Raleigh MV8 Mini Velo Thread
In September, I bought a Raleigh Mini Velo 8 from my LBS in Singapore, I thought it looked nice and would be a rather affordable commuting rig.
Stock version http://www.raleighsingapore.com/wp-c...elo8-black.jpg upon purchasing it, I made some upgrades to the bike as I preferred a road bike-like position. end of the day , it stepped out of the LBS looking like this http://i128.photobucket.com/albums/p...psycuahdh9.jpg After riding it for several months, bringing it with me along road bike group rides, I detested the fact that the stock wheel was crap, not only was the wheel untrue, but the bearings was lousy, I was also constantly on the last 4 cogs of my cassette, always out spinning it when the going gets going and wanted a more mordern feel to the bike. went back to the LBS and after a week or so of tinkering with it came back with this http://i128.photobucket.com/albums/p...pslshamb1r.jpg Full build list http://i128.photobucket.com/albums/p...psugjkz2y3.png The full build has a rough estimated weight of 9.3-9.4kg (measured using weighing machine + body weight) Opted for the 61t gehardt chainring as i felt i could use a bigger chainring, mated to a SRAM S300 courier crankset. Didnt get to weight these as the LBS had to destroy the old 48T chainring and bolts to get the new chainring on http://i128.photobucket.com/albums/p...psvh1rndxv.jpg http://i128.photobucket.com/albums/p...pslvmhngxz.jpg http://i128.photobucket.com/albums/p...psnafixo59.jpg Wheels are the litpro S42 406 wheelset. which is basically a 42mm rim height 406 rim. Didn't get the weight as it was delivered to the LBS and by the time i remembered about it, tires and wheels are mounted Tires are some Kenda 20x 1.0 tires. Braking are handled by a pair of SRAM single digit 7 Brakes, the promax that came with the bikes are lighter, but the single digit 7 are easier to maintain and wheel removal is easy. http://i128.photobucket.com/albums/p...psxza17wwa.jpg http://i128.photobucket.com/albums/p...psxwudzypv.jpg http://i128.photobucket.com/albums/p...psx2hwt04v.jpg |
Handlebar are some Time egrodrive handlebars which i grabbed cheaply off a sale. it came with a channel to run the cables smoothly
http://i128.photobucket.com/albums/p...psgvv3w9j7.jpg http://i128.photobucket.com/albums/p...psl56xwpov.jpg Shifting duty is done with a mix of tiagra, ultegra and 105 stuff. http://i128.photobucket.com/albums/p...psadh1t6pf.jpg http://i128.photobucket.com/albums/p...ps5rccanlv.jpg was rather surprised by shifters still work as I stored it for about a year from my old race bike and rust and grime was everywhere. saddle is the fizik antares which i use on all my bikes. http://i128.photobucket.com/albums/p...pst6qbrmmh.jpg |
Very nice and admirable job.
Questions 1. What shop in Singapore sells that 61T ring? How much and does it come in silver? What's the bcd? 2. How did you get v-brakes to play nice with road brake levers? They have different pull, don't they? A suggestion: a 451 wheelset, caliper brakes and Panaracer Minits Lite 7/8. |
Looks good. It's always nice to see a different minivelo since they are so under appreciated.

The bike looks great. How has it been working as your commuter?

Nice!
The Raleigh MV8 frame is really nice for upgrading. I think you may have got the last few since they now have a new design for the mini velo series. Interesting option for that 61T, did you get it locally? |

I actually have this bike too and its good to see someone else post about it.
Mine's built to be cheap though since its a commute and I do just lock it outside while I go about other matters. https://farm6.staticflickr.com/5782/...33ab32c3_b.jpg Raleigh MV8 by jenkwang, on Flickr Stock shifter and deraileur. 60T chainring

Stiff frame that feels like a road bike geometry. Rather long wheel base makes the bike stable. The pull ratio will be different, but it is certainly not a problem imo (YMMV) The 20" wheels don't need as much to decelerate compared to 700c, so the brakes are no problems at all. |
Luv it!!!

I managed to find one of the few remaining brand new sets of the mv8 online and got one for myself, only because of this thread! I was initially torn between the 2016 mini 7 and 8 - glad I found the older mv8 as this turned out to be the best option for me. The 2 bikes here look great and really inspired to start upgrading mine soon.

Hi, newbie here seeking help. I hv this mv8 and wondering if it can accommodate 451 wheelset. Also, I tried to change the stock crankset to litepro with 53t chainring but I think the chainline went off and regardless which length BB i use, the chain keeps slipping off either the smallest or biggest cog. It works fine with the stock 52t chainring and litepro crankset. Hence issue lies with the chainring. Any ideas anyone? Thanks |

No physical parts that block a larger wheel, V-brakes can be adjusted for the larger diameter.. But perhaps you can try this in a store? For you chain skip problem, have you adjusted the RD/chain to cater for the additional teeth? I have 6 bikes that run 1x systems and they don't have a problem once adjusted properly for chain length/Rd |

I don't have 451 wheels, so I can't confirm its usage on the Mv8, but there does not seem to be anything on the bike that would prevent it.

I hv a long cage derailleur and chain is good for the 53t. It works perfectly with the same crankarms + low end 52t chainring. But once I swop chainring to 53t litepro, it'll derail off either the biggest or smaller cog, depending on which length BB i use. Seems like this litepro chainring is the culprit as I borrowed a friend's 53t chainring and no issues. Thanks for your help. |
Sounds like a chainline issue, too far to one side. I have a Litepro crankset that came with its own BB and spacer. Try playing with that.

my 61T has stopped chain slippage after I change the deraileur due to the broken adjusting cable tensioning screw |

The V-brakes will not adjust from a 406 wheel to a 451 wheel. You will have to go to caliper brakes which will usually mount to the fender hole that is centered above the wheel.
The Road levers when hooked to V-brakes have extreme stopping power. road levers have 2:1 leverage vs v-brake levers which have 1:1 leverage. Since the cables only move half as far, your wheels need to be really straight or the brakes will not come far enough off the rims. The mini-v brakes for bmx race bikes have a bit less leverage. I am sure a good grip on the brake levers will send you off the front. Be careful. Really nice looking setup. Enjoy.. |

You need a Chain Guide. It prevents the chain from slipping off,...
CHAIN GUIDE Scroll down and you'll see it for sale. Thanks, I'll try that |

As you change the chainline you need to adjust the rear derailleur limit screws. Any shop can do it for you in about 3 minutes. If it is dropping off the high gear, you need to screw in the High gear adjustment screw a 1/2 turn at a time until it is perfectly lined up.
Thank you! I'll try that. How can I forget something so basic? |

it would most probably be the chainline ,
my 61T has stopped chain slippage after I change the deraileur due to the broken adjusting cable tensioning screw Might as well check the tensioner too. Thanks! |
:p Ah, Gram scale Cycling..

Upgrade!
451 Wheels https://farm5.staticflickr.com/4388/...f1e6ac15_b.jpg Raleigh MV9 sp Redone with 451 wheels by jenkwang, on Flickr My thrashing of the bike rain or shine as the commute+poor weather bike wore down the cheap China wheels and FSA BB bearings. I've never had issues with rusted BB on any of my bikes before, so no more FSA for me. Since I like this bike so much and picked up more ideas on what I want on a mini velo, I decided to upgrade it. The cheapo brake hoods (from Taobao) had the rubberized parts fall apart within months of use, so I opted for nicer Tektro RL520 levers. These are catered for V-brake pull ratios. Crank and BB was taken out and replaced with a Ultegra R6700 and BB. I left the small chainring on the bike in case I wanted to 'hand shift'. My use locally has never needed the smaller chainring, so I decided not to stack on more costs with a FD (for now) Resprayed some spots that had the paint chipped off. Finally, the biggest change was to a nice pair of Tyrell AM9 451 wheels. Yes, the stock bike is 406, so this was the area that needed some dice rolling and work to get it working. I'd go to the details in another post. |
https://farm5.staticflickr.com/4365/...b33e8a1f_b.jpgRaleigh MV9 sp by jenkwang, on Flickr
Here are the details of what had to be done to mount the Tyrell AM9 wheels onto the bike. Clearance wise, there is no obstruction for the 451 wheels to the frame/fork. OLD The OLD of the wheel is 130mm, but the Raleigh has a 135mm OLD. So a spacer was needed to increase this. Brake to Wheel Rim Since the wheels are now a larger diameter, the brake pads can't reach the rim of the new wheels. There is the option of longer V-brakes, but these are rather specialized and more expensive (w/o the option to try before I buy). So I opted for brake extensions. I wanted something that looked good, so my first purchase was these ones from LitePro. https://farm5.staticflickr.com/4485/...13a924f0_b.jpgRaleigh MV9 sp by jenkwang, on Flickr These fit on the mounts of frame/fork and look like a less "make do" implementation. However, only the rear ones could be used as the steel fork for the stock bike had welded mounting posts. So I had to buy another type of brake extensions, which to me looked more "make do". https://farm5.staticflickr.com/4514/...dc964633_b.jpg Raleigh MV9 sp by jenkwang, on Flickr Again, these are from Litepro. They seem to work fine and probably would be the safer bet for most bikes doing a 406>451 conversion. |
