him to hang for you. I will speak to him later anyway. We could always leave them perched inside the letter box if all else fails.
look on bright side at least Hope hubs are easily serviceable and full stock of bits and pieces genearlly can be found; on my Pro 2s have had 2x sets bearings replaced + pawl leaf springs in last 5 years which is I feel fairly good, better than having to bin whole unit thro lack of bits isn`t it???
3 sets of pawl springs in 2 years. All hope products I have ever owned have been rubbish.
I run three sets of Pro2 hubs. Two of the older ones have presented no problems. The newest one from last April needed replacements after six months. I pulled a friend's Pro2 apart last week because it had gone non clicky and all four springs came out broken. That was less than a year old.
I now make sure I have a spare set with me or have replaced them before any major trip.
It is quite often the case that one small bit failing can render the bike bloody useless and these leaf springs are a case in point.
I have one set that has lasted 5 years - only just replaced them - I hope they last another 5 years 🙁
I should be able to get to the shop before 6pm without too much difficulty. If they're £3 for 4, I'll probably get more than one packet, in case this happens shortly before a big trip again.
From a user serviceability point of view, failing pawl springs are easier for me to fix than the XC's failing bearings as I lack the skills (and probably the tools) to knock out bearings and put new ones in.
the ones on my singlespeed went over the course of last winter. The sealing isn't great if you wash the bike requently water gets in and you need to replace them after a period of time. This is not helped by clickyness being dependent to some degree on not putting much grease in there. So, over winter the singlespeed will have the freehub body removed frequently for regreasing! It only takes 10 minutes and the only issue is loosing my beloved click!
