Revos ebike kit

Just read about it on BR. Claimed weight of only 2kg all in with 100wh battery, 250w motor, (automatic assisted) range of 10 miles or more depending on the size of the bottle cage battery, but I think most significant of all the whole thing can be fitted to (and taken off) most bikes in minutes.

Re: Crank bolt bottoming out?

My chainline calculation was based on Sheldon Brown writing " if you install a J.I.S. crank on an ISO spindle, it will wind up about 4.5 mm farther in than it would on a J.I.S spindle of the same length". The main reason why you are getting a greater chainline than what your calculation s...

Re: Fully suspended Spa Tourer

Well, not quite. With Suntour NRX parallelogram seatpost and Suntour hybrid CR-8 suspension fork I don't know if you have tried riding it, but those forks will change the handling of the bike as designed, quite significantly. Suntour is not exactly renowned for offering detailed info on their produ...

Re: Advice needed on derailleur

How about this as I can get free next day delivery and I was reading and it appears that this is the replacement for the TX35. https://www.amazon.co.uk/Shimano-Rear-Mech-TY300-direct/dp/B01DN3VQGW/ref=sr_1_3?ie=UTF8&qid=1492790805&sr=8-3&keywords=Shimano+tourney It would be a fine repla...

Re: Deore hub failures

I have come across a lot of Deore M525 8/9/10 speed hub failures where the seals have failed to keep the water out and the cones have worn or pitted. Usually, but not exclusively rears. Sometimes at quite low milage for what should be a reasonable quality hub (or perhaps Deore doesn't amount to muc...

Re: Reinventing the wheel - Cannondale AI

Not just the rear triangle, they are moving the entire drivetrain 6mm to the right. (Crankset, cassette, F. & R. mechs.) They say they are keeping the same "Q" factor, but I don't see how that works? Quite easily, I would have thought. What is important to note is that the system is a...

Re: MTB trigger shifter and road front derailleur

Front mechs fitted to trail bikes with flat bar shifters all use MTB cable pull standards, so any MTB shifter should be compatible. Shimano called these front mechs road mechs because they were designed for road sized chainrings. This caused a lot of confusion as it implied they were compatible wit...

Re: Shimano freehub bodies.

Thanks for the info. Those previous threads are very short, which makes me suspect that not many people have much knowledge of this subject, and why my new thread hasn't had many replies. Even Sheldon Brown doesn't have much to say except that that Shimano freehubs are usually interchangeable - exc...

Common Shimano freehub replacement (Y3A398020) found unfit for purpose

I think it has been for over a year now, that one of the most common freehubs sold by Shimano is different to the original it is supposed to replace, and therefore incompatible to many hubs it is supposed to fit. The freehub in question is Y3A398020 - it is standard replacement part for the FH-M510,...

There are some tools on ebay that are ridiculously cheap.

Re: HELP NEEDED! ... FIRST TOURING BIKE BUILD

First bike build and looking at making up your own drivetrain? this may not be a good idea. Why don't you read up a few threads currently on the boards looking at front mechs, chainline, etc.? http://forum.cyclinguk.org/viewtopic.php?f=5&t=111766 http://forum.cyclinguk.org/viewtopic.php?f=5&...

Re: Do shimano sti shift levers work with DX cranksets?

To be safe, it might be best to remove the inner ring of the existing chainset, torque it up, and do some careful measurements to find out what chainline is needed for what inner ring size. Each additional tooth increases the radius by 2mm. If going for the square taper route to game the chainline (...

Re: Shimano free hubs. 7 & 8 speed differences

A further question. Can 105/Ultegra rear hubs 5600/6600 onwards be respaced to 126mm? I have got spare 7sp HG freehub bodies. To my mind whether it is 5500, 5600 or 6600, they are all eminently respaceable to 126mm with a 7sp freehub, for the simple reason that we are talking about shrinking only 2...

Re: 9 sp chain on 10 speed shimano cassette

Last time I looked, I figured that 9 speed chains are generally wider (~6.6mm, up to 6.8mm) than the gaps (6.3mm Shimano, 6.54mm Campag) between the two adjacent 10 sp sprockets. There is no "standard" for chain width, so YMMV. That is not to say it won't "work", what it does mea...
