gears

On one inbred 29er swap out frameset size large set up with Shimano Alfine 8 speed hub gears, Rigid Kona Project 2 steel forks uncut, SLX brakes and Schwalbe Marathone MTB tyres. Very reliable commuter located in Accrington. Prefer not to post for the usual reasons can meet up within reason make...

Hi, after I fixed the punctures on both wheels of the Raleigh Motus GT eBike I took it out today for a spin. I now can't select the top 2 gears i.e. the smallest two sprockets on the cassette even though the indicator on the shifter tells me I'm already in 9 (it's a 9 speed cassette, Shimano...

A conundrum, how do you go about tweaking the gears on indexed dellraliuers? If you have a LWB or a trike, and happen to be on your own , I don't see how you can turn the pedals , and adjust the indexing at the back. I am a short Strapping 6'3" dollop, and even with my reach I can't do it, the...

I'm getting occasional chain slip when I pedal hard in the smaller rear gears. It's occasional and intermittent, so I'm not sure whether it's that my indexing is inaccurate or has some other cause. What symptoms should I look for to determine what the problem is?

Hi, This is a similar post to @Biker2772's about slipping gears. I suppose all cases are different, so I'm posting my own thread and I'll paste below some detailed images. The gears Ultegra with this code embossed: "RD-6500 VIA". The bike, a Principia Rex, is 20 years old and I bought it...

So when I had my old chain, the gears would not slip while pedaling with hard force but when I put my new chain on and sized it to the same exact size as my old chain, it still slips. It only slips on the highest gears on the rear and front. I have attached images for the freewheel, chainring...

1. Learn that clockwise on a barrel adjuster loosens a cable and counter clockwise tightens it. That's all folks....

During a ride the other day i noticed my gears getting a bit stiff towards the highest gear its 1x9 it wasn't also changing very smoothly was ok though so when i got home i used the adjustment barrel on the leaver and seemed to be ok. Took it out just now and they wernt smoothly changing again...

Have been racing (TT's) on fixed for over 25 years. Usually start off the season riding a 50x15 (88"), then move up to 50x14 (93") as I get fitter through the season and very occasionally use my 50x13 (101"). Nowadays, I only ride our club 10's and our course is a grind to the turn and a flyer...

Hi I’ve got a set of xt m8100 brakes and a set of altus 9 speed shifter I’ve been trying to look but not sure if I’m looking rite but I’m wondering if theys adapter so I can combine to one or do I have to buy a new shifter thanks

After having spent the last year getting to know my gearing and how it works, I've come to the conclusion that there is no such thing as a one size suits all perfect setup. For my ride in and back from work, it's important that I can change down in a flash as the gradients get steeper. A very...

My wife has a giant Sedona se, it's quite old but works perfectly, or so I thought! Just got it out of shed and it wont change on the front gears. The cable hangs loose but the levers seem to work fine, just dont moving anything ! The main spring was loose and could be moved round with my...

End of last year I bought a Willier Triestino Motirolo off eBay on the recommendation of a friend. It's a fabulous bike and I'm truly thrilled riding it but... The gears are Campagnolo Athena and they are mostly as crisp and slick as I could wish for. However...going to the smallest cog...

Hi Guys, Before I make things worse :) I thought I would as a quick question here first. Out on a ride yesterday with my wife, her Ridge Back hybrid suddenly would not change down below 5th. If you change up to 6 & 7 it will change down, but not below 5th. I was thinking it cant just be a...

Hello, I am trying to put together a nice set of gears for my new touring/commuting build. The bike will be built by my LBS, but I am picking components and trying to figure out the compatibility between these two groupsets. For my chainset and cassette, I think I would like to with Alivio...

Hi, so recently I have realized that as I try to shift my chain from the small ring to the big ring in the front derailleur a lot of times it does not get to the big ring. However my question is when I try to shift it to the big ring, why it does feel a bit harder to pedal yet the chain has not...

Threads on gear ratios always tend to have some people saying that it's pointless to have big gears, e.g. a 53 chain ring at the front or an 11 or even 12 sprocket on the back, because when are you ever going to use them on the flat, and if you're going fast enough downhill to be using them then...

(I must be going mad, thought I posted this already??) Hi All Been away for a few weeks, been down in London but took my bike with me!! Been doing a few things on the bike, New grips (not Ergon), new right pedal. Secondhand Brookes saddle!! Dont know whether its my little legs but I find the...

Somebody linked me to this Chopper which came up on Fecesbook, but I don't remember ever seeing them with twist grip gear change, the ones we had were a lever on the crossbar.

Having made the jump from 8 spd to 11, I'm struggling to see the massive benefit of having more, can someone enlighten me? Both cassettes were of a similar range (11-26) I still don't use the smaller end apart from stopping spin out on drops. Even then, never 11t. Gear changes are smooth but the...

Notes on lubrication for internal hub bicycle gears You’ll have to google centi stokes (cSt) and centi poise (cP) and how to convert them! J. Basically there are 2 issues looking at viscosity: 1 a lot of manufacturers state viscosity at 40 C or the use cP and cSt, which are different depending...

Any thoughts on why my gears are jumping from the lower gear to the next one higher at random times,new bike as well

I see quite a few of what look like Tri or TT riders when i'm out, always going in the opposite direction of course and more often than not cruising along at an insane pace but turning the pedals real slow, looks like 70rpm (very rough guess but certainly slow). They usually take the flatter...

I have recently purchased a 1930's Hercules tandem in original condition minus a few parts. I need the rear durallier which are mounted on a plate beneath the bottom frame stay (not on the drop out) however i'm not sure what to look for or what names or manufacturer to look for? Any help greatly...

Why don’t e bikes come with the above. The weight penalty is not a big issue and sue the minimal maintenance helps?

I'm having trouble adjusting my rear gears, I've set the limit screws for the smallest cog and the biggest cog. What seems to happen is with the chain in the smallest cog I change up one Gear to the next biggest cog if it doesn't change i tighen the cable via the cable retention screw. Once it...

Hi all, Recentley pulled my winter bike back out.. To find the gremlins had been at it. When the bike was put away all was working fine, no problems whatsoever. First outing the gears where slipping. Typical problem I can set it up and the gear change will be fine for the fist 4 cogs and then...

On my Btwin triban 3. I started out with an 8 speed cassette Then changed it for a 9 speed and thats what I'm running with now Though am wondering if I can change to an 11 speed cassette as there is a quite big spacer on the opposite side (between the frame and wheel) Is there any way I can...

You good people usually have the knowledge and I expect it is an easy fix. Had a new cassette fitted by a bike shop prior to bringing my old Allez Sport back to holiday home. Rode it a few times here and constant ticking in various gears and sometimes am having to "re-engage" the gears so to...

The kid's bike is a bitsa bike. She's only recently started using the gears on it, and hence I've discovered they do not index. On closer inspection I thought I'd diagnosed it straight away - I'd inadvertently fitted a 6 speed grip shift (because she likes grip shift) with a 5 speed cassette...
